Basement Waterproofing - Waterproofing a finished space
Here's what we did:
- We removed the mouldy drywall and the damaged area of the wall joists on all the walls where water penetrated.
- We created an in-floor drain to move any water into their updated sump pump system.
- Behind the walls we installed a thermal vapour barrier which serves two purposes, 1) it helps move any leaking water into the drain below and 2) helps improve the home's comfort as a thermal barrier.
- We then sistered the existing joists with waterproof steel joists.
