I am a mason for over 35 years and what you did with the pool noodle isn't a bad idea especially with the crooked Crack because the noodle is flexible, but I would suggest using quick-create, just mix with water, it's premixed cement, just add water and mix. Then use a small hand garden shovel it in, push down on the cement to get gaps and air pockets out of the cement. When cement gets to a putty type concestansy take a large damp sponge and run it the length of the Crack and feather it in to both sides of Crack, you can do it with the stuff in the tube but you sill have to feather and level the product that comes out of tube
Yea mate thats good mail , also if it’s a hot day wet the concrete down first so it doesn’t suck that mix too quickly .
@@queenslander954 Good call, give both sides of old concrete a good dampening if it is a hot day👍
What's feathering
@@krazyboutkeekee92 Feathering is moving the new cement up against the old cement, like blending it to the old cement,usually done with a tool called a hand float, but in a homeowners case most likely would have such tool, take a large sponge dip it in water and ring it out so it is just damp and blend it up to old cement, the most important thing is to make sure rain water or sprinkle water does not get into the old Crack. Now it depends on the climate you live in, if it freezes in winter you don't want water to get into repair and sit and freezes, it will Crack. That is the best I can explain, feathering is just blending up to old cement, good luck
Thank you! I was looking for a solution that doesn't involve any plastic!
Nice presentation. Having done this job on a windy late-fall day, I appreciate your thoughtful sand idea. Tiny leaves swirling into self-leveling goo is a nightmare.
THANKS!! I've had a large crack in my concrete patio for 25 years without EVER being able to get it fixed but NOW I'll be able to do it myself!!!!
did you do it? How did it turn out?
I found this video by accident looking for something else and I'm glad I did! I have a large crack in a sidewalk that I had filled several years ago by a mud jacker. Didn't last only 2 years. Also 2 sections of sidewalk have spread apart and garage floor and driveway have split apart. Should be easy peasy fix for An 84 yr old woman by herself to do! Thanx!
Did this work for your sidewalk plz?
I wish I had known about this long ago!! My dad’s electric wheelchair had a hard time going over gaps, caused by tree roots, when going to our wheelchair van. Sometimes the ramp would settle on a crack and not sit level. This caused the ramp to tilt when he drive the wheelchair into the van. The cracks in the sidewalk were also large and hard to get across. These were situations that were a serious tipping hazard. Sadly, Dad passed away two weeks ago. He’d have approved of your fix. He had ideas like this, too. Thanks for sharing. I’ve subscribed and look forward to more helpful information.
There's a quite satisfaction in seeing a problem get fixed while learning at the same time. Love these types of videos.
Good video thanks……be good to your knees tho…✌🌻
I don’t even have the problems you fix most of the time, but you’re so engaging to watch, I watch them anyway.
Thanks for the support 👍
EXCEPTIONAL tutorial video - so clear, concise and straight to the point! I love the way you cover every little detail, including warning what to do/what NOT to do. You make it look so easy, even I could probably do it. Therefore, I have liked, subscribed & clicked the bell. I will be following you along your journey, so keep up the GREAT work, Scott. U THA' MAN!!!
You are such a great professional 👏 at teaching people the way to fix problems that bug us as we pass by that crack everyday. 🙂
I cannot tell you how many projects around my house that you have given me the confidence to do. I really appreciate the information.
Great overview! I've done several of these repairs of irregular cracks using spray foam to create a backer, which is not as easy as it sounds. I've needed to carefully carve down the foam to be below grade, so I get a clean installation of SSL. I'm going to use the pool noodle next time!
Hello 👋
THis is wonderful! My family and I got a new home and I almost tripped going up the stairs. I definitely will do this to fix the trip spot. Thank you!!!!
The doubled-up duct tape at the edges and sand sprinkled on at the very end were each a nice touch.
Great Video Scot, sprinkling the sand in at the end way a genius idea!
Thanks bro 👊
It genius for more cracks. Conc needs room to expand. Putting sand in the crack does not allow this. Incompressible. Otherwise great video
@@adbates 😂😂you think the pool noodle and caulking will stop the sand from being pushed vertically. Carry on.
@@adbates what?
Great idea!! I have multiple cracks on my screened-in back porch concrete floor. Your method should work there too. Thank you so much for sharing.
Thank you for your kindness! People like you make a positive difference in our society!
Man, that was genius. I love the way the sealant is liquidous and self levelling. Neat job. Thumbs up for me.
Good stuff, you cant rush the early steps.
I had a boss once that saw me half assing something he said " You do all the steps or you will be stepping to another job" .
Never forget it.
