We had a thick layer of tar sprayed on the walls and footing, then an 8 mill plastic sheeting stuck to that, then 2'' of Styrofoam. 2 - schedule 40 pipes with the holes pointing down on rock around the footing and back filled with trap rock. A layer of landscape fabric was placed between the dirt and stone for separation. The stone was installed all the way to within 16'' of the top. Not even a hint of moisture. That's how you keep a basement dry.

The only problem is when the tar dries it will allow the plastic sheeting to pull away and moisture to get in. The good news is it takes about 50years for that tar to dry out.

Let me ask - see how the footing is square to the foundation wall? Ie the footing is wider than the wall, so at the bottom of thew all the footing sticks out at a right angle. But can't water collect there? Why not have a "tapered joint", ie build up some concrete there to push the water away? I know its dirt there after it gets back filled but its gets saturated then the water can settle to there. The things is is that backfill is less compact than the regular ground so water will move from the more compact soil to the backfill every rain.

Overall good approach. For my jobs, I prefer to ratchet it up a notch or two, however. Background is that for the past 30+ years I have done all new work with continuous exterior foam for basements and crawls, in Massachusetts, New Hampshire and now Colorado. I have evolved continually over that time span, and best practice now is: 1) Rub-R-Wall hot liquid spray applied waterproofing. Needs no special prep on the concrete. Goes on about 1/8" to 1/4" thick, and bonds ferociously. Cover from outer edge of footing to about 4" below TOW. We use primered, self-adhered membrane (from supplier of the liquid applied on the sheathing) to cover the jump to wood. The sheet material is more resilient at the concrete to wood interface, far less likely to be torn or violated. 2) The Rub-R-Wall guy installs Dupont 2 1/8" Perimate foam over the cooling rubber coating as he goes. Foam more or less sticks, and is also fastened with a few powder actuated pins going through special plastic washer caps. Perimate has keyed drainage slots vertically along the 8' dimension, which have been tested and proven to not silt up over time, thus serving the purpose of the drainage mat. The Perimate is met at the top by the continuous exterior wall foam, faces are flush, so no cold band (heat loss). We typically hang factory finish (colored) Galvalume steel from up under the siding, to about 6" below finish grade. Protects the foam (UV is the big disintegrator of foam), looks good, is an easy fit-up. Our climate, the Perimate controls dew point/ condensation very effectively in our jobs. Typically will have stud walls with R-13 FG batts interior, with no issues ever. 3) Filter fabric from footing to far side of excavation, and upwards from there, with 4" perf drain laid in, holes down. Gravity drainage, even if it means a lot of digging to daylight (no issues with power loss/ pumping in storms). Sump and pumps only if absolutely no gravity path available. 4) Fill trench with 3/4" crushed concrete to about two feet below finish grade. Crushed recycled concrete has been cheaper than stone. Install 4" solid drain pipe, with standpipes for all downspout locations, pitched to dedicated gravity drainage outlet as per perf pipes below. If the roof water isn't down in the trench, why put it there yourself?? Now fill the trench to within 6-12 inches of finish grade, filter fabric over, and soil to taste. I don't mean for the help to take a dump on it, by the way. 5) We are in radon territory. Interior gets full drainage system, pitched for water, covered in crushed concrete. One or more radon vents go up, from the same perf pipe setup. Dedicated gravity drainage as per other systems. If gravity not possible, use a sump and pumps to lift and dump into the RWL solid pipe above and outside. And seal the sump, for the radon. Only downside to this is that my Rub-R-Wall guy died of a sudden heart attack with about a day's work left on my last project. His son-in-law finished the job, then dissolved the company. It is a franchise, and I don't know if anyone ever picked up the Colorado territory afterwards. A big loss for the industry here, this is the ultimate foundation waterproofing system. I haven't actually done any foundation work since.

Two things drive a builder to use these kinds of products on building, the owner requesting them used or the risk of ignoring the water issues. And this risk is minimal because of it becoming the homeowner's problem a year later when the warranty is up. So I love the idea of adding proper waterproofing products during construction but for 99% of us plebs, we will get what the track home builders give us, and that is the cheapest possible solution that will work just long enough for them to not be financially responsible, and maximize the profits for that builder.

