Understanding French Drain Systems
How Our Advanced Drainage Systems Work
A properly installed French drain is an engineered water management system consisting of:
- Premium Perforated Pipe (4″ or 6″ diameter, Schedule 40 PVC for longevity)
- Washed Drainage Gravel (¾” clean stone for optimal water filtration)
- Geotextile Fabric Barrier (Prevents soil clogging and system failure)
- Precision Slope Grading (1% minimum slope for proper water flow)
We offer both exterior perimeter drains and interior basement/crawl space drainage systems, each tailored to your property’s specific needs.
The Risks of an Unprotected Basement
Water in your basement creates more than just puddles—it leads to serious home health hazards:
Dual-Filter Design
Our proprietary fabric/gravel combination prevents 99% of sediment buildup
Freeze-Resistant Installation
Proper depth placement prevents winter system failure
High-Capacity Design
Systems handle up to 25 gallons per minute (GPM) of water flow
