DON'T Miss This Critical Waterproofing Detail

[@hotdawg9840]

If you guys are looking for good building content and want your house done right. Watch all this guy's videos. Matt Risinger is the man.

[@markpalmer5311]

I want to lead a campaign for Texas basements! We should be doing this, especially in all the infill construction going up on small lots in the old, close-in burbs. Great space for mechanicals and storage, shops, etc. And Polywall is in Ennis!? Spectacular.

[@adrielrowley]

And a basement can sit on more solid soil, not clay that gets water logged and causes homes built on pier and beam to go way out of whack, constantly needing leveling. Or post tensioned slabs. My understanding is below four feet the ground doesn't move and why pole barns stay strong and plumb. Or am I wrong?

[@terryf3434]

I used a system like this 23 years ago when I build my basement with ICF. I used 3/4inch washed gravel fill around my dimpled system. I used engineered panels above grade because at the time it was 20% cheaper than the ICF. My brother built his house all ICF all the way up. I would never built a house again without using ICF construction. Trust me here in Ohio we get temps from -10 to close to 100 degrees and I can honestly say that I don't regret using this type of construcion. Yes it costs a little more but between having all this foam in house and using Geothermal heating and cooling it doesn't take long for the return on investment. Unfortunately a couple of years ago we had a fire and the foam will not burn! It does shrivel up from the heat though. Was easy enough to replace the SIP panels that were damaged.

[@TimMaxwell-j7n]

Thank you for using our STA'-PUT Quick Grip adhesive, Matt!

[@BrianBriCurInTheOC]

DRAINAGE EXCELLENCE!!! Thanks MATT R!

[@MRosati5000]

Protecting from the outside is the way for foundations. it seems like quality ideas on Matt's show. I like.

[@TheGregWallace]

Seems like that dimple mat should have the nipples toward the concrete to hold the dimple mat off the concrete. Because the filter fabric will end up being pushed into the dimples or get full of dirt . With the dimple against the concrete the channel for water to flow down will always be open.

[@Luckingsworth]

I think you are exactly right. Common problem of a general contractor not knowing how to properly install a specialized system. But then again most foundation waterproofing/repair companies are equally inept and at least they are trying here. I will give them that.

[@p4ddy100]

I was just thinking the same thing, and was scaring the comments to see of anyone had an opinion on it. Thanks 👍

[@christopherbeddoe406]

I've seen products that are intended to be installed dimples in. They come without any fabric layer for obvious reasons. This product is designed to be installed as shown dimples out. Like you said though I'm skeptical that a little fabric is going to do anything to help keep that soil out when back filled especially over time.

[@JMoney-ne3to]

I too was looking for like minded people. I do not like the way they do/did this. The water won't be able percolate down to the drain tile along the 'poly wall' side. The flat side is glued to the 'poly wall'- leaving sealed little dimples in big wide areas of adhesive. Wouldn't be any different if you glued a 1×12 to the polywall around all the edges. Nothing will move easily through the areas they placed adhesive. It may even TRAP water between the polywall and the dimple mat, depending on if they go along all the edges. The dimples facing outward will be surrounded by stone and dirt once the felt fails to hold it back, so again, nothing will allow water to percolate easily down to the drain where you want it to go. Not to pick on this channel (cause I generally like it) but I can see the next step would be: "...now put a waterproof hard wall backer vinyl plywood, with antimicrobial semi sealing lattice vanes over the felt /dimple side, and voila! You are done!" The waterproof wall that costs a cool $1 million to do. This is NOT well thought-out. Pretty expensive too, considering it won't be doing ANYTHING in a few years.

[@practiceguild1116]

This channel is a master class! Thanks Matt!!!

[@matthewcrockett106]

Well thought out as usual. Also answered a concern I had of keeping the poly wall from being scared in the backfill and compaction process. Love it!

Thank you Matt. 20 years ago dimple matt was a pain to put on being able just spray and apply so much better. This series was very help for sealing up poured walls of all types.

[@genecarden780]

What the hell are you talking about? Dimple mat has been routinely used for more than 40 years.Anyone with any knowledge of waterproofing takes dimple mat for granted. Anyone that thinks it is hard to install has zero knowledge of waterproofing. In the industry it is called drain mat

[@louismorejohn586]

Arroyo = stream. Zanja = ditch. Good video.

