In this video, homeowner Leslie uses GRA Secure Set Spray Foam to not only fill in the voids underneath her driveway just outside her garage, but to raise the concrete, re-establishing support underneath the concrete, reducing a potential tripping hazard and stopping further erosion. With Secure Set Spray Foam, you can lift your fallen concrete slab too, whether it belongs to a driveway, sidewalk, warehouse floor or whatever you have. You only need a 3/8 inch bit, masonry drill, some black electrical tape, and an idea of how large the void is and a timer. Also check out another video we posted for raising a concrete slab: • Foam jacking, concrete...

This video has everything of a real DIY project - needing twice as much as you anticipated, taking twice as long, the "wrong" thing moved first, and using a vehicle in a way it was not intended. :) Glad you showed everything and not just some "ideal" project.
Hello Nathan, Your comments have brought some laughter and smiles to the people here in the office. The homeowner, Leslie, actually said to us, you "Have To" show this video because it shows the real mistakes and the eventual success of the project. It was the true project, warts and all. We really do appreciate the time you took to comment, thank you Nathan
Wish you would have shown the slab after the car was moved.
Hello John, The car was used to anchor the edge of he slab. It did its job. All was well. Thank you
That's what made me interested enough to watch the entire thing and consider your product for a project I need to do in the future
@@SecureSet-Fence-Installationeree
I was quite disappointed to open my kit and not find a red shirt/blue jean private mentor included. Another classic case of Expectation vs. Reality. I attempted this on a simple 2 inch 20 foot sidewalk raise. I ended up with approximately 1.5 cubic foot on my clothes and on the equipment. 2.5 to 3 cubic feet expanded onto the surface. I accomplished raising one edge about 1/4 inch. What a mess. Thank goodness for Acetone. If you guys ever travel to San Antonio please stop by and show me how easy it should've been.
Some questions came to mind in the process that wssnt clearly explained:
1) why more than one nozzle? Was a new one used for each hole? Or just after returning after extended drying time?
2) how to determine how much tape wrapped on nozzle to prep it??
Is that to seal the size of hole while applying/filling w sealer. ?
3) how to know when to stop dispensing each hole? At each application layer?
4) how do you avoid lifting too much?
Doesn't it keep expanding after you stop filling?
5) prepping the nozzle , to clean/vacate it between applications of foam. Couldnt see what you did. Did you Empty hose of the foam, remove tip and then cap with a new clean tip?
6) what was the plug removed between holes? Was it the nozzle hardening quickly or a plug from the hole?
7) why spray foam into box before filling the hole?
Was the line filled with air?
8) what if there is an unknown big gap under the 12x12' slab further down the driveway? Maybe that is where the extra foam was going?
9) what does "hear air coming out of crack" indicate?
10) did the 1/4 inch raise on garage side come back down later after putting the car on it?
Or did pivoting primary slab level it after infusing more foam in holes?
11) would be nice to see cutting off final excess overflow foam from the cracks and final prep sealing of the joints where tar sealer was removed.
() great project video. I watched it twice! But still am not certain about the questions above. -RichK
Thank you for showing the entire process, really helpful. I would suggest wearing safety glasses anytime using the spray gun, it's so important to protect your eyes.
You are welcome. Yes, safety glasses are very important. Thank you!
Shut up 🐈
I did this for 10 years slabjack. I raised entire garage floors up to 9-14 inches,sidewalks,drives, great way to make a living atl ga
Thank you for the comment. Have you tried doing the same with our Secure Set Spray Foam? We talk to many customers that do mudjacking/foam jacking with their rig systems, but will use our kits for the smaller jobs instead of losing the potential customers that won't pay their normal minimums. GRA Services
Good video. I strongly recommend safety glasses or even better a clear face shield when working with any expanding foam product. It squirts out under pressure unpredictably. A disposable Tyvek suit over exposed skin will prevent messy and really difficult cleanup.
A word of advice to anyone watching this video.... never assume it will go the same as "most jobs". There will be variables but don't let it scare you. It might be wise for the maker of this material to have a list of worse case scenarios to keep in mind and how to be aware of them and how to improvise based on your situation. Overall it seems incredible that it lifted it. I wonder how well the foam holds up in time being saturated in dirt year round.
Hello Ron, Your words are correct. No job is totally alike. The worst case scenarios are hard to completely qualify prior to the start of a project. I find the more you investigate with hammer sounding and drilling a few strategic holes that allow you to probe and get a better understanding of the condition under the slab. If the home owner had the best tools, the small flexible "Bore-Scope" device that attaches to your iPhone would be the best tool to examine the underside of the slab. One insight I can make about the product holding up under the slab, is that this product is a high density, closed cell structural foam. It will not allow moisture or air to pass through it or saturate it. Here is a good example of the longevity of closed cell foam When the Alaska Pipeline was built in the late '70's, the concrete pilings that hold up the pipe above the ground, those pilings were set on a thick bed of closed cell foam. The reason was to keep the temperature of the heated oil in the pipe from slowing migrating through the concrete and possibly melting the perma frost under the concrete pilings. That foam is now almost 50 years old and it is still holding strong. Thank you for your thoughts and comments.