Thanks for this! Not nearly as much information for large ragged cracks...just the small ones. Gonna buy the materials tonight and get going on my old patio tomorrow! Very clear video!
So thankful that I've come across your channel, I'm learning how to care for my home and this video was so helpful! Tfs.
This is a pretty elegant solution. I owned a home where the garage slab cracked and had I known how to do this, I would have. This is a 100% solution versus using patchmaster to fill the gap which in hind sight was a 50% solution.
This is nice and I’m glad you showed the trick of sprinkling the sand on top which definitely makes it blend in better! I’ve seen places that were caulked w/o that step and it looks terrible and sticks out like a sore thumb.

I wish i knew the sand trick when i sealed a crack in my walk. the lighter sealant really sticks out.
If you use the sand on a crack instead of a joint people tend to bring the caulking to the top and then add sand. The patch will then be higher than the cracks. Make sure you leave it down from the top just a smidge if you are adding sand. I personally dont care for the sand look but its just a preference.
I saw a man fixing and patching someones front steps and he got some dirt and mixed in for it to look more like the old cement he was patching!! not a bunch but enough to take away the "new" look, and it worked!
@@therebellion6911 Hi. What’s the difference between a crack and a joint? Meaning, even if you do a joint, aren’t you supposed to leave the sealant slightly below the concrete to compensate for the sand as well? Thank you
I really appreciate this video! I've tried filling a growing crack in cement with wet cement and dry cement at different times and neither lasted. This is the best, affordable solution in my opinion. Thanks so much for this!
I have 1/4" to 3/4" gaps in several spots. Already had my backer rod. Didn't know what to use for a sealant. The SSL sealant was the final step I needed. The sand topping was a bonus. Great video....thanks. Happy 4th of July.

Carefully explained & clearly demonstrated, with just the right amount of speed-up, and NO CHITCHAT OR MUSIC. And important info about drainage issues in freeze-thaw climates. Thank you!! Instead of the drill attachment, a wire brush would also work, right?
Very nice results - looks great! Will be using this repair on sidewalk at an apartment complex.
Heh would you consider showing us how you keep your tools and material organized? Earlier I noticed your tote for electrical connectors. Thinking I need one just like it! For those of us that do sidewalk, yard drainage, electrical and plumbing all in the same week, how to keep everything organized!
Awesome channel for DIYers and multi-trades maintenance folks. Thanks!
Use multiple tool bags. 1 for plumbing, 1 for electrical, 1 for general maintenance, 1 for patching/painting/minor carpentry repairs
I also use plastic 5 gallon buckets to help out. But yeah it gets crazy!!!
Using a pool noodle for backer rod for cracks is absolutely great thinking. The thickness of the calking is critical to making a successful repair. . Read the information on the label to find what that is. To create that consistent thickness, I use a scrap of board with a wooden spacer tacked on it and run it the length of the backer it pushes the backer rod down to the correct depth consistently. When the calk is too thick it doesn't stretch properly and will pull away from the concrete and the joint still leaks.
OMG! I just used pieces of a pool noodle to help fill in a crack last week. Worked like a charm.
Thank you so much for this solution. I have been trying to figure out how to fix a patio crack in my house. God bless you.
Nice video. You could use water pipe wrap. They have 1/2, 3/4 and 1" tubes at your local lumber yard.
Never would have thought of that - great stuff, Scott!
Thanks Nils 👍
Boy...you are a magnet for cement issues! Finally...someone pickier than me...Cool Vid!
I bought an older home and there are a lot of these crakes, this looks like something I can do myself even with my achy old body lol. Thank you so much.
Go with low expansion urethane instead of baker rod. Applied gently with cleaning off the excess after 20-30 min (time to get ready for next step) You will then start to use urethane for almost every gap/void/volume filling inside or outside. Very nice talent that God gave you. You're definitely giving good fruits with all your videos. I like your humility and your hardworking being.
For a more substantial joint, I pack the seam/crack with pea gravel to about half inch depth from the top. Then fill the joint with the joint filler. Much less likely to pop out or be "ejected" due to ground movement.
If you do not fix the problem which caused the crack, there will be trouble on the horizon. I am fixing cracks at our mountain property using an asphalt based Lowe's product, but filling most of the crack with gravel first, then topping it off. Not perfect, cannot be applied too thick at once and it requires going back over more than once after drying in. This guy's method does not look as good for what we have but then none of our gaps are as large, so I can understand that his problem requires a different solution.
@@replyhere590 thanks. The joint filler i use between stones is a flexible epoxy type and it seems to move and stretch somewhat without breaking seal
Now that is thinking outside the box!
I would have never thought of using a pool noodle like that.
