How to Waterproof a Foundation

- We're going to show you guys how to waterproof a foundation. We're going to create a barrier - a one piece membrane that's going to keep out the water. Now our drainage system will handle all the water, but this is just another line of defense and this way you don't have moisture wicking through the foundation. You end up with efflorescence inside a basement wall. Not to mention musty odors.

Replying to your reply from part 2. Static pressure from water pushing in from the soil destroys many membranes after 5-10 years, especially where the ground is wet. In your case you have heavy duty exterior drainage, so perhaps the dimple board with non woven geotextile fabric bonded to it is over kill. You solution even without the membrane will allow very little water to get into that block wall. Block is porous so it will get through.
I really like that you use damp proofing. That tells me a little moisture gets through, and then inward dry into the conditioned space takes care of what little there is. I am always suspicious of "seals", the need to be perfect forever, or else you will water that has no escape hatch.
This house will be more comfortable year round as a result of your work. A dry basement or slab in this case, is highly underrated, as a large percentage of the latent load comes from the basement.slab.
Your crew is like a ballet, I love watching how efficient they all are.
i like that you own up to your honest short cuts like applying when the temperature is too low. damp proofing versus water proofing even though thats the whole point of excavating around the foundation and the high expense. honesty is key. especially if it fails.
All you can do is your best with all the different factors that come into play.
I have a dry basement by following your advice and purchasing your products. Thank you for your videos. Great source of valuable knowledge.
Wow this is incredible. At first I wasn’t sure why the paint was angled. But I see the grade matches the angle. I bought a raised ranch in CT back in May. Basement is finished but there was a flood cut done. Previous owner said the basement flooded and it’s fixed. I think they lied. Anytime we get a lot of rain the basement gets water. This weekend was the worst. I had to squeegee water out of the garage and shop vac a few areas in the basement. Now there’s Efflorescence on the waterproof flooring. But it’s all ruined now. Before I rebuild it I need to prevent it from happening again. It looks like a footer drain will work best. I do need to grade the backyard as it slopes into the house. Problem is we have a deck along the back of the house that will need to be removed. FML.
We have 1500 videos. Go to the "French Drain Man Channel " home page and pick through the many playlists.
Love how much you praise your workers. Excellent job.
Thank you very much!
My pleasure. I've got cinder block one row is below the soil. I've removed it and putting a French drain. Do I put bitumen against the cinder block or can I use zissner water tite or do you recommend another rubber product. Thanks
It goes a long way with moral.
Now, if we could have a video in spanish so other folks can learn. Great job, boss and your workers, fanatstico.
I didn't see the rubber membrane product listed. Would please let me know the name? I have a small project coming up and would like to use this instead of a damp proofing membrane. Thanks for the video. Great work
Nevermind. I found it in the comments. Could you ballpark a price for a job of this sized scope? More than 10K?
polyguard.com/product/polyguard-stretch-flex
Job would be 45k
Would you still recommend the same type of sealant even on older brick foundations instead of cinderblock?
Why wouldn't you seal the foundation before the French drain and all the backfill was done
It was too wet, and we didn't want it to collapse. It's better to backfill with Stone asap
At 26:00 minutes in the video you say you have to dig deep and dig down to the footing and then dig a boot below the footing. I am thinking that you are saying dig down to the top of the footing and then down another foot as most footings are a foot deep. Is that what you meant? Great video and a nice job. Thanks for the knowledge. The school of experience and hard knocks is a great teacher. Thanks for saving us some hard knocks. Will be tackling my son's house come the spring.
Every situation is different. 5 inches below the footer shelf in most cases
@@FRENCHDRAINMAN Thank you sir.
Great video! Planning to do this on my block foundation this summer. What size of bit are you using to drill through the block and whats the size of hammer set anchor?
1 1/4"
Thanks for all this info! What is the clear caulk, applied with a caulk gun along the top of the Delta Membrane? It looks like a tube of DAP Product. Is it Silicone? Thanks again!
Yes Silicone
A good job , but seems an over do ? The same damp proofing can be applied to the inside of the basement or crawl w sprayer !
This house is on a slab with 42" concrete footing under the cold joint
Do you use the Rhinox buckets on your excavator?
Yes
I'm very happy with the aftermarket buckets
I have a few on my vio 17, looks just like yours, and so far they are great@@FRENCHDRAINMAN
Any thoughts on Hydraway waterproofing?
I'd never use it for a foundation drain because iron ochre would clog it. If you want to use it for a yard drain. I could see applications in sports fields and backyards.
What’s the rough est on cost for this project?
45k
I tried ordering parts for my foundation drainage system but the shipping was like 500 plus dollars which was more than the products price.
If you can buy the pipe locally, the rest of the parts fit in a box and don't require a pallet. Price is very reasonable.
What brand and size is that material bucket you have on that sk1550? I’m looking into getting one
I bought them through the Ditch Witch Dealer
@@FRENCHDRAINMAN thanks
@@tractorworkandmore411 check out equipment auctions around you, you may be able to find one a bit cheaper
That’s a lot of work using wire brushes around that whole foundation! Good job on this project 💪
Good work! However, instead of sealing or using a membrane, I would clearly preferred Pordrän or Isodrän solutions. That is insulation with draining. Moisture will go from warm to cold and would then be sucked out of the brick wall, and after condensation would have gone straight to the French drain system! Easier to set up, dryer and warmer walls. Hard to get in Michigan I expect though.
Thank you for sharing
Quit bragging about the quality of work. We can see for self. Vato do the best WWORK!!
love to see you put the dimple board on the right way :D with the dots towards the house :D
That layout remains me of my my house. Bump out, grade being pitched towards the house also. One different is the I have a 2.5 foot crawl space. I have a big job ahead of me. I’m a carpenter by trade and have been on job sights for 30 years but I still don’t have my plan figured out 100%. I’ll have to do a foundation drain and gutter drain but elevations are my enemy. I’ll have to put a pump on one end of it. As always thanks for the videos. I’ve learned a lot
👍
Awesome job! Being on the west coast I don’t see alot of these jobs. Great to see the process done correctly.
I’m impressed

