This series reminds me of old This Old House builds on the Atlantic coast. It would be interesting to see Matt+Crew do a reaction style video to some of much older builds with commentary about how building science has changed / advanced.
"Condensate" is a noun. "Condense" is a verb. Water condenses from the gaseous state to the liquid state. The water that has condensed is the condensate.
I was just thinking I hadn't seen a new episode of this series in a while, and when I finished the new Zip underlayment video, BAM! There it was! Great content Matt, I love seeing the videos that highlight builds in progress.
One of the seriously cool things to me is, after watching some of Matt's other videos, especially of his house build, and following Joseph Lstiburek, I can see where many of the decisions made here, would not be mine. Amazing how many builders/GCs, contractors are really not educated on their jobs. Not saying that is the case here. Great idea Matt.
When you run your plumbing pipe under slab I use 2" pics with electrical sweeps and pull pex through it like electrical wire From the fixture to the manifold then you have replaceable water lines I install both hot and cold lines in the same conduit it ok they won't fight
I would like to see what that fiberglass insulation looks like in 10 years. After a substantial amount of water has percolated through, it will carry small sand particles with it. I envision that full of sand in a few years.
@@onetwothree4148 probably because the spray foam on the inside will do the heavy lifting there. But I hope it’s not too expensive if it’s being used as a fancy pillow for any big boulders during backfill.
Can you demonstrate that the fiberglass board actually has the advertised drainage capabilities? I have a hard time believing that, and I suspect that the polymer-enhanced barrier would act as good food for mold.
Well, I guess it could make sense that a fiberglass material would stop and redirect moisture from the building which would eventually travel down to the crushed rock and french drain. But yeah, I don't disagree with you, it sounds like advertising BS that can never actually be proven. Not sure why the a polymer asphalt would attract mold though? I mean, anything basically can get moldy, but not sure its any worse than any concrete barrier product on the market.
That stuff definitely won't sustain an R-10 after back-fill, but the closed cell spray foam will provide plenty of insulation for an underground wall so it doesn't really matter in this case.
@@zack9912000 CLOSED cell spray foam does not absorb water. It is entirely impervious to water. That is why builders like to use it (instead of open cell) in applications like this.
@@zack9912000 I'm trying to understand why you say this is a bad idea. I lived in Rhode Island and saw this technique on a number houses being built, seemed to be more or less standard practice. This is the first time I have seen spray foam used instead of sheets of high-density foam but the principle is the same.
The floating basement slab has me scratching my head. You'll have a 2" foam conduit the entire perimeter of your basement. That /can't/ be good for pests, water, anything other than insulation value.
And you forgot RADON ! Tho don’t there is any radon on that sandy island…..thomplnety back in mainland Rhodey, right wade 😂,I agree - I’m skeptical of the thermal fetish that seems to emanate from New England where bugs all die out in winter and they have minimal termite pressure.
Thanks so much for this informative video. I don't have a lot of $$ but i have land an am trying to build a small high-performance home with a walkout basement.
Multiple questions: Why not waterproof all the way down and all the way up? I've heard some say filter fabric gets clogged over time and actually makes things worse. Is that true or just a myth? Wondering what the optimum is for drainage installation for the long term and if my past specs for filter fabric were wrong.
Nice details! I wonder: have you ever heard of Mike Oehler's " $50 & up underground house book"? I know, the title says it all, but it's really quite interesting. I'd love to get your take on his simplistic version of earth sheltered housing. Costs, benefits, waterproofing details, ventilation, etc. This video on basement building just got me thinking about it.
Matt, I’ve got to ask. Was that your wife on the pre-roll for ‘The World and Everything in It’ podcast yesterday? (If not, I highly recommend the podcast!) Love your show, keep up the good work, Brother.
Do you guys ever use something like the Form-A-Drain system? It seems made to order for both a coastal situation like this one _AND_ a caliche one like in most of central Texas. Both for taking care of ground water infiltration and Radon issues.
Matt, have you ever heard of ALCHIMICA Building Chemicals, polyurethane waterproofing membranes. Could you do a video reviewing the quality of different water proofing liquids?
I have a hard time understanding why to use mechanical fixing (that probably is perforating the waterproofing layer) of the insulation board. Did I not understand something right, or this is normal procedure?
Between the exterior waterproofing and the interior waterproofing that foundation wall is going to be compromised after awhile. Also the fiberglass on the exterior is crazy.
I'm surpirsed folks like himself are using this. If they accept using fiberglass for drainage and insulation, makes me think twice about the ZIP system, which is OSB, with some paint.
My thoughts exactly. A dry sponge is a pretty decent insulator, as trapped air is the insulation medium. But a wet sponge is absolute crap at insulation. A product like extruded polystyrene (EPS) will lose hardly any R value over the years. Of course the wall will need dimple board over the outside of the EPS for drainage.
Especially in applied right and it “skins” …actually subslab is one of few areas I’d feel comfortable using closed SF as I wouldn’t worry about long term off gassing…not sure I’d bring it up the foundation wall. It will eventually retract at that cold joint and now you have a leak for subslab radon . Of cousre if u r gogin to spray foam entire foudnation wall makes sense, but otherwise I’d use aeroaggergate /gravel with taped stego warp/stego homeand run that stego up about a foot on foundation wall. I achieve a breaker bond with minimal leakage, teh. Can run something like halo up the interior foundation wall. It is cool however not to have to tape foam boards and seal pipes with mastic subslab, no doubt !
Waste waste much waste of time and data watching this video...There aremillions to watch just any guy talking ..just put the tv ON , there you go, whatevr comes will be much more interesting to watch than this..

