yeah i’m no lawyer, get that out of the way lol
1:45 - am not sure but it appears as though i can see a BLACK membrane sticking up a TAD along bottom of foundation wall/basement floor perimeter, ya see that?
IF that was the builders supposded ‘remediation’, their solution to the water problem in basement then imo they may have a problem.
again, BEST thing to do with leaky basement is, first IDENTIFY the problem (s), yes, sometimes in some homes/basements there is more than 1 way water is getting in so, need to be able to SEE the walls etc and at 1:45 one cannot see the this wall so i ask, did builder REMOVE the crap on the wall to deduce if water is entering through 1 or more rod holes and-or 1 or more cracks in wall, dig?
another ‘point’ is, installing any INT basement drainage system doesn’t stop water from entering through rod holes, cracks in walls, windows etc.
so i ask again, did the builder bother to… remove the junk off the F wall (s) where the water was getting on basement floor OR, lol did the builder just install some bogus INT system OR, did he just raise n slope the grade… crap like that