I also would not have thought of putting some sand on top of the sealant! Also brilliant!
Excellent idea. Absolute genius! Using pool noodles to fix cracks in a concrete sidewalks. Using pool noodles in your yard is definitely better than letting all those pool noodles get into the wastestream and thus threatening our precious natural resources.
Omgoodness thank you for the step-by-step tutorial I'm sending this to my landlord.
Much Thanks...

B😂😢 I just got at 😮😮
Hello 👋
Wish I’d seen this some years earlier. I have concrete steps with a massive crack that goes always through. I filled it up with spray foam, not the best fix but it keeps the wasps out. I’m going to rework the crack using this method. Thanks.
What a neat idea! We have lots of cracks to fix and can try this method before tearing it all out and hiring someone. Thanks
Best DIY video I’ve seen for this type of job - thanks!
Awesome way to repair! Quick and concise.
Awesome step by step tutorial. Thank you for the info.
Excellent tutorial! Thank you so much for sharing this.
LOVED IT and if you have a chance, show us what it looks like after a full season...awesome
I'll be doing this soon. I was planning to apply a light dusting of cement atop the sealant. I think it would be a better color match than sand. Or is that a bad idea?
Thank goodness I found you! I have to take care of my home on my own. I wouldn't know some of the pitfalls if you didn't express them. Although I can understand "semi-leveling" v "self leveling" Unless you explained what happens in this instance, I wouldn't understand in its practical usage. Same with the duct tape. Wouldn't have thought to cap the end like that, and if I did....I wouldn't have thought about the caulk sticking without you adding that in. Those 2 things would have made this a fail for me. So thank you so much!
Happy to help and thanks for all the great feedback 👍

Very cool, I'm also a crafter so I always have the pool noodles! I also learned from another channel who uses this & foam in his monster props, that you can use a heat gun to make the foam stick/glue itself together if you want to 😉
@Vro - you use a heat gun to make the foam stick to what exactly? Thanks
@@bethanyanderson1745 You can shape it, stretch it, stick it to itself, check out Stiltbeaststudios pool noodle pumpkins. He uses pool noodles, foam pipe insulation all the time & learned the technique from him.
@@Vro- - thank you for replying. I'm not a handyman so perhaps that's why I'm not seeing the connection between filling a cement crack and heating a pool noodle /foam.
For a smaller crack but still large enough that it would need a lot of sealant, I had good results stuffing in pieces of or whole corks saved from wine bottles that I had on hand, then sealant over. I like the suggestion of putting sand in deeper cracks.
What sealant do you use?
That's a very creative way to utilize a pool noodle!! Great video, thanks!
we used to buy that backer rod in 100ft rolls in about 4 or 5 sizes to pack around window and door frames before sheetrock went up. Some builders didn't like the expanding foam. They said it bowed the frames.
Never thought about filling cracks this way. Thanks for the video!
Does the San Andreas fault run through the middle of your property?
Hahaha, no doubt. Just picked this place up a couple weeks back and this part of the entry was a bit rough.
my guess is tree roots and / or expansive clay soil
You'd be surprised how many fault lines, both active & ancient, run thru the Midwest. Even Minnesota has a fault line. The Great Lakes Tectonic Zone runs from Big Stone & Traverse County to Duluth and while not very seismically active compared to the San Andreas, it has produced some decent "I felt that"-type quakes.
My house is right in the middle of the Cascade fault line.
@@ytsux9259 You must live close to me.
Wow, you did a beautiful job.....so neat and looks just great when you finished. Great video! 👍👍
Awesome! Thanks for your video. I’ll fix our concrete walkway soon.
Essentially a large size foam backer rod. My Grandfather used to use the tiny backer rods to fill sidewalk cracks followed up with some sort of concrete compatible caulking. I'm not sure what he used but his repairs would often last more than a decade. I could probably swing by his home that he lived in long ago and built in 1986 and they'd still be there long after my Grandfather has been gone.
What I do is, clean as he does, dig out all the debris in the gap (as deep as the concrete is) then tape over the edges and fill the gap with waterproof expanding foam. When that dries I use a wire cup bit on a hand drill to remove excess foam to about 1/2" depth. Then finish up with self leveling sealant caulk.
When you say you tape over the edges, do you mean the cracked edge of the concrete? Does the tape stay in place after the entire repair is finished?
cool idea!
@@annfraley7083 ... Before I apply the expanding foam I mask the edges of the concrete, the top surface. I use 2" painters tape so if there is any over expansion of the foam it won't spill out over the top surface of the concrete. Once the foam has dried, it's easy to break off any excess foam before cutting/grinding out the top 1/2" or so of foam.