He is right. The closed cell foam is not going anywhere. I installed an aluminum fence and since you shouldn’t use concrete with aluminum I used closed cell foam, dug down past frost line added crushed gravel and set my fence posts and filled the holes with a product especially designed for deck and fence installation and building code approved. My fence hasn’t moved at all, while other fences in my area installed by so called “professionals” are pushing themselves out of the ground as much as 12” or more. The foam fills in all voids making it near impossible to be pushed out. It’s an incredible product. I’ll be using this on a sunken portion of my patio now I see this is in a kit.
This guy is an excellent instructor by telling, showing, observing, and praising/retraining as he goes along.
Hello Al, Thank you. actually the credit goes to Leslie. She was so tuned in to what needed to be done. The success of the project and subsequent video is because she dids he job so well. Thank you.
I like that Leslie jumped right in and wasn't afraid to do and try something new. She had a good instructor too! 👍
I appreciate you taking the time to document showing someone on camera what it's like to learn how to do this process because a experienced professional doesn't always anticipate the things that a newbie needs to understand for a successful outcome.
Good work all the way around by both of you! 👍👍😃
Hello Micah, Thank you !! It really was a fun and successful project. Leslie, really did get right into it ! Her house, her project!
Like my mom always used to say there are girls you date and girls you marry. She’s the marrying type 😀
She's a hard worker I would not wear shorts though and she probably should use knee guards. Work clothes for the job.
I knew concrete lifts could be done without a huge air compressor rig. Secure set foam for the win.
This is me on every project and then people start to wonder if I know what I’m doing once I start using cars as weights and Amazon boxes for test blasts. Great video
Hello mrjedmonds, On previous slab lifting projects, the concrete moved easier. However, with the project with Leslie, the slab started to move uniformly, instead of swinging up like a door. The best weight we had on site was the car, she was good with it, so we went with it and it worked well. Thank you for taking the time to comment.
Now we know how to repurpose all the Amazon boxes in everybody's house 😅😅😅
😂I loved when she threw them gloves! I knew she was about to get down to business😊I cheered her on😊
Would’ve probably been best to put some bolts through it, Jack it up to raise, then put foam to secure it at the proper height. There are ways you can put bolts through it, and chain them to 2x4s and use a hydraulic lack to raise it
Hello IntegraDIY. That is a good suggestion/option. We presented that idea to the homeowner, they were not too keen on the "Holes For Bolts" idea. So, we accomplished the job with just the lifting power of the foam. Thank you for your comment.
How excatly do you attach this bolts? I have attempted this a week ago and cant get a good attachment on the slab
Great video! I found the strategy of redrilling holes and layering the high density foam - from below - in conjunction with use of the ramps with the vehicle to weigh down the hinge point, most innovative. Thank you. Very smart.
Thank you so much for this honest video, showing what really happens with most projects....all the unexpected things that come up and how you handled them. Really great, informative video!
Hello Populist, Leslie, was determined to not only do the repair, but take the consequences as well. It all turned out well and she saved about 2/3rd's the amount of money that was quoted to her by two different concrete contractors. A few bumps along the way, we should have had safety glasses and knee pads, but we filmed it as she did it. Thank you
Very interesting. Glad you included things that can go wrong. Would like to see the homeowner using proper PPE. A dust mask and eye protection should always be worn. Drilling concrete creates silica dust which is potentially harmful. Otherwise, very informative.
Thank you! We don't want to hide what can sometimes go wrong in the process, it's better to be prepared. Yes, we started with the glasses for protection, but for some reason they were removed along the way. The directions and safety data sheets do explain the need for the protective equipment.
Super interesting and educational. One word of advice. Wear eye protection! Leslie nearly got an eyeful of foam. Yikes!
Hello John, Yes, that has been pointed out to us many times. :)
@@SecureSet-Fence-Installation And yet...
Great detailed video guys! As a home owner and self DIY'er really appreciate how you worked with Leslie for her to do most of the work while learning the process as it went along. Thanks so much for the detailed explanations and documenting the process fully from start to end, not as a montage.
Hello Jessica, It was fun to work with Leslie, she really wanted to do as much of it as she could. It was a full day, but in the end all was achieved that we set out to do. We were a little surprised that the voids under the concrete were quite a bit bigger than we anticipated. However, Leslie just powered on and we got it done. Thank you for your comments.
Sometimes the foam takes a while to find all the small cavities and voids. Once those are filled, the concrete will begin to lift. Thank you.
Load locks to the top of garage header may be a good solution for holding top of slab from moving.
Hello Rick, In hindsight, that would have been better. But the car worked and it did not delay the project or the videoing of the project. Next time, if we have a similar situation, we will look at that option. Thank you.
