Unlike basements, leaks in crawl spaces can go unnoticed for months, or even years, before being addressed. However, wet crawl spaces create a big problem with rot and mold, and that can lead to expensive repairs in the long term.

The answer is the WaterGuard® Drainage System. Its custom design includes holes on the top and front to accept water from the soil and surface of your crawl space. A special wall flange collects water from the crawl space walls and the footing/wall joint.

A clog-resistant, reliable crawl space drain

Crawl space drain

Our WaterGuard® system will keep your crawl space dry, ensuring your home's structural integrity.

The WaterGuard® is the ideal way to drain water in a dirt crawl space without clogging or drain failure.

All openings facing the dirt surface of your crawl space include a special filter fabric material, designed to allow water in while keeping mud and other clogging debris away.

As one component of our crawl space repair system, the WaterGuard® is a perfect match for our crawl space sump pump, drainage matting, and vapor barrier. Once installed, your home will be protected from mold and damaging rot, creating a healthier, protected home environment.