Hey Matt.... Did you ever do a follow up on that ram earth project? Is there any information on it so we can see it finished?
I used to live on Block Island and miss it..
Loving this series
Great job Wade, thanks Matt.
Dang, I was hoping it was a tropical island, I've been watching all of your videos to prep for a build in the Caribbean.

After 20 years it looks like the day it was installed. I have seen it dug up for additions.

that board is compressible - i can see how it might drain, but how do you sustain an R10 ??

Cool series, keep up the good work. 👍🏼
Awesome series guys.
I like the idea of 2" closed cell foam in the basement floor and walls
The fiberglass will compress negating insulation value. Could end up holding water and drawing heat out of building?

ICF stem wall with monopour footing is so much easier/quicker with probably better results, but perhaps they cant get a pump truck to this location?

What did they use to fill the holes from the form ties?
Great story

Excellent
Closed-cell foam: so please tell us a little about how you will force ventilation throughout the basement.
It's an unvented design. Like the rest of the house.
Wet boards have no insulation effect

@@johnwhite2576 Thanks, I knew there had to be other options
Matt, have you ever heard of ALCHIMICA Building Chemicals, polyurethane waterproofing membranes. Could you do a video reviewing the quality of different water proofing liquids?
Have you ever overlapped tremco onto wood sheathing, similar to a liquid flash?
If you do such a good job of insulating the foundation don't you lose the temperature moderating benefit of being partly earth sheltered?
Interesting question!!!
wade-why aren't you using tremco tuff n dri spray on ??
I have a hard time understanding why to use mechanical fixing (that probably is perforating the waterproofing layer) of the insulation board. Did I not understand something right, or this is normal procedure?
What is the pro vs con of doing a build like this vs ICF?
Where is the french trench for draining?
Between the exterior waterproofing and the interior waterproofing that foundation wall is going to be compromised after awhile. Also the fiberglass on the exterior is crazy.
Hey you planning on doing anything special when you cross the 1 Mill subscribers milestone?
That board looks like a great sponge, not convinced it will assist with drainage.

Wouldn’t it have been easier to raise the house on footings?

The insulation should stay very dry in order for it to be effective, wet insulation is ten times worse than no insulation.
Guess you didn't listen and you did no research
@@daveklein2826
Try to keep your feet warm by soaking your shoes in water and let me know.
that spray foam insulation layer along the whole pre-basement surface is smart!...a water/air/heat-tight blanket, basically.
Not really, if any moisture hits that foam, it will suck it up like a sponge, and you lose any ability to insulate. It will also compromise the slab.
@@zack9912000 Pretty sure that closed cell foam doesn't act like a sponge the way open cell does. It should seal.
@@zack9912000 closed cell foam is absolutely, completely waterproof.

I think the pink board will act like a sponge and I would have made them spray the outside too!
I don't think they care about the insulation. Probably a cheap way to protect the waterproof barrier
The fiberglass drain board drains quickly to maintain its insulation properties. It works.
Closed cell on the outside would be a disaster.
@@roberthawk5390 closed cell foams are a far more common spec on the exterior of foundation walls. A waterproofing membrane goes on the wall
@@onetwothree4148 Having knowledge of almost 100000 homes with Tuffndri installed on the foundation walls you are incorrect.
I’m going to go ahead and disagree with a fiberglass exterior insulation. That stuff sucks in moisture inside. I’d prefer a foam outside
Kinda disappointing to wait 3 weeks for 8.5mins worth of build 🙃
Poor baby
I think the word you’re looking for is condescending not “condensating”
Yea I don't agree with spray foam right on the ground. If water reaches that foam, the slab is compromised and will require a complete removal to fix
