Excavation and Waterproofing
At Edmonton Foundation Repair, we specialize in excavation & waterproofing of foundation walls. When your house was being built, it most likely had a damproofing spray applied. It's applied to the exterior, and sometimes it's also applied to the interior. Unfortunately, it's a very low performance, minimum requirement in the Alberta Building Code and is intended to slow (but not stop) water infiltration. This can lead to basement leakage. Cracks and other defects in the wall can contribute to leakage. We apply only premium quality elastomeric waterproofing to foundation walls, which will stop water infiltration. Whenever possible, we utilize waterbased (low VOC) waterproofing which is safer for the environment and our workers.
