Hi Everyone,
Here I have a basement ready for a reno and i'm needing to address the concrete slab. as you can see by the pics there are some spots where moisture is coming in. I believe these to be small cracks at the seam of the slab and wall. I believe the problem is a couple of things, the grade of the yard sloping toward that corner of the house, crack forming after 70 years and no VP under the slab. I'm going to address the grading issue and possibly put a sealant on the outside of the house while I have things dug up. My questions are:
1. can I seal any of these cracks on the inside in the mean time (the black you see is my experiment with unsanded grout i had left over - it actually made a bit of an improvement!).
2. what is the best way to avoid water vapour seaping up from the concrete floor. Should I use a silicone sealant, poly vinyl or both?
btw, the water coming in is only on one side of the house.