@@JamesBlazen Exterior pretty much the same as a conditioned basement, as I described in the long original comment I posted earlier for this vid. Probably the only significant difference will be the interior. Radon is a big deal here, and virtually all new structures must have radon mitigation built in, even if the power venting is not needed at the time. Cold and frost line makes crawls a minimum foundation standard (likely to be drilled caissons with grade beams, the normal nomenclature in these parts), as an awful lot of the soils are far too hot to float a slab on grade; that kind of stuff is just not done around here. Okay, back to topic. The interior will get graded out to bottom of footings or the grade beams, and then 4" perf pipe in crushed stone or crushed concrete (stone size dependent on issues of handling, but normally 3/4"). Drains run out, and radon venting goes up. For a crawl, we simply use 10 mil clear poly over the stone, in the largest pieces/ fewest joints one can. There is a good trick with the expansion joint material that I like. Rip 1/2" off the edges of all pieces, then pin the rips back on to the larger piece with small finish nails. Snap grade lines on the walls, pull the poly up at the foundation walls, and use masonry nails or powder actuated to fasten the main width of expansion joint to the wall. Then 2" +/- of 3/8" aggregate 2500 psi fiber reinforced concrete. Pump it in real wet, screed neatly to the top of the expansion joint material, and bull float to suit, walk away. The concrete is to maintain the integrity of the poly, and hence air/ vapor seal: it also makes a clean work environment for the trades, and any future activities(like personal storage). I do not normally use any foam insulation under the crawl slabs, as we typically have radiant floors with insulation below, in the joists. Temps in the crawl are intermediate, and don't vary widely.The soil mass below will basically stabilize out to something like 55 F, more or less year-round. The exterior foam keeps humidity and condensation from becoming an issue, as the foundation walls could be otherwise affected by changing outdoor ambient temps. The last task is to give the concrete topping a week or so to cure, and go then go back and pull those 1/2" rips off the top of all the expansion joint material at the walls. Leaves a real neat groove, with pre-installed bond breaker at the bottom. Just right for a pourable two-part polyurethane sealant, or a gun grade, if you prefer (trim poly to the groove). Another note about radon: if a sump system is required for the interior, then the sump itself must be sealable (lid) at the concrete surface in the crawl, to prevent radon entering the space, or reducing the effectiveness (pressure drop developed) of the powered vent fan above.
@leestevens4464 жыл бұрын
@@JamesBlazen 1) it has become the industry standard/ trade practice hereabouts 2) neither The geology basically dictates, or at least heavily influences. There is a huge range of soils and foundation conditions along the Front Range of Colorado. Once down off the Foothills and onto the " flat" Plains, one is on the ancient seafloor. It is layers of sedimentary rock (mostly shale and some sandstones), layers of oil and gas deposits, and more sediments on top: all hundreds or thousands of feet thick. The lower layers have been so compressed that the original sediments have been turned into those shales and sandstones. The topmost layer has been compressed into a hard layer, that can appear to be stone, but isn't really. We call it claystone. It is composed of expansive clays. Water penetrates down very slowly, and causes the claystone to revert to clay as it gets wetted. Typically, the top 5 to 15 feet will be softened and unstable. Anything founded in that top layer will move, heave, possibly for years after construction. The nasty part is that if one digs for a foundation, the water penetration is pushed downward as a result, just keeps getting softer, deeper. Best practice (usually mandatory per code) is a soils test and report from the geotechnical engineer. The report will specify design parameters for the site, and in these cases, that is caissons. The structural engineer will design the foundation per building loads and soils report. Typical house will be 12" diameter caissons, 10 to 15 feet into the undisturbed claystone, so maybe 15 to 25 feet total depth, but not unheard of to go 40 feet deep. The bearing capacity is a result of the footprint, and also the friction/ interlocking of the vertical sides of the caisson into the solid claystone. It is necessary to also look at and consider potential uplift from the softened material in the topmost layer acting on the upper part of the caissons, during engineering. A modest two story may need these every 10 feet of foundation wall, give or take. The soils engineer must be on site for the entire drill and fill, and approve each hole as it is drilled. A concrete pump is standard, with trucks rolling in as required; the holes must be filled immediately as they are bored and approved ( to avoid water intrusion/ softening/ collapse). Typically 2 to 4 re-rods will be inserted full height in each, sometimes full cages are specified, most likely for larger diameter bores. Here, the caisson industry is like the post-tensioned industry in Matt's Austin. The most prevalent technology will likely be the most economical, and no sense wasting energy fighting it. Now after all that, we also see incredible gravel deposits, along the current river channels. Might be 1/2 mile wide, probably good conventional bearing. Get near and into the Foothills, and anything may be found. Could be solid granite (pin to it), decomposed granite (claw it out, conventional footings), gravels, clays, mixed up combinations (really need the soils engineer for them), and sometimes even decent ordinary soil. We have had jobs where the best solution was 24" to 48" diameter caissons (needs the footprint for the loads and underlying soils) that were drilled through 5 to 8 feet +/- of mixed junk, to hit good bearing (like solid gravel deposits). We have had jobs in marginal soils (slightly expansive, not over claystone), where we were able to use interrupted footings. This mean an array of concrete pads, providing bearing for the grade beams (could be a full basement height, or a crawl) on void between the pads. The pads are sized per the building load right to the limit of the tested bearing capacity of the soils, so there is not enough surface area for the slight expansion to generate measurable uplift. Bottom line, it pays to have a good pair of engineers and a big arsenal of possible techniques to handle whatever you have to deal with. TMI ??