This guy talks too much
Yeah, totally hate hearing a boss be supportive of his workers.
Look at that final grade! My feet felt good just look'en at it ! 😂
Thank you 😊
bfor and aftr very very descriptive on quality of ur work congrates to u and ur team
I was told recently by a respected company in my area (Middle Tennessee) that you can use a subterranean insulation instead of dimple board. I'm not sure of the science behind that or the specs. I think it wicks the water away from the wall and gravity feeds the drain while insulating the foundation. Asking because the dimple board seems to be more labor intensive to install/complicated. What are your thoughts on using the insulation approach instead of dimple board?
I have limited experience with that. You need to do your research to get that right. It makes sense to me that you would waterproof the foundation before applying the insulation. But again, I haven’t done the research; I never do anything blindly. I’m always well-educated before I do anything.
Thank you for your commenting and sharing
Thanks for video
Learned a lot from watching
Could you put rock or French drain system to the top of the simple board instead of back filling with soil ?
That's not something I can support. You need to grade away from the house, hoping not to run the bulk of the water through your system. Also, if the pipe ever plugs, the hydraulic force will push the wall in. If stone is all the way to the top, it brings some hefty liabilities.
You mentioned there was some old sealer on the wall of the house around 1:40 I'm guessing thats the black looking tar on the wall. I've got something similar on mine, but mine actually looks like its peeling off in places. In this case (I'm in Tennessee and it's summer here) can I just pressure wash over it then apply the Polyguard after it's dry? I was going to point tuck cracks with hydraulic cement but can't see any because of this black coating already on everything. Just wanted to double check what the move is. Thanks!
Yes
Just curious why waterproofing isn't done while building new homes 🤔. We know water issues will always pop up at onetime. Why leave it to helpless homeowners to fix 😢
It's extra, and you have to request it. You also have to be willing to pay for it. Most people don't see any value in it. They just want pretty floor tiles, fancy showers, expensive countertops, etc.
Awesome work and narration, what does a job like this run for in 2023??
For foundation drain, waterproofing, grade correction 65k
Should have done one cinderblock higher with the water proofing above the grading.
Home owner than can paint the rest of the foundation with matching masonry grey paint.
Other than that nice job. 👍
Thank you for commenting and contributing. I really appreciate your input.
Should have sealed ALL the block! Otherwise all the lower blocks will get wet from above and won’t be able to dry because they are now sealed.
@garyg8036 Do you ALWAYS edit your comment when some has a better suggestion?
I’ve read that you can prime and paint over top of the rubberized paint. So could you just paint the rubberized paint all the way up the cinderblocks? Is there a reason to not do this?
Hello Robert. I have water entering my basement and I think it is finding its way under the poured concrete front stoop and then underneath the sill plate, then slowly trickling down the basement wall. It is about a 7 or 8 foot section from where my front door is and the front stoop where this appears to be happening. I can tell it is coming under the sill plate because of the dirt being found there too. Somehow this is happening during rain events and snow melt. Can u help? Would demoing the front stoop, putting in a french drain, and then waterproofing with the black tar in that 8 foot section solve this issue? It is not a ton of water entering but enough to cause me concern. Thanks. Subscriber from Philadelphia. 1988 build home, colonial. Poured concrete foundation. I can email pics if u need. Thanks!
Sill plate is a common place for water intrusion. It is hard to form a seal where concrete and wood meet. Use silicone on your porch. It's probably entering behind the slab. I don't believe you need to demo it. Just seal where the concrete meets up to the house. I've also seen where people build up to high on the house
with dirt, and that will cause a problem. Definitely check that all your underground buried downspouts are working properly and that no lines are clogged.
Thank you for being a subscriber.
I hope this helps.
Do you guys travel to the Northwest Ohio area ? Specific Lima, OH ? Just bought a house and know I need to get my drainage upgraded.
South East Michigan. Google "Yard drainage near me"
I needed to see how you put the French drain down...this is excellent advice but I needed to see the drain tile laying down .

