Re: Waterproofing Question


Do you have a downspout or valley in the roof draining on that corner? Did they install new footer drains before backfilling? What did they use for wateproofing?

Re: Waterproofing Question


The gutters and downspouts aren't installed yet the siding contractor is working on that now I have a storm drain set up to receive the downspout. He used some sort of roll on product it was like a blue latex,

Re: Waterproofing Question


Report back once the gutters are installed. Most likely that’s the problem. Even though it’s just that one area that gives you a problem, moving the water away from the foundation stops this sort of thing.

Re: Waterproofing Question


Not sure I'd you can tell from the picture but there's no concrete or stone there I can literally see the backfill, I know it needs to be filled in I was just asking here for the best approach

Re: Waterproofing Question


did you say that it's a hole where you can see the backfill?!
if that's the case it really should of been filled prior to backfill

Re: Waterproofing Question


I'd pack everything full with hydraulic cement and see if it holds. Next step would be to address it from outside.

Re: Waterproofing Question


if it was someone else's house, dig from outside and water proof
my own house, probably hydraulic cement and the gutters
then see what happens before it gets finished