we did much the same thing on basement that was entirely below grade. it was connected to walk-out garage that previously had major weeping issues which is why I researched all the options. I think it was peel and stick, drain panel, then gravel and filter fabric. homemade drains out of thicker pvc pipe with holes drilled ourselves all inside a filter sock. Landscape pipe looked like it would crush. I put a lot of drains to daylight under the slab and put the whole thing on 1ft+ of gravel. AND a sump pump in a deep corner too. a big difference is that I spent an extra 25% on the concrete to get Xypex waterproof concrete. crystals that swell up with water and seal all the holes. We knew it was good when it rained all winter before we framed and the basement filled with water that would not drain, even through the cold joint. waterproof concrete works well. I could probably have done without everything else, but like he said, it's a belt and suspenders type of thing. All the preexisting weeping problems disappeared from the rest of garage and foundation under house nearby too. I think previously, the clayey soil had resulted in the foundation sitting permanently in water retained soil, and doing the basement like that lowered the entire water table around house.

If you completely wrap the footer pipe in the filter fabric, unless you are in very sandy soil like Florida (and IMO you should use Easyflow), the filter fabric will retard the water from entering the footer pipe and with clay type soils over a short time will seal off the footer pipe because the filter fabric will become clogged with fine silt. The proper way is gravel, footer pipe with holes pointed down, a layer of filter fabric loosely covering the top of the footer pipe, and gravel to grade. Do not encase the perforated pipe in fabric.

Homes need to sit higher than the surrounding land. Even a one foot difference slope makes a huge difference.

Absolutely. Most water problems are due to poor site preparation. You should notice a slight grade rise 15 feet away from the foundation. You should plan for drainage during the build and not depend upon sealants to keep water out. I know of a house where the water pressure under the basement slab broke a hole in the concrete floor making a loud pop when the water began pouring in from below. Poor drainage will also cause a slab foundation to crack.

Why wouldn't you want to extend the basement waterproofing to the sill plate and extend something like the prosoco fast flash down top of the polywall. Aren't we always trying to ensure continuity of the control layers? I have no experience with this, just curious.
@Retanaru4 жыл бұрын
Above ground gets plenty of air to dry out with. The issue underground is that the water sitting next to the foundation has time to seep through over days and weeks. Then you get into UV rays and other environmental issues above ground (careless weed trimmer usage) that make or break the budget when it comes to using a single material layer all the way to the sill plate.

I have to say you are so right fella. Shame your contractor buddies will always cheap out the job. Also. having holes on the bottom will always be the ticket. When you drill holes on the top and do not deburr the holes you are actually insuring the bur will cut the membrane fabric over time and cause clogging. Using your fingers to remove the swarf bur cuttings created is most certainly not the ticket. But your multi method I would say is spot on. Great video too fella. VF

@tullgutten Жыл бұрын
Always best to keep the water out instead of blocking it in. But there is a large investment to do the outside but really worth it. You gain insulation value in the wall from drying it and you prolong it's life from rusting rebar away, cracking, frost damadge, mineral depositing that causes the concrete over the years to weaken and crumble. And the innside then gets easy to insulate further and without rotting and water damadge. Some have innside "french drain" where the floor circumference is hacked away and drilled holes to the outside to drain the outside. And you still need to water and damp proof the wall innside 100% before doing anything since the wall will still be wet

@@JeepWranglerIslander good to hear the sump runs a lot so your drain tile is doing it's job but on the bad side you've got an issue with runoff going in the wrong direction, towards the house. When I built in Michigan the soil varied from pea gravel (Lake Huron shoreline on Mackinac Island) to solid clay so there was always a challenge. If you're at the low end of a long slope in the terrain, it may be more difficult to come up with a satisfactory way to channel the water from the exterior wall. Start with what you can control, gutters to move the concentrated runoff away from the house. Digging out the backfill down to the footer would be a worst case scenario, not to mention costly.

