Crawl spaces traditionally have a bare dirt bottom, though some have gravel or concrete. Regardless, ground moisture is constantly being drawn upward out of the ground to evaporate. The resulting vapor can condense on the wood subfloor and other surfaces in and above the crawl space, resulting in a significant risk of mold and wood rot. This poses a threat not just within the crawl space itself, but can also threaten the interior of the house, as moisture works its way upward into and through the walls and subfloor. It also creates a great breeding ground and home environment for pests.
In the early days of home building, the only practical way to minimize damaging moisture in a crawl space was to vent it. But venting has a lot of practical limitations. Today, encapsulating a crawl space (a process that includes draining, drying, and sealing it off) is the best way to prevent this ever-present threat to your home’s structural and aesthetic integrity.
Crawl space encapsulation systems use three main steps and components to dry out the crawl space and make sure it stays that way, preserving the life and investment in your home. Our Atlanta crawl space drains are designed and engineered specifically for crawl spaces and the conditions they typically house.
The drainage system is installed around the perimeter, below the dirt grade of your crawl space. It is graded so that collected water flows downward toward a specially designed, low-lying, and submerged sump pump, designed specifically for crawl spaces. Our drainage system has holes along the top and sides to collect water from the surrounding ground and the side walls of the foundation.
When installed with a crawl space encapsulation system, the drainage system can keep water out of the crawl space. 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.