By the time this is all over, Leslie will be an expert!!
I just gotta $11,000 bid to do this to my sagging garage and driveway. Plus they fill in the cracks too and put something into the expansion joints. Just gunna do it myself now.
Have you done yours yet?
I just put 6 of these into a very sunk hawaii house foundation. It ate it all. 1 gun safety malfunctioned and i got blasted. The cans actually go well over ten minutes. I like the concept. wear protection. face shield even. I dont think the instructor emphasized the tight seal you need enough, and how to manage the ten minutes of foam you get. its really more like 12 minutes. This could use a lot more real detail. Good product.
Thank you for the comments, @Snoopy Ace. You must have had some huge voids, and/or you had loose non-compacted soil and the foam compressed your soil to create more voids than you expected to have.
Sorry to hear about the gun malfunction. Like any mechanical device things like that can happen from time to time.
As far as more real detail needed, the kits are used for so many types of projects that we don't put the application detail in the kits, but we have 10 instructional videos on TH-cam and our website www.secureset.net for help with understanding a few types of projects. Also, we are happy to answer questions by phone at 405-672-8885.
Thanks again, GRA Services.
This is a perfect no nonsense straight to the point video. I love it!
Great presentation! I like this method and have a number of projects in mind. That existing crack between your slab sections very likely provides some interlock, which might cause your first injection area slab piece to actually lift the next piece. When there is differential elevation across a crack, I believe I would try to release the sections by cutting/chasing the crack with an angle grinder and a diamond blade - maybe a small drill also.
Hello GrouseHiker, Very good point. We actually did use a sawsall with a concrete blade to relieve stress between the slabs. Once we did that the independent pieces moved more easily. Thank you, good eye!
Great video and it was cool letting someone like us show that even we could do it.
It gave me incentive to ask you about my back porch slab. We had a gutter on second floor roof go out. Before we could get that fixed, the damage it made for us, cause about a 12'slab by 6' to crack and heave. Against the house it dropped 5 to 6" and sits up about 3.5". Would your product be a good fit for us. From what you used, I'm thinking it would take at least 6 cylinders? Waiting for your input.
Tom
Good idea. In a way we are dealing with small tectonic plates that rise and fall with each other depending on the friction between them.
Most all of the comments support my saying that I really appreciated the honesty and straightforwardness of this vieo. It absolutely gave me the confidence that I can lift my sinking padio slab. Cannot imagine what went wrong in San Antonio though.
Good job!!! Nothing like a woman or anyone trying or learning to do something that most people would hire a pro to do! You two taught me a little something and I got some work to do it seems....lol. Enjoyed the video!
Hello Dennis, Thank you very much for your kind words. If you have any concerns, post your question, we can help you.
Hey, great video. I have a small area on my driveway that needs repaired. It’s, maybe 1/4 inch off… anyway, I called a professional…I just wanted them to use a filler to fix the crack. The pro educated me and explained settling, voids and foam lifting. Anyway, he proposed three options… the first option addressed the 2’ x 3’ area that needs caulked and apparently lifted 1/4 inch cost $2,500. Of course, for option 2, he wanted to “protect” my entire driveway (3 1/2 car size) that included a foam injection to create a barrier under the entire driveway for $7,500… and option 3 included options 1 & 2 with caulking the expansion joints and painting the driveway to make it look new for a cool $15,500!! Anyway, so glad I saw you video and introduced to your product… I will definitely give it a try!!! Thank you for your post!!
Hello David, Thank you for the comments. We are in a back order situation for the spray foam. Raw material shortages and labor shortages at the plant. Mid August is our target for getting additonal product. Please stay in touch, what you intend to do is within the capability of the spray foam. Thank you.
There you go, you answered any concerns I had regarding the longevity of foam. I only wish I saw this video sooner. I had a similar problem at a location and not knowing of your product went the harder way of jackhammering the slab and removing and doing a new driveway.... If I only knew!!!!
Hello Ron, Thank you for taking the time to post. Concrete work can be backbreaking, maybe if you have something else come up or a friend might have a need, please contact us. Thanks again!
Yours be better job
Awesome demonstration! This is on my pipeline for this spring. My concrete hasn't settled more than a 1/2", but I am thinking I'll do it as a preventative project to offset settling and ant work. Thank you!
Hello Functional ! You are welcome. Please let us know when you want to kick off your project, we will help you all we can. Thank you
@@SecureSet-Fence-Installation awesome, thanks and keep you posted!
I would be concerned that I had drilled into a poorly located pipe and was now filling my bathroom with expanding foam!
Great video showing how not every job goes according to plan and you need to adapt.
Hello Desparky, The water mains are on the opposite side of the house. There is no possibility the foam could travel 90 feet, selectively find the bathroom, force the concrete foundation slab to crack exactly under the bathroom floor and then fill the bathroom. I understand your concern, however what you are concerned about is not possible. Thank you.