Agreed. I ask because I live in a 1935 house and redoing the outside of the foundation is not an option. I’ve researched other products for sealing concrete on the inside. But the poly wall sealer seams to be a much better product then I’ve been able to find on the internet. I don’t get water in my basement but it does have that damp smell to it all the time.
@leestevens4464 жыл бұрын
@@christopherattfield5507 I would expect the damp smell is attributed to moisture migration through the concrete, and or condensation on the colder wall surface from humid air in the basement. Might try a dehumidifier. This is why I do only continuous exterior insulation on basements and crawls (new work) for the past 30 years. Completely stops the condensation/ humidity problems, totally changes the basement environment. Problem with coatings on the inside is that moisture migration through and vapor pressure developed on the inside surface of the concrete wall creates a substantial force to separate the coating from the wall. You can try, but it is based more on hope than certainty.
@internettoughguy4 жыл бұрын
@@leestevens446 As you said, vapor pressure and moisture migrating through the concrete towards the inside will eventually cause any coating to peel off. It's just a matter of time. There's no getting around this. Waterproofing concrete from the outside is the ONLY way to do it. Physics says so...no matter what Joe Blow the sales guy tries to tell/sell you.
@leestevens4464 жыл бұрын
@@JamesBlazen Four feet. Ha, simple answer. Except I hate simple answers. For a basic job on easy, flat ground, the idea is to almost max out the concrete forms used, and 4' forms are most typically used. We have 36" frost depth, and have to keep wood (even treated sills) above finish grade by some increment, so this works on footings or on caissons (the form void will use up the specified height inside the bottom of the forms, say 4'' to 8", but frost heave is not so critical sitting on the caissons). Some cheapo's will use 2' 8" forms with grade beams, but this gets tight in the crawl, I would not do that. The cost is doing the job, the height reduction does not save an equivalent % of cost. With nominal 4', there is room for ducts and drain pipes, and a tradesman can still get around to work reasonably well. We put in permanent lighting and a power plug, even if no equipment in the crawl (then it is code requirement). Now, the variations: because of expansive soils, any job on caissons with a basement has to have a structural floor. This is now mostly an engineered reinforced concrete slab over foam insulation, poured over form void. Then builder's choice as to whether it will be in-floor radiant, in the slab. It is also possible to do a structural wood framed basement floor, hung from the foundation walls (usually with caissons, steel posts and carrying beam) over a crawl space below. Did this only once, when first arrived in Colorado, but probably never again. Foundation wall pour gets really high, and costly. The crawl gets cut to minimum depth, like 18", and then it is a nightmare to work in: there is always at least some plumbing, and a sump system. This becomes an orphan space, out of sight/ out of mind. Not all that great a scenario, but it does not ever heave, which is critical. And, yet more. Pretty much all jurisdictions here are limiting % of lot that is covered, limiting height (in several aspects) and limiting floor area built. In our culture (especially here) everyone wants max size, so basements are in. Interesting thing about the building codes, any space with highest ceiling height LESS THAN 6' 8" is not "habitable space", and not counted as floor area. The last large project was 10.5k sq ft, on the permit. In fact, there was about 1k sq ft of floor area inside the altered/ added to foundation, that was purposefully built at 6' 7" from top of full floor slab to finished ceiling. Most was used for the mechanicals and other equipment. Legally a crawl space, but full exterior insulation and very nicely finished off. The point? All jobs are designed with a large array of factors clearly in mind. Not just owner needs and desires, but also soils, frost, water, surrounding terrain, mechanical systems, structural considerations, insulation strategies, planning regulations, building codes, and so forth. FWIW: my original stand-alone comment on our basement strategies got sort of mangled in posting the "Reply". Just noticed it, and think I got it edited and corrected. It came out somewhat unintelligible on the first go-round.

Other than a (relatively) minor cost aspect, now that the Polywall roll on is a nice neutral gray, why WOULDN'T you coat all of the concrete?
