Basement Waterproofing Photo Album: Leaky Basement Crack Repair - London, ON

A crack off the corner of a window in a poured concrete foundation is very common. We see and repair these multiple times a day at Advanced Basement Systems! Our patented product, Flexi Span, uses a three-layer system with a drainage pocket to offer a 25-year warranty on the home. When the basement is going to be finished or re-finished, we cover the repair in a forth layer, which is our ThermalDry Wall- that's the silver product you see in the photos.

Remove Insulation

The pink fiberglass insulation be absorbing water. We pull it aside to expose the crack.

Outside of Foundation

You can see the crack coming off the window corner. The window opening is a structural weak point, and although relatively insignificant, it often causes the immediate concrete to crack.
