Crawl Space Drainage Systems
Engineered drainage solutions that capture and redirect water before it damages your home.
What is Crawl Space Drainage Systems?
Crawl space drainage systems are engineered to manage water intrusion from groundwater, surface runoff, and soil saturation. Interior French drains, channel drains, sump pits, and discharge lines work together to capture water at the perimeter and lowest points of your crawl space, then pump it away from your foundation. Proper drainage is often the critical first step before encapsulation in homes with active water problems.
Key Benefits
- Eliminates standing water and puddling
- Prevents foundation erosion and settling
- Prerequisite for successful encapsulation
- Protects against flooding during heavy rain
- Reduces hydrostatic pressure on foundation walls
- Battery backup options for power outage protection
Our Process
Assessment
Water flow patterns, soil type, groundwater levels, and drainage needs are evaluated.
Trenching
A trench is dug along the interior perimeter of the foundation to house the drainage pipe.
Drain Installation
Perforated drainage pipe is laid in the trench, surrounded by gravel for filtration.
Sump Pit & Pump
A sump pit is installed at the lowest collection point, equipped with a primary pump and optional battery backup.
Discharge Line
A discharge line routes collected water safely away from the foundation to a designated drainage area.
Typical Cost