Cool video, you know what you are doing and have attention to detail. What is your opinion of the UMINN Hydrovac system where they excavate a 4 inch trench around the foundation then use foam board and pourable foam to water proof and insulate the foundation? This is the link to the You tube video; th-cam.com/video/rNJ6HcANWxw/w-d-xo.html. My daughter has a 100 year old house in Wisconsin that I think would benefit from this technique. It is a dry basement but has efflorescence on the walls. I have wire brushed it off but it comes back. Thanks
I watched the video, and it looks like a great way to insulate and waterproof the basement wall. That said, if the drainpipe is compromised in any way, it won't do anything for you. As long as the basement drainpipe is working very well, this process would be a great addition to any home.
Drylock
@@FRENCHDRAINMAN Thanks.
I have only 1 wall in my house that water comes through. It’s a cinder block crawlspace. If I don’t do the whole house will I cause more issues than I had before? I will be doing a French drain out to the street as well as a separate pipe for gutters.

This is terrific content. What is so terribly frustrating is that it is very difficult to find a contractor who will take the time to execute the important details. So many outfits call themselves foundation waterproofing "experts," but really are just a couple of guys with a shovel and a bucket of tar.
I agree.
You're 100% right.
That’s a massive improvement to the property, great job.
what brand of liquid membrane did you use?
Poly Guard
Expensive
just a suggestion I did my own over 850 sq ft in a day with sand blasting with no help loading the commercial pot wt/medium sand & no damage to my block wall then used a leaf blower afterwards to remove all the leftover particles
👍
Would you recommend using the rubber membrane on the inside of my basement block walls? I will be doing a drainage system inside my basement with a sump pump soon. Do you sell the material and have the info for buying it? As always great videos!

Love your installation, but the running of the drain pipes from the sump pump looks terrible. Seems you could get it in the ground out towards the end.
We are in Michigan. When we bury in the frost, it freezes up.
So you did the foundation drain and back filled and the went back and did the gutters at a later date? I’m assuming you went that rt because of the rain?
Here's the playlist. Save it. I will add more videos in about a month.