[@nrosario]

I know this video was released 4 years ago, I have been researching this method of waterproofing ICF, one thing I couldn't find is the Pink Primer that you used to coat the ICF before applying the Poly Wall.

[@mastersparkee59]

They sell it on their website

[@andrewk-majordochomerepair6014]

Matt, two questions ?? 1. Would you still apply this over an insulated poured cement, in-ground foundation? 2. If you insulate the foundation, which essentially acts as a water barrier itself, would you still also apply a stick-on or roll-on waterproofing membrane underneath the insulation panels?

[@boedillard8807]

If this was in a cooler climate, would what insulation would you use and where would you put it?

[@Prorex1911]

It looks like on the joint, only the filter fabric overlaps like a shingle and the backing butts up together with no overlap. Maybe I’m seeing it wrong. If not, I think they should put a flat lip on the upper back side for the upper section to lay over, preventing water to enter at the seam. Probably overkill, but if you’re going that far...🤷🏽‍♂️ why not? Great videos!

[@MerkDolf]

Looked to me that the top of the base wall is missing about 2" of dimple 6:05, so I would assume it is meant to overlap that as well.

[@NevrrPresntt]

We call it drain board or protection board. I love this type of work. Below grade wp. I also really enjoy working with traffic coatings, I'd maknly do those in parking structures. Edit: we also use the 3M glue that comes in a cylinder as well. Really gets the job done.

[@msdarwin04]

Matt Risinger, Great video as always. I find myself coming back to a lot of videos because of the detail. I have wondered about something and have not seen your take on it. Below grade SIPS. There are a couple of companies that are doing this and wanted to get your take on the viability based on what they are doing and how it would be best to seal it from the soil much like being done to concrete or ICF.

[@RiotGearEpsilon]

I've been a huge fan of Matt's videos recently, but what I'm even more interested in is similar content with a focus on high-density housing, such as apartment blocks, condominiums, or public housing projects. Can anyone recommend a good channel for that topic?

[@FlyingSugarCat]

No bugs live in mine. My top is completely open no sealing strip. Dimplex on bare concrete with minimal fasteners along the top. Basement is cool in summer and warm in winter. I believe the concrete foundation walls drying out has created more of a thermal break due to the porous nature of concrete.

[@rafaelreyes4907]

Will you go over properly waterproofing window and door openings and proper window door install for this ICF project? There is no good info out there for waterproofing openings on ICF.

[@duntone]

Matt, have you seen, used or have an opinion about Form -A- Drain or Fast Foot Fabric footers? They both claim to be far superior to traditional footings for waterproofing but I can’t find an unbiased review.

[@jamesschneider6136]

Doing the exact same system on a custom in Lago Vista, TX! Thanks Matt!

[@victorvek5227]

Matt I have a basement with a perimeter drain... would this work as a continuous drainage mat / air seal down the interior walls of the basement to the perimeter drain itself? The perimeter drain will be hooked up to two sumps with airtight lids.

[@sef2273]

How does this mitigate heavy saturated soils from pushing on the foundation wall?

[@christopherbeddoe406]

[@derektang6450]

Does the water come out at base if the dimple board?

[@phillipkuntze137]

What's the difference between using this and the traditional spray tar

[@WearySteerer]

My tech teacher told me he puts a coping at the bottom of his foundation wall. I think a trough or gutter system would also work well under that to displace the water

[@trollstalker528]

How much rain / snowfall do I need to worry about if I'm going to invest in what is an extra step where I am located. Where I am we receive only 6 in of water per year. If we got a hundred inches of water per year I could see the need for the Arroyo and the poylwall. How many inches of water do I need to worry about before doing this extra effort?

[@dcentral]

How long will spray adhesive last keeping all of this up?

[@nottherealjk]

Once backfilled it'll be pressed against the foundation and you don't need to worry about the adhesive.

[@YannickRoy76]

Awesome system and all but They make this in Texas but do they sell it in Montreal 🇨🇦?

