Basement Waterproofing

Foundation Waterproofing

Basement waterproofing problems: with rain or from other sources such as irrigation or condensation, moisture can creep into your basement through your foundation walls or concrete ground slab.

Waterproofing failures can cause the following problems:

- Mold, mildew, vegetative growth and odors
- Stains and rust
- Deterioration of concrete or masonry that lead to serious structural damage
- Deterioration of carpet and wood rot
- Delamination of existing wall and floor coverings

Since your foundation is already under the ground and a new waterproofing on the outside layer of your foundation would be too expensive and time consuming, often the easiest way to waterproof your basement is by waterproofing the inside walls. In this case negative side pressure from water or vapor often causes for other products to delaminate and fail.