@@SecureSet-Fence-Installation Sorry, perhaps my sense of humour was lost on that one. Anyway, I was more considering drainage than water mains.
Cheers.
@@desparky Hello Desparky, Thank you No Worries
For "weights" how about some 2x4 bracing from the top of the garage door? Takes 30 seconds to put three in with a bottom plate to hold down the concrete edge.
Hello, yes that would have been a good idea. Did not think of it at the time, thank you for the suggestion, will come in handy in the future. Thank you
Risk lifting the house? No
Hello Swimming in the Deep, No, the house was far away and the weight of the concrete is far less than the house. If anything, it would have lifted some other area of the driveway long before it reached the house. Thank you
@@SecureSet-Fence-Installation I agree, I was referencing the comment above from another reader.
@@SwimmingintheDeep and you were still wrong. Besides, that was a garage. And there's no conceivable way that that foam is moving that garage.
I bet it would help to get a piece of angle iron and anchor it into the concrete bridging the gap from driveway into the garage that way the slab ur trying to raise will go right where u want it to and not raise up higher than expected. So the angle iron would get anchored from the primary concrete into the garage concrete and anchor another angle iron same way at other end.
Hello Alexstoles1339, Yes, that is a good idea. We have done it on other projects, works quite well. Good comment!
You could run 4-6 anchors with metal straps along the garage floor to hold the “hinge” edge level.
Thank you for the suggestion. GRA Services
Nice job guys👍….…Remember, WATER intrusion usually the main reason why our foundations are sinking especially when the foundation sitting on a nearly flat surface which reduce the water flow quickly away from the foundation…Therefore, foundation erosion starting to happen which weakening the concrete. I think I’ve found the problem on this driveway during the video shooting!! The downspout looks like directed and built within the brick wall and coming down just a foot away from the garage floor. I’m pretty sure if that downspout still there, this driveway will continue to sink! If not, then other surrounding foundations will be copied and eventually back to square one.
Yes, that was likely the issue and was corrected shortly after the filming of this project. Thank you for the comment.
Terrific and honest project, honest pitch and great product. I would buy it! Thank you!
Much appreciated!
I think using a boroscope would be handy for estimating how much foam to purchase and guiding it during the injection process. (Obviously, you'd need to keep the sticky material away from the lens.) eBay has them listed for about $25 that connects to a smartphone or tablet for viewing.
Yes, it would have been handy. We now use an endoscope camera that has a 2 way viewing capability, with a very bright light. It helps a tremendous amount in estimating the project, as well as later figuring out where the foam has moved to and where we might still need to apply more foam. We always wait at least 15 minutes after applying foam to take another look so we don't ruin our camera. Thank you for the comment.
It takes what it takes. You can not estimate wolume in a cavity, no way to measure unless by eye.
Loved the video. Made me see that I can approach my concrete issues myself ...though my voids are very large at one end of driveway
I was waiting for him to say, "See you next week on 'This Old House', with Bob Villa"
Hello Gene, Maybe something like, "Tune in next week folks, with the latest super exciting Spray Foam Video, you never know what ideas people can come up with to use this product!! Best one yet, we refloated a sand dredging barge on the Chattahoochee River!!
Absolutely a great video. So helpful and you two work together so well. Great teacher and great listener. Best way to teach. I’m going to hopefully try this on my backyard sidewalk to my garage and the sidewalk in front of the house that’s not level from slab to slab and chipping away on a couple spots. Thank you for this video and keep up the great work

Kudos to Leslie❤❤❤
Thank you. Real life, stuff happens. Sure ready to try this on my drive! Hope will save having to hire Pro Lift Co. and satisfaction of DIY. Finally some products on market for DIYers!
Hello Foxtrot35, The product is pretty straight forward. Let us know when you need to order, if you have any questions on your project, we can help. Thank you
I watched this entire video, thanks for sharing. I have a breezeway connected to another brownstone however the 3 large slabs of concrete leading into the breezeway have settled and pitch in the wrong direction towards my home, causing rain water to pool during extreme thunderstorms. In turn the pooled water seeps down into my foundation causing my basement to flood. I’m hoping that this product will work well enough to raise the concrete slabs within my breezeway giving me the desired slope to have water roll away from my home.
Hello Jean, If the concrete slabs are not cracked extensively, Secure Set Spray Foam should be able to do the job. As you can see from the video, it does take an effort to plan out and inject the foam. However, I know we have raised some very large slabs and brought them to the desired pitch. Also, since the foam will be expanded under the slab, and since it is a closed cell foam, it should seal the passageway the water is taking to get into your basement. We are currently on back order for the spray foam. Raw material shortages and also a reduced work force to operate he plant. Hard to get workers to come back since they have been living on all the government subsidies. We are expecting to have product again by the end of the first week in August. Thank you.
great video, a real learning curve when things don't work to begin with.
Glad it was helpful!
