Hello all,
I'm in a bit of a bind: we're about to start the process of finishing our basement (poured concrete foundation). It currently has a crack a that leaks a trickle of water during severe storms.
We have a company coming next week to seal the crack. Yesterday, however, we had a nice storm drop 3" of rain down, which revealed several concrete ties that were also leaky (nothing accumulating on the ground, but the dampness was obvious.
I can improve exterior grading to an extent, and the gutters already flow away from the house.
I'm tempted to install a dimpled membrane and drain it under the slab: it seems like a ton of work, but it seems like a nice insurance policy short of digging up the foundation and fixing the exterior.
What are the thoughts here? Is that necessary? Or would fixing the tie leaks be enough?
I was planning on using closed cell spray foam as well...not sure if that is compatible with the membrane, or if the foam will provide water barrier itself.
Another idea was putting small weep holes into the slab, applying spray foam insulation; and installing a sump pump? (There's about 8" of gravel under the slab)
