What Is Crawl Space Drainage?
Crawl space drainage systems collect groundwater and seepage at the perimeter and route it to a sump pump before it can saturate soil, raise humidity, or reach the wood structure. APS Foundation installs these systems throughout Alabama as the first step in any moisture-management strategy where water intrusion is present. The system begins with a perimeter drainage channel, a slotted pipe or channel installed in a shallow trench at the base of the foundation walls. Water seeping through the walls or rising from the ground flows into the channel and drains to a sump pit. A submersible pump discharges water away from the structure. APS includes battery backup as standard equipment given Alabama's frequency of severe storms and power outages. Crawl space drainage addresses the water source. Encapsulation addresses the moisture vapor. Both together provide complete moisture management for Alabama crawl spaces.

Frequently Asked Questions
Is drainage different from encapsulation?
Yes. Drainage manages liquid water, groundwater seepage and surface water intrusion. Encapsulation manages moisture vapor and atmospheric humidity. Most wet crawl spaces need both.
Where does the sump pump discharge?
The discharge line is routed to daylight outside the foundation, typically to a sloped area of the yard away from the structure. APS designs discharge routing to prevent water from cycling back toward the foundation.