This video was uplifting
Hello Mana, That might have been a Tongue-in-Cheek but non the less, it was very rewarding for Leslie and for us to be able to video the process. Thank you,

good teacher.
good offsider.
good camerawork.
Much appreciated!
I had a friend in MN who bought a brand new house. The next summer a section of her drive had dropped an inch. The next year it had gone down 2 more inches. She called the builder and they patched the drive. The next year it had gone down 4 inches. They dug down to see what was going on. It turned out there was a gap in her sewer line. She took the contractor and the city to court (it should have been inspected, but obviously not).
How old was this house?
The house we worked on was 18 years old. Is this what you wanted to know?
Wow …I learn a lot from this video…
Thank you 🙏

Audience, Great DIY video for a home owner like myself🤜🏼🤛🏼🙌🏼.
Glad you liked it!!
By cutting a expansion cut were the crack was it might of been the solution for lifting the concrete maybe?
Hello FT, Very good observation! We actually ended up using a sawsall to cut the packing out of the expansion joint to reduce the friction between the two slabs. Once we did that the concrete moved much easier. Good eye, than you for the comment.
You go left right, let the rise on the left and the lesser flow to the right create a void on the right side. Then fill the right and it will lift the right and create a void on the left again, go back left and repeat. Filling up the left and trying to pump more into the left will not work because there is no space unless you lift it, so lifting right creates more space. It is a problem if you fill up the whole space and have tight foam everywhere, you do not have any voids left to lift and create voids in the original space.
I love how well you explain what is being done.
Hello Angie, Thank you very much. Leslie was also very good to insist on doing most of the work herself!!
Water runoff must pool around the middle of under driveway, or at least some time eh? The corner by garage door frame trim to the left looks like newer concrete repair . But rule of thumb is water don’t lie. Whether gutters need looked at , cleaned or directed a certain way and or our concrete guy had us add more dirt around edges and under where it was high and we had tiny access.. rodents and such can dig tunnels and burrow under concrete too.
Hello Johnny,
Hello Johnny, Much work was accomplished during the project and also post repair. Gutter and downspout direction changed was the biggest issue. All in all, it turned out well. Thank you
@@SecureSet-Fence-Installation nice.. we had to do our house driveway, stoop and sidewalks cause they were all sunken and a mess. It was a foreclosure though and sat empty for 3 years. Luckily we have a friend who did it all for $500 and guaranteed for 2 years. We’ll have to do it again soon. Then they’ll have to reseal the gaps too. But it’s a must or can lead to worse issues. Nice work 🤙🏽
EXCELLENT ! Thank you. ( eye protection... ? )
would it be worth the time and effort to try and slide a visual inspecting camera in the hole to see the extent of the voids?
Hello MollooRelax, YES, we suggest the Depstech DS300 camera. Very good tool and can be purchased online for about $90.00
This video makes it look so simple, I hope it's this simple in real life! Want to come do my house next? ;)
Thanks! Some projects are simple and some are a bit tougher to do. A lifting project is dependent on getting all the void space filled, then overfilling in order to get the lift. Many times the path of least resistance for the foam is to find escape routes down a hill, under other slabs, sometimes it even pops up in the yard, and it will also compress soil, which makes more void space. Understanding these types of things and figuring out the best way to alleviate the issues that you can, will help in the long run. Good luck with your project, if you decide to give it a try. We have thousands of customers that have had great success with their projects.

I think cleaning out the expansion joints would have been the first thing to do before using the product. Good product though.
Hello Bob, You are correct, we did have to clean the joint, realized the friction between the two slabs was too great, used a sawsall to cut out the packing between the slabs. Good eye! Thank you
I wouldn't clean the joint. Best course would be to use a diamond saw to cut through any debris, forming material or sealant in the joint to eliminate friction between the slabs. Any joint filler remaining would reduce the tendency of the foam to escape to the surface before the void is filled and/or slab lifted. Once the slab is lifted, then I would clean the joint full thickness, or to hardened foam, install backer rod, and caulk the joint with Dowsil concrete sealant.
The side of my stoop outside my front door and small patio area are sinking toward the exterior wall of our house. Would this system still work?
Hello Mark, We have done many stoops and patios. The issue generally boils down to this; why did the concrete sink? Most often it is because there is a void under the stoop or patio. Determining the size and location of the void is the first step. I always hammer sound the whole area to try and determine as best as possible the location of the void. Once you do that you can respond back to us and we can go to the next step. Thank you
I would like to try this but I fear my garage driveway is too complex. Mine is sinking unevenly due to a huge tree that used to grow where my drive way and garage was later poured. I'm thinking it would take a ton of this stuff to raise it, but maybe not. The tree was cut down around 1955 to 1965. The concrete was poured about 1980.
Good job....thanks for sharing your Secure Set project and procedural tutorial
Glad it was helpful! Thank you for your positive comment. GRA Services - Secure Set
I wish that I had seen this video a few years ago. I had several 2” slabs that became uneven after a tree rootball decomposed and rendered my backyard unusable.
