I'm a Builder that has always included an interior perimeter drain and most projects have spray foam insulation, (trying to get away from that!). As the spray foam insulation is typically applied directly to the concrete foundation wall it effectively seals the interior drain ☹. I have been a proponent of adding a dimple mat to the interior foundation wall to allow moisture a path to the interior drain. This is the 1st video I've seen with the same concept, Bravo!!
on the house i just finished, i did an ICF foundation with a waterproofing product and dimple mat. i think the waterproofing product i used was tremproof 260, roller grade. i wanted to use tremproof 250gc because it has a much lower vapor permanence but it isnt compatible with ICF whereas 260 (or whatever it was) is. would it not be a good idea to have the lowest perm rating possible on the exterior waterproofing? is there something like 250gc for ICF? seems like it would be good not only for moisture but also soil gases. i also want to ask you about this: like i said this house was new construction. but after drying in i noticed that the basement had a certain smell to it. not a musty smell but something different, but not artificial or solvent-like. do new basements sometimes have a smell because of soil gases? the smell persists even when a radon fan is hooked up to the drain tile.
I thought about doing a light layer of spray foam and pressing 1/2 rigid foam against it while it’s fresh to essentially make a 100% moisture seal, is this smart or foolishness? 😂

Im a simple man. I see new asiri videos, i click. Thank you for your work.
I appreciate your support!
Wow. Your basement videos have answered all my questions. Thanks!
The knowledge you give in your videos is really high quality. I say this as a municipal inspector.

2:30 best summary ever
What do you like using as a capillary break between wooden walls and concrete slabs? Or between foundation wall and footer?
Sill sealer/foam sill gasket works pretty well (the same stuff you often see between the stem wall and mudsill)
this is such a good video
