Foundation waterproofing is applied to the exterior walls of a foundation, most often during construction of the building. Waterproofing forms a barrier that stops water from entering the interior of the basement.
Foundation waterproofing must do TWO things:
1. Stop water under hydrostatic pressure
Hydrostatic pressure is the force that ground water in the soil exerts against the foundation wall. It is possible for this pressure to force water and water vapor through a foundation wall. The more water that is in the soil the greater the hydrostatic pressure there will be. Also, the deeper the foundation is, the greater the hydrostatic pressure.
2. Span cracks in a foundation
Shrinkage cracks form in foundations as the concrete cures. This is a natural process that occurs in all foundations. Therefore, a waterproofing product must span these cracks to maintain an impermeable membrane against the moisture.
We install a variety of waterproofing products, which include sump pumps and drain systems, to help with keeping this area underneath your home dry, safe, and sustainable.