We have many customers that have had that same problem and all types of slabs sunk, including their garage/driveway and even their house slabs. Sometimes they will jack up the slabs mechanically and use our Secure Set Spray Foam kits to backfill for the support, or in many cases they will slab jack with the kits, as well.
Thank you for watching. GRA Services - Secure Set
How do you know when to stop dispensing so you don’t over do it?
Just what I need
Thank you
Thank you! We now have 2 size kits available. 16.6 cu. ft. kit will support 5,040 lbs. per sq. ft. and the 10 cu. ft. will support 10,080 lbs. per sq. ft. Both will lift the same, just consider what you need your final support strength to be. If we had the 16.6 cu. ft. kit back when we did this video that would have been the kit we would have used, since it still has plenty of support strength for most residential driveways and has 66% more foam to work with for the same price.

@@SecureSet-Fence-Installation thank you
Not quite what I was expecting either.
I think that adding a continuous drain to this area would be very wise. Filling these huge voids under the slab might not have been the best idea, the water may now seek a more destructive path, such as under the garage floor or undermine the garage walls.
The drainage issue was corrected after this project and is no longer draining under the driveway. Why would you not want the huge voids filled. If not filled and corrected the slabs would eventually fall further, crack, and probably separate, causing even more issues. Now there is a support strength under the slab of 10,080 lbs. per sq. ft. This is a big win!
@@SecureSet-Fence-InstallationThe poor drainage was not because of the driveway slab, it was due to a lack of a proper drain and stone aggregate underneath the slab.
The foam injections may fill voids left from the water but it will do nothing to fix the original issue, bad drainage. If anything it could cause the water to seek a new path under the garage, causing much more extensive and expensive damage than before.
The best fix would be to remove the slab section , dig the dirt out and fill it with crushed stone (road base) and a semi-perforated drain pipe to quickly remove water from the soil. Lastly, pour a new section of concrete and ensure it has the correct slope and surface drainage.
Using French drains around the footings of any structure is a wise idea to remove water from the soil and prevent water from undermining what is above it.
The foam product would be fine for other applications but not this scenario. Water will find the path of least resistance, it will just flow under or around your foam, washing the soil away in the process.
Once you have the slab where you want it, how do you finish off the project? Do you cap the holes with mortar? How do you clean off all the overfill?
Hello R Myers, Once you are finished, use your drill bit to remove about 2" to 3" of foam from the injection holes. Then take a small amount of concrete mortar and mix it up, then gently pack it into the holes. Then take small fragments of either crushed rock or concrete, (I like to break up the small stones or concrete pieces with a hammer) put the concrete grains on the the top of the mortar. This will help blend the mortar color into the existing concrete. For any overfill, use a heavy wire brush, (I like the one I can use with a power drill) and remove all evidence of the foam. If still have residue or a stain, use some spray can "brake cleaner" and that will help with the cleanup. Thank you
Amazing repair
Thank you for watching our video and commenting. It is an amazing product and can be used for many projects, such as this one.
You didn't mention how long to wait after the 1st " base injection " to re drill, re inject & lift
It all depends on how deep the void space is / foam thickness. It starts to harden in 2-1/2 to 3 minutes (crusting over and stops expanding). We usually wait about 17 to 20 minutes before drilling back through the foam. Thank you for watching. GRA Services - Secure Set
The easiest and best thing to do is remove that small section of the concrete apron, FIX the base, then repair the small amount of concrete slab. Would be a permanent long term solution m, amd inexpensive DIY
That is definitely one way to correct the issue, but this is an "alternative" way to approach the issue and many people have appreciated our product for this type of project with GREAT results. Thank you for watching! GRA Services - Secure Set
I’m just curious, what the cost would have been to remove that 9ft section and pour new concrete. I looked up the cost for the concrete lift. $500 per box.
Thank you for watching. I believe the bid to replace that section was $2,700. That price didn't include any fill dirt or gravel and compression work. Also, since this area wound up taking 20 cu. ft. of foam, they had some big voids that likely went under the adjoining slabs, which now also has 10,080 lbs. of support strength in those areas, as well. When replacing just small sections of the slab you wouldn't be able to get the packing of voids under those other areas without more concrete tear out. Again, thanks for watching and your question. GRA Services - Secure Set
How much does that foam cost? So many holes do u think the concrete will be prone to cracking ?
I would have put a probe a camera down there first to make sure its wasn’t sewer lines not causing that soil dispersement before drilling deeper or filling in foam
Please check the pricing on www.secureset.net. We haven't had issues with the concrete cracking after the drilling. It's very similar to the drilling for the termite treatments, but we don't place the holes as close together.
An endoscope camera is very helpful for many projects, but this customer knew they didn't have sewer lines under the slab.
How can I buy this product?
Thank you for the question. Go to www.secureset.net to order or call 405-672-8885.
Great video
Thank you, we appreciate your comment.

Thanks for sharing. Great work.