[@frankbiz]

What a great system, I would definitely consider that if I were to build. A year ago I just bought a duplex condo, we are high with great drainage, no water issues at all. I would like to finish the basement, I run a dehumidifier all spring and summer to keep the humidity at 45%. Concrete is porous and before I stud it, what would be the best treatment for the walls and floor? I live in southern Massachusetts. Thanks!

[@allach1772]

Is there cheaper way to apply adhesive other than spray gun? The adhesive with spray gun costs a whopping $1000.00

[@MurphysLawUs]

I’m looking to do some renovation on a 1923. My personal home. It needs leveled. Should I level and then poly/dimple. Or should I just replace the whole foundation wall and start from scratch?

[@360milliondollars]

Would this need to be done to a retaining wall if I were to make that an open area under ground courtyard, instead of having the back fill come up to the home, the back fill goes up to the retaining wall or is that a different process?

[@peterbergeris6510]

Matt, I have dmx above the basement floor level and a few inches up against the cement wall from below. I want to insulate and rock. Can I put a baseboard over the dmx? Should I use pcv or MDF ? I have a vinyl floor with cavities underneath to direct condensation.

@@daveklein2826 The majority of the system is below grade you are correct. Are you suggesting that you would stop it some inches below grade and the ground covers the transition? I would assume that the dimple mat will come up 4-6" above grade thus a portion would stick out above that could be damaged by weed eaters and lawnmower not to mention looking unsightly.

Ant colonies, yellow jacket nests, termite nets, any other bug that lives in a colony underground. I would assume they would rather move into an existing underground space rather than digging a fresh space.

[@williamanderson7215]

So many steps to finish this ICF wall foundation, I wonder if they can simplify it to try reduce the cost.

[@christopherbeddoe406]

Lots of these are "Extra" steps to really make a premium final product. The dimple roll stuff isn't excessively expensive. I've seen so many basements that leak that I'd spend the little bit extra to really go overkill like this and make sure there are no issues ever in the future. ICF really doesn't require any waterproofing you wouldn't do on a block or traditional form poured foundation.

[@FlyingSugarCat]

I used Delta Drain on my 1970 bungalow all the way around. I I think the Peel and stick with a dimple membrane is a tad excessive.

[@caustinolino3687]

1:30 Why dont you want to fill with big rocks? If the point is to maintain dimples, tiny rocks willl fill the space and defeat the purpose of dimples. Only rocks bigger than dimple spaces will keep the spaces open.

You can use standard cement, but certain hydraulic cement may get a bit too warm or exert pressure the foam blocks may not be able to handle, you can use any cement mix of at least 3,000 psi and up.

The problem is that most builders don't want to pay for this. They barely want to pay for the spray or roll on membrane. I have been waterproofing for 20 years and 95% of my jobs we just spray the walls and they backfill against it. That being said, just the spray is usually good enough I've never had a foundation fail or leak and I've done 5000+ in Massachusetts.

[@percival23]

So the water proofing can't get wet a lot so the waterproofing needs it's own waterproofing. Got it.

[@nightc1]

I don't think it's that the waterproofing can't get wet, it's more about controlling the water on the property. Additionally the air gap should help the underground part of the house be more conditioned. Controlling the water is the same reason we put in drainage ditches and gutters and stuff. It's not a bad thing.

[@nelumbonucifera7537]

Drainage board isn't waterproof. It just protects the water resistive membrane from mechanical damage, soil microorganisms, and high pressure. By your reasoning, siding is redundant, we should only use house wrap.

Why don't you just clean off the concrete, spray foam the entire exterior of the basement from the lower plate down and over top of the footing...and DONE...one piece, no leaks, and insulates from heat and cold. This is what I did around my old basement (1950's) and it is by far the warmest room in my house in winter ( I live in Snow Lake , Manitoba, Canada, where we have 6 months of winter and minus 35 degree Fahrenheit temperatures for weeks on end). I should also mention that because my lot slopes two ways, part of my basement is above grade...and it's still incredibly warm. You should try it sometime, it would probably be more cost effective and quicker with a better result. Cheers from Canada!

I agree. A thick plastic membfane over the water proofing to prevent is from damage and a stone backfill from footer to daylight will do the same but on a far more massive scale.
