French Drain Installation, explained.
A French drain is a trench lined with filter fabric, filled with clean stone and fitted with a perforated pipe that lies on a bed of stone. Water in the soil moves toward the stone, enters the pipe and flows downhill to an outlet. It works by giving water an easier path than the soil provides.
We dig the trench with a steady fall toward the outlet, line it with fabric, set the pipe on stone, cover it and wrap the fabric over the top before the final layer goes in. Details matter: grade, stone size, fabric type and a clear outlet are what separate a drain that works for years from one that clogs in a season.
Signs this service fits
- Water seeps toward a wall or into a basement
- A slope sends groundwater to the lawn
- A wet area stays soggy even without a low spot
- A retaining wall needs drainage behind it
A good fit, and what to know.
We would rather you hear the limits from us than discover them later.
A good fit when
- Groundwater, not just surface runoff, is the problem
- A downhill outlet is available
- You want the water managed with limited visible change
Worth knowing
- A French drain does not fix a leaking roof, a failing foundation or an outlet that does not exist
- On flat lots, a pumped system may be needed
Why do it this way.
Intercepts groundwater
Placed across the water’s path, it catches it before the house.
Continuous fall
Slope carries water to the outlet.
Clean stone and fabric
Reduces clogging from soil fines.
A defined outlet
Water exits at a stable, planned point.

How deep is a French drain?
Depth depends on where the water is and where the outlet is. It must be deep enough to catch the water and shallow enough to drain by gravity.
Do French drains clog?
Any drain can clog over time. Clean stone, filter fabric, correct grade and a clear outlet greatly reduce it, and cleanouts help maintenance.
Where does the water go?
To a lower point on your property such as a swale or storm outlet, or to an approved discharge. We plan the outlet before we dig.