Thank you very much :)
It would be great if you could use the safety equipment as suggested on the box.
Yes, we started with safety goggles but removed them because of the heat and the video project.....but as everyone can see from the foam blowback possibilities it is a very good reason to wear them at all times. Thank you!
A face shield is good for that situation. It has much better airflow so it's cooler to wear.
@@vballjim01 Yes, that is a good idea, as well.
I wonder if the pool is leaking and washing away the dirt....
Hello Luke, As it turns out, there is a rain gutter on the inside of the brick wall that empties at the bottom of the wall. This allowed the water to pool up behind the wall. The water exits the area behind the wall through the small hole at the base of the wall. A poor design. This allowed the water to find its way under the concrete. That problem as well as the lifting of the concrete was addressed. We have had heavy rains this spring, no pooling of rain water and no issues of under slab erosion. Thank you.
Could the lift have benefitted by having slant drilled the holes as opposed to having drilled them perpendicular?
Not sure, we haven't tried that. Thank you for watching.
Do you have a video of spraying foam into a wall to aid old bat insulation?
Hello and thank you for the question. We do not have a video showing the Secure Set Spray Foam being used for insulation, but it definitely can be used for that purpose. We have a new kit available that is called our 200 kit (200 BD at 1" of thickness) which is a great insulation foam and can be layered as 1" thickness twice for an RV value of 6 per inch. Go to www.secureset.net to ALL PRODUCTS to see our 2 available spray foam kits. If you have other questions you can give us a call at 405-672-8885. Thank you, GRA Services.
Cost affectiveness..had this been a one kit job...(plan for the worst-case) good deal, but 2 kits ($1000) You would have come out about the same as if you have someone come out removed pack and repour that section and even have an option of putting a drain to solve the runoff problem and no holes or cracks in you concrete...
Actually not, based on bids for the concrete replacement and the necessary fill that would have been needed just in that area. Then because the foam found more places to run to and fill than we necessarily expected, now there is great support in those other areas. The drain was later fixed; therefore, no continued issues. Thank you for watching. GRA Services - Secure Set
Did this over 30 years ago but it was with mud. It was called mud jacking
Hello John P. Yes, a significant evolution in the process of lifting, leveling and filling voids under concrete. Thank you!
Maybe by cleaning out the joint it would have let the slab raise if the joint was tight with cement the slab would pinch against and basically trap the slab.
how many feet away holes from each other need and whats size of drilling hole for injection?
We use anywhere from 1 ft. to 2 ft. apart, it all depends on the project and the depth of void space found under the slab. Use a 3/8" drill bit, and cut back the mixer nozzles about 1/2" to allow for better flow of foam, then wrap black electrical tape under the flares of the mixer nozzles about 6 to 7 rounds. Make sure they fit tightly to not allow for any blowback of foam. Thank you, GRA Services
Hi Just a question here... Would it be better if Leslie was off the slab to be lifted and working from the fixed / level side? Cheers John
Hello John, A comment made by others. It would help a little, but seeing that Secure Set Spray Foam can lift and support up to 10,080 lbs. per square foot, her weight was of little consequence. Thank you.
I had poly raise out to look at my garage that has sunk 3 in on one side they didn't want to do it. So looks like I'll be doing this. I'm thinking on drilling holes near the crack in the center "hinge point" and put some foam there before digging on the foundation and putting bottle Jack's under and slowly jack the garage up and then spray foam under using the pvc pipe on the end like your other videos. Or do you think just drilling holes threw out the slab and raising it like this video would be better? Reason I was thinking on spraying foam on the hinge point first is because it seats a little lower then the other side of the slab so if I bring up the wall side the hinge point would be lower than the other half.
Hello 69Mustang, One of the reasons the Poly Raise company did not accept the job, is because they know it will be difficult to give you a quote with so many unknowns about the project. Your decision to raise your floor with a bottle jack (or jacks) is a good decision. A word of caution about the bottle jack. Use something on top of the head of the bottle jack to disperse the lifting load as much as you can. A customer had a project late last year where he tried to lift everything without a decent size of flat metal or something under the slab to disperse the load. He ended up breaking the corner of the slab. At any rate, jacking up the sunken area, and then spraying the foam into the void affords you a greater success for permanently fixing your issue. The expanded and set foam will support 10,080 lbs. per square foot. The kit will deliver 10 cubic feet of expanded foam. Once you have the corner lifted, you can estimate the L x W x H of the void to calculate the size of your cavity. Thank you
@@SecureSet-Fence-Installation thank you for your response!
Call A Mudjacking company in your area. I Mudjack a lot of garage floors that poly foam companies come out and try to lift but fail because there’s a void under the floor and the foam cures before the void is filled to be able to gain pressure to lift. On average I use around 2-3 yards of material.
@@SaltySeaDawg125 mudjacking only lasts about 7 years, and is rather expensive. High density foam is going to be there many more years.