I think I might like this idea better as I'm not very good with my hands, and I don't think that I would cut the pool noodle as well as he does. I would probably end up making it look worse than it already does lol. But I liked all the other things that he shared in the video
@@digiacomtech5589 Won't a stiff rotary brush on a drill or grinder buff off any excess foam, overall more quickly than taping as you describe?
thank you for sharing your knowledge, looking forward to giving it a try with my DIY's!
This is great, thank you for taking the time to make this and post it.
Or pipe insulation tubing.
(SAME material). Just in case pool noodles are out of season.
That’s what I was thinking. Plus pipe insulation is gray, so if it peeks through the sealant it won’t stick out like a sore thumb.
I wish I had this video 15 years ago. I had a few big cracks close to the foundation of my house causing a leak into my basement. I was able to stop the leak, but not as efficiently as this! So ThankYou for this very informative video!

2 videos in, already see the quality differences. Great Job.
I saw your other video where you filled the crack in front of your garage and liked it a lot!
With a crack this large (like I have in my garage) I may lean more toward quickrete so it isn’t just a thin layer connecting the two chunks of concrete
I love it. The solid concrete will continue to move but with the sand, foam, and the self leveling caulking will move as the environment demands. Where did you buy the self levelling caulking?

Excellent video! Thank you for sharing your knowledge.
This was a very impressive video . Clear instructions. And a handsome instructor.😻☺️
I used a very similar technique to repair concrete walkway, but instead of sprinkling sand as the last step, I used some dry mortar mix. The finished product will more closely match the concrete walkway.
Great idea.
And as I posted in my own comment, I would use a generous amount and simply sweep off excess the next day.
13:20 I've also mixed spare Mortar Powder with the Sand, for repairs like this.
Seem to me that the Powder would harden, and prevent the Sand from washing away.
Well explained and super informative video. Thank your for sharing this. I'll be able to put this to use for sure.
Thank you for this informative, money-saving video.
Great video! Would you use this technique for a gap between concrete steps and the foundation of a house? The gap is quite deep - about 3 feet down to the ground.
No
I love this content. Cracks in concrete are a pain and if you don’t know what to do it becomes a pain one way or the other. Thanks bud.
fantastic idea to use the pool noodle, and easy to follow for DIY'er like me. thumbs up 👍🏻 !
Nice video. Sand at the end definitely helps with mimicking texture of surrounding concrete also
I tried something a bit different. I used Dow expanding spray foam to fill the crack. It dries quickly, then I used the ssl to seal up. Worked great and saved me the time of having to cut and shape backer foam. A word of caution, don't go buck wild with the spray foam, it expands big time.... Whichever way you go, the crack gets fixed....
👍🏻
They make low expanding.
@@therebellion6911 yeah, I had to learn that the hard way.....lol ...
Warning, I tried expanded foam in a concrete (cement) crack and it did not work. The foam gets chipped out and discolored.
It is very difficult to control joint depth with foam. And for the SSL to perform properly the depth needs to be very consistent. And the profile of the sealant will be incorrect. These things matter for the sealant to perform properly.It is a quicker and easier solution but not a quality solution .
Thanks for the tip. Just started following you. I've always been a DIYer and always looking for great tips. Thanks 👍
GOOD VIDEO!! I have a driveway crack which is very shallow as I have filled it previously w Quickrete. I grinded out a nice 1/4" slot most of the way but have shallow sections (where the tires usually impact the pavement). Can I just use the sand without a backer rod on the shallow sections? I already purchased Quickrete Non Sag sealant. Any advice appreciated
Love how you sped through the B.S. and concentrated on the fix
Good idea. Have you tried dry cement at the end instead of sand ? It might help blend better.
This is a cool idea but I've found that using spray foam is much easier as it conforms to every bit of the crack in there and there's no need to make cuts unless you use too much
We have gaps too, Thanks for posting, this will help us!
I see you too have the classic Craftsman sidewalk crack scraping tool! This is a neat fix. Will keep this in my back pocket if it comes up for me
If slabs are at different levels, drill a 1/4" hole, insert the nozzle of Expanding Foam and watch the sidewalk rise. May take a couple of cans but much cheaper than calling in a slab jacker.
or dig a 6in deep hole and use a "car floor jack"
Id love to see this without a void. Any videos? I dont see this happening with a slab sitting tight on the ground. Could be wrong.
That doesn't work with cans of expanding foam from places like home improvement stores. Have to have two part (expensive) foam.
@@bran-qt7ds Wrong. It works with good old fashion canned foam you get at the Big Box stores. TH-cam is your friend.
