Waterproofing paint for exterior walls
Keep basements and crawl spaces dry with effective waterproofing techniques
The goal of keeping a basement or crawl space dry is an important one. You need a waterproof foundation if you plan to use the basement as living space. But foundation waterproofing is necessary even in unused basement and crawl space areas because high moisture content causes mold to grow on organic materials like wood, fabric, paper and latex paint. Mold not only destroys materials; it also fills the air with hazardous mold spores.
Each waterproofing technique has distinct Pros & Cons
There's been a great deal of controversy about the effectiveness of different foundation waterproofing techniques. Advocates of exterior foundation waterproofing stress the value of an impermeable membrane barrier applied to the exterior of foundation. These people agree that the best time for this approach is during new construction when freshly built foundation walls are exposed.
Once the foundation walls are covered with dirt, installing an exterior waterproof coating or membrane becomes prohibitively expensive and much more disruptive if the house is occupied.
Special coatings are also available for waterproofing foundation walls from inside the foundation. The trouble with waterproof paint is that it rarely works when the ground stays wet and there's significant hydrostatic pressure against foundation walls. Moisture traveling through the foundation wall from outside typically leaks through the paint film or causes it to bubble or peel, admitting water into the basement or crawl space.
Interior drains and a sump pump harness water pressure instead of fighting it
Instead of attempting to hold back a large, high-pressure volume of water, interior French drains take a different approach to foundation waterproofing.
Installed just inside the foundation walls, this drainage system captures water before it reaches the basement or crawl space floor and directs it to a sump pump. The pump automatically ejects water to the exterior when water reaches a preset level in the sump pit. Thanks to advanced sump pump technology pioneered by Basement Systems, this active waterproofing system has proven to be very effective in keeping basements and crawl spaces dry.