In hindsight … would it have been just as easy to get a landscaping contractor to jackhammer and remove that sunken panel, stabilize the subsoil, re-pour concrete, and use attractive top finishing? While at it, the concrete crew could install proper grating and drain to guide water in a better way.
Actually she had a price for doing just that (with unknown amount for the back-fill product and labor) and this was the least expensive way to go, even with the extra kit. Also, they did have the downspout issue corrected, as well.
Thank you for questions.

I would take out that worthless section of concrete and install a proper pipe for the water and then pour it in the proper thickness with dowel rods into the concrete slabs on each side the reason why it didn't sink on the garage side is the concrete shelf from when the garage was originally poured
Thank you for your comment. That would be another way to fix the issue, I'm sure. But, this customer decided not to tear out and repour the concrete, and it is working just fine now that they had the drain pipe issue fixed, as well.
Very informative...thank you
Glad it was helpful!
Thank you for watching.
Thank you very much . I have same problem in my driveway.
Hello Mark, If you need any advice, please email us some pictures an we can help you as best we can. Thank you. email: info@graservices.com
what keeps the foam from compressing over time, with driving over it seems like it will compact.
Hello Jerry, The foam will compact if and when the combined compression weight of the concrete and the vehicle exceeds 10,080 Per Square Foot. No standard vehicle combined with the weight of the concrete will exceed that value. Therefore, the foam will not compact over time. This is not like the spray foam in a can. This is a closed cell, high density foam. Thank you
did know about this product. will have to use when the time comes. but i guess safety glasses is optional, considering all the drilling and the possibility of getting sprayed on your face.. LOL
Safety glasses are highly recommended and says so in the instructions and safety data sheets inclosed in the kit. We started with them, but chose to remove when filming, but should have kept them on, for sure.
How long does the foam last? I have a slab that keeps sinking after I have jacked up the concrete and filled underneath with crushed stone and cement several times in the past 15 years or so. I think because I live near Lake Michigan on sandy soil (you hit sand after about 2 feet or so), I will near get rid of this problem ...
Thank you for your question. High density foams are expected to last 40 plus years, since nothing dissolves it and it has no nutritional value, so insects don't feed off of it .
My only question is how well does it hold up over time
This type of foam is expected to be there 40 plus years, since nothing really effects the hardened foam besides intense fire.
Is it has better pressure than can spray? And what is adventage of foamjacking than just use self level mortar?
Lastly, sry for lots of questions but I thought the foam harden under slab at the first job. How it keep going even they trying after foam harden. Because I couldnt see under slab it is hard to understand because commercial foamjacking was lift slab at once
Hello Nopark, You have good questions, here are the answers: 1. Does It have pressure higher than can spray? Yes it does, the twin cannisters are pressurized to 180 psi. If you needed to, you can shoot the foamed spray about 6 feet. 2. What is advantage of foam jacking over the use of self leveling mortar? That type of mortar is primarily used to patch or pour concrete floors. Because it has a slightly lower viscosity, it will settle to the lowest point and flatten out like a pool of water. It is bot meant to expand and fill voids. 3. How does it keep flowing even after some of the foam has hardened? The foam, once it comes out of the nozzle, will expand and move to the closest void. Adding additional foam will force the foam to flow around any other foam that has hardened as long as there is a space or void to travel to. 4. Commercial foam jacking will lift slab at once. Foam jacking is used just like our foam to fill voids and lift slabs of concrete. The foam reacts and flows to the point of least resistance just like any other foam product. It does not happen, "all at once", the foam has to fill the available voids and spaces first, then it will lift the slab when the foam has no where else to go. Thank you
@@SecureSet-Fence-Installation I appreciate about your very kind detail answer.
nice video, does anyone know what is difference between the secure set and great stuff foam ? secure set more tough and load bearing more weight ? thanks
Thank you for the question, since a lot of people aren't familiar with the differences in spray foams. Secure Set is a high-density, closed cell, commercial grade spray foam. This kit we used was a 10 cu. ft. of 4 lb. density foam with a 70 psi compressive strength, which means it will support 10,080 lbs. per sq. ft. This foam will not absorb water, get spongy, and flatten out like Great Stuff. At times, we also have another commercial grade foam that is 16.6 cu. ft. kit and is a 2.8 lb. density, which will support 5,040 lbs. per sq. ft.
Can you suggest a product to fill in the drilled holes in exposed aggregate concrete? Thanks for the great video!
Hi Jonathan, you can use any concrete mortar or concrete patch product on the market. Also, we like to save some of the concrete dust from drilling and use it on the top of the patch to help match the old concrete. Thank you for the comment that you enjoyed our video.
Would making a couple drill holes on the other side of the concrete next to you and see if there is a void on that as well?
There very well could have been voids there, but hammer sounds didn't indicate that there was.
There was definitely voids traveling down the driveway,which is probably where some of the foam went. Luckily that has all been filled now and the water rerouted, so no additional issues.
Thank you!
