Waterproofing corners where basement floor and wall meet?
We're moving toward finishing our basement (2x4 framed, insulated, drywall, etc). We've had some minor seepage issues in the past and are taking a multi pronged approach to water management; we're making a lot of progress. (Significant regrading outside away from house; heavy-duty plastic sheeting attached to house to five feet out covered with mulch; new window wells with covers; sanded interior cinderblock walls that will get new coats of drylock).
In a recent rain, however, I noticed a couple of places where there was a small amount (about one foot long) of dampness where the floor meets the wall. I'm going to redo the plastic (upgrade to 20-mil and double attach to side of house), but I was wondering if anyone would/could recommend some kind of sealant that works particularly well at this intersection of basement wall and floor?
