Interior Foundation Footing Drain for Crawl Space

Typical interior foundation footing drains involve excavating a shallow trench around the inside of your foundation below the footing elevation and sloping it to the lowest level of the crawl space. Perforated pipe is installed in the trench and surrounded with drain rock. The piping is connected to a catch basin (drain) installed at the lowest point of the crawl space. Depending upon the topography, the collected water is drained out by gravity or is mechanically pumped to the appropriate outlet source like a storm drain system.

To finish the solution, the entire crawl space is cleaned of any construction debris, and the surface is covered with a vapor barrier to keep humidity in the crawl space reduced to ambient levels.
