Abstract:
1. I have a crack in a foundation wall that starts from the corner of a rectangular penetration and runs almost vertically down the height of the wall. After a heavy rain, water leaks into the foundation through the crack. When contacted about needed repairs, one contractor recommended injecting epoxy into the crack, and another recommended injecting polyurethane. Which one will give the best repair?
2. We have to repair some thin delaminations on a concrete slab. What types of products work best for this application?
