Waterproofing Foundations

Waterproofing Crawl Spaces and Basements

Summary: Waterproofing basement foundation walls and waterproofing crawl space foundation walls is critical for a dry basement or crawl space.

The finished foundation should be waterproofed from the footing to the finish grade line.

I recommend hiring a professional waterproofing contractor for this.

Waterproofing contractors are listed in the Yellow Pages under Waterproofing, or your foundation contractor can probably recommend one. A professional company will stand behind its work.

Also, depending on your locale, you may need to have the soil treated for insects and pests, particularly termites. Again, hire a professional.

Note: The soil treatment is done after the foundation is in, but before any concrete is poured for either basements, porches, or a garage.

The foundation wall for any type house besides being waterproofed, needs to be high enough so that water can be diverted away from the house by the final grade of the soil around the house.