@@fartpooboxohyeah8611 you really need to learn the difference between how open cell and two part closed cell foams work. Claiming 'i seen it on TH-cam' is certainly amusing though, as if everything on the Internet is real.
You could use an expandable foam vs. the Backer rod so you can avoid going back and forth with cutting the Backer rod to suit the cracks. An even easier method IMO is to use a pre-mix cement screed which you can buy as a dry-mix in a bag. Just add the recommended water and pour into the cracks directly. It does have admixtures that would prevent cracking between the old and new concrete. Trust this helps.
I think I have seen a mason on TH-cam do something similar instead of sand. I think his mixture was 3 parts sand to 1 part portland cement and then he wetted it to the consistency of wet sand. He packed that in the crack. It would stiffen up but remain flexible over time.
No foam or processed chemical adhesives, some crushed recycled construction waste with some cement pored onto them and everything is fixed naturally. Even stones that are around your property, if they weren't naturally formed and they come from construction, or you can buy you any recycled construction waste of the appropriate size , have a bucket for any eventuality and you can always use them as filler or even cast some bricks if you need any.
You could use the expanding foam but pool noodles sell at the dollar store, 3, 4 noodles is going to cost way less
Actually using noodle is better because that caulking form is thinner on middle and wider on side which means thin part flex easier and wide parts sticks well to concrete. IF that caulking is same thickness whole area it can peel of easier.
Trouble with expandable foam is laying a perfect bead down to suit expansion rate. This almost never happens, which means shaving it down - p.i.t.a. The noodle is cheap and bendy: perfect for irregular lines.
For uneven gaps, you can anchor the backer rod with some long (80-100mm / 3-4 inch) stainles steel nails into the ground, so it will not float to the top. You will need more sealant, but as long as you don't need to open another can, you are in the green.
That's a good one, easy, fast, and cost effective. 👍
I’m wondering if you could use fine concrete instead of sand to blend better
As a professional remodeler. Loved videos you have done leveling the cement slab and filing driveway joints. Just wonder why don’t use Quic-Krete cement or mortar which is gray and blend better than tan/brown sand when you sprinkle onto the wet urethane caulk. Again I LOVE your videos, very well spoken
That's what I would do
I have used the smaller foam rope for many cracks in concrete
Nice and useful tips! Thank you!
Great idea. Where do you get the vaulken tubes from ? Also, how deep should the foam go ?
Spray Foam would be the preferable product for those large irregular gaps; cut down, then sealed with the SSL/SL sealant
The spray foam contaminates the substrate and compromises the bond of the SSL. And it doesn’t give the proper joint profile of thinner in the middle and thicker at the sides which is essential for proper sealant performance
@@genecarden780 nope; and yes Spray Foam actually does give proper support and fills the voids, which w/o would allow for further erosion. Spray foam or mud pumped in to fill those large voids is the only right way to do it. And a SSL will not interact with spray foam.
Joints with this obvious amount of movement require primer. On the cartridge it usually says something to the effect of “ no primer required for most substrates” But if you read the material literature it will tell you to prime joints like this. I installed sealant for a living and on a lot of projects we would use thousands of gallons of sealant. When you use these amounts a material rep will show up to make sure it is installed correctly and every time they would say to prime or the material guarantee is void. If you are going to take the time to clean the joint properly ,as the video shows, you might as well brush on the proper primer.
What type of primer is suitable for a concrete surface?
@@billbaillie3702 unfortunately that takes a little research. Every product may require a different primer so it is impossible for me to give you a good answer. But you should be able to find out pretty easily on the manufacturer website. Just be sure to locate the primer for the specific sealant and substrate ( in this case concrete) you choose.This is what I found for Vulkem 45 SSL :Where deemed necessary, use Vulkem® Primer #191 Low-VOC QD on porous substrates You can usually find this information on the material data sheet. Primer is also recommended because even though it is semi self leveling it is still supposed to be dry tooled( something very difficult for a homeowner to do correctly) Most people think that dry tooling the sealant is cosmetic but it is actually to gently force the sealant against the side of the joint to ensure good adhesion.
@@genecarden780 Thanks. I was thinking it would be something Vulkem compatible, I've never seen a primer product available where I usually purchase Vulkem. Are you spraying water or a specific liquid on the fresh Vulkem prior to tooling?
@@billbaillie3702 NO never use anything on the sealant to tool it.That is why it is called dry tooled. Any type of liquid will interfere with the bond. Anytime you see someone wet tooling it is a sure sign they don’t know what they are doing. That is the real advantage of SSL is the tool marks will flow out so you don’t have to be as good at tooling the sealant
