rockmeupto125 Posted August 1, 2014 Share Posted August 1, 2014 I did some online searching but couldn't find anything specific for my situation, so I'll submit a plea to the experts here. I have a concrete patio that abuts the cinderblock foundation of my house. Unfortunately, the slope isn't quite right on the patio slab, and water can run to the joint between the patio and foundation. I'd like to seal that space with a spray or brush on sealer. Any suggestions? Quote Link to comment Share on other sites More sharing options...

rockmeupto125 Posted August 6, 2014 Author Share Posted August 6, 2014 There's really no gap, Rich. Its just the seam where the pad butts up against the block. There's certainly room for water, and that end of the basement was frequently damp. Quote Link to comment Share on other sites More sharing options...
jcrich Posted August 6, 2014 Share Posted August 6, 2014 Could you run a bead of some type of silicone or masonary/concrete caulking to seal that? Quote Link to comment Share on other sites More sharing options...
