Well, 54 inches deep and I found the problem with my basement. The caulk seal around my water main had given way.
It is all cleaned and prepped with a wire brush, but I want to seal it "the best" method and could use some advice.
I think my options are as follows.
1. Dryloc Fastplug Hydraulic cement.
2. Epoxy putty
3. More Caulk
Dryloc wall sealer over top of all of the above.
