French Drain Installation in Columbia, TN
A gravel trench and perforated pipe that intercepts water moving through the ground and carries it somewhere it can leave.
A french drain is a trench filled with washed stone around a perforated pipe, wrapped so that soil cannot migrate into the voids. It works by giving subsurface water an easier path than the clay around it. That is the whole principle, and it is why depth and slope decide whether one works: too shallow and the water passes underneath it, too flat and the pipe holds water instead of moving it.
The parts that get skipped are the parts that fail. Washed stone rather than crusher run, because fines clog the voids within a season. Filter fabric around the stone rather than wrapped tight around the pipe alone, because a sock filled with silt is a plugged drain. And a real outlet, either to daylight on falling ground or to a pop-up emitter, because a drain with nowhere to go simply fills up and stays full.
Typical cost: $25 - $60 per linear foot installed, so most residential runs land between $2,000 and $6,000
When french drain installation is the right call
- Water stands in the same low spot for a day or more after rain
- A hillside above the house sends sheet flow toward the foundation
- The ground stays soft and spongy long after everything else has dried
- Water shows up against a wall or under the house with no obvious surface source

Common questions
How deep should a french drain be?
Deep enough to sit below the water you are trying to catch, which usually means somewhere between eighteen inches and three feet. A drain laid a few inches under the sod intercepts almost nothing, and that is the most common reason a homeowner tells you french drains do not work.
How long does one last?
A properly built drain with washed stone and fabric can run for decades. One built with the wrong stone, or with fabric wrapped only around the pipe, can silt up within a few years. The difference is entirely in the build, not the product.
Can I put one in myself?
The digging is straightforward. The slope is not. A run needs consistent fall along its whole length, and getting that wrong by an inch over thirty feet is the difference between a drain and a buried trough. Rent a laser level if you are attempting it.