What happens with all the holes drilled through the membrane to attached the dimple board?
Water's never going to be that high. The dimple border is for an air gap so there's no moisture.
Man what does something like that cost???
45k
With a home improvement that costly is the home even worth the money put into it. Would you ever get it back at a sell? Hvac tect here, alot of people like to jump on that geo therm for homes. But at 30k in the mid east. You will never save enough energy cost to cover the up front. I got $2000 in mine. 2 types of heat. A heat pump for cool morning and back up propane. Just a homeowner trying to save money. Beautiful job thou. I love a clean work looks great
I can't believe you guys are that fast. Amazing. I can't believe you done that must for the price you got. 👊 great team like you said in and out. Are you a licensed plumber. Or just a contractor. Hope you got thur the rain
What caulking/sealant is being used in this video? Thank you for everything. Im in Hawaii, walls are currently being built. I found a west coast distributor for Delta MS and having it air freighted today for $1K. Seems well worth doing it right the first time. The only drain hose I could source here can be crushed with a squeeze of the hand. I tried to find the 8 slot goods. Leaky CMU foundation is a very common problem with the hill side construction here. Someone could make a killing in Hawaii doing what you do with the products you use.

We used this product 1st. It might be overkill, but we like overkill. 💪
@@FRENCHDRAINMAN Wow, swift response, Thank you! I see you answered Poly Guard for the sealant coating to others as well. I meant the product in the caulk gun, applied at the top of Delta Membrane molding. Its a DAP Product, silicone? I couldnt get the Delta caulking from the source Iʻm buying the membrane. If its a PolyGuard product it does not show on the link you shared. Thanks again!
I’m surprised the foundation isn’t below the frost line. Is that common in your area?
When it is on a 42" footing like this one. Yes, this is common for home built on slab to have 42" footing under foundation wall.
Do you do the burrito wrap around the rocks that directly surround the foundation and dimple mat area? Or is that only needed for French drain lines outside of that area?
th-cam.com/video/luq8fnPk0M8/w-d-xo.htmlsi=BPh6PmZHSuvHQ-gD
I may have missed the explanation but clearly not every house requires a foundation drain like this? Is this required because of a combination of the clay soil, flat property, and just the amount of rain this area gets?
Also curious why you guys run electrical and sump discharge piping above grade and anchored to a wall/fence like that. I’m guessing there’s a good reason for it but at first glance it doesn’t look good. Especially with how clean the rest of the work is.
th-cam.com/video/i92tg09hm6Y/w-d-xo.htmlsi=fhpGYFg-CVBJDoUJ
@@FRENCHDRAINMAN Makes perfect sense. Thank you!
You have often stressed how important it is to move the dirt off of the jobsite when you're digging a French drain, and to replace all the dirt in the trench with gravel, so that the clay in the soil doesn't clog the drain. So why is it that you replace so much of the original soil on top of this foundation drain? Isn't a foundation drain essentially just a French drain that is buried? Why don't the same concerns about the clay clogging up the filter fabric and the gravel apply to foundation drains?

I had the same question and watched most of those videos. All great videos. All info appreciated. I'll watch more if I can in time. Contractors are here building walls, I'm doing the waterproofing and drainage solo. Thank you
Nice work. What something like this cost? I wish you were out of NJ
It's not cheap. The entire job was a week and 45k

Should have used the high pressure washer first before waterproofing you had time
It's was cool weather, and it would have made a muddy mess. We don't work like that. We think everything through. The men did a great job. Wouldn't change a thing.
@FRENCHDRAINMAN your foundation drain would have taken the water away though.
Job was 99% but could have been 100% with the pressure wash
Do you guys just call off for rain days or do you have rainy day work for the crew?
Always work the crew. They help in our shipping yard. They our Swiss army knives. Can do it all.
@FRENCHDRAINMAN I'm a contractor in Pennsylvania (decks, lawn drainage, fencing). This time of year, it can start to be a battle to get everyone enough hours, but its getting easier over the years. You guys are awesome, and we greatly appreciate the content!

@@FRENCHDRAINMAN thats not very helpful. supplies obviously arent where the expense comes from. then homeowners will need to factor in the cost to redo all of the landscaping which obviously isnt cheap. please dont spare the important details!

What's a budget for a project like this? Re: Delta board, builders here won't apply waterproof to the walls because they are so confident in the Delta board and its warranty. It's a big savings to the builder, but I wouldn't skip it. Nice work BTW
This was a 3-part video series. All the work was 65k
You don’t mind paying the cost when you know it’s an excellent and durable job. Too many construction workers flub jobs these days.
From your previous vids, I presumed you were 55-60. But here with the beard, beanie and glasses, I would think 40-45. Doesn’t matter regardless, just fascinating haha. You guys do great work.
