French Drain Installation
in Charlotte, NC

A french drain is a trench that gives water an easier path than the one it is taking now. Stone and perforated pipe go in below grade, water in the surrounding soil moves into the stone because stone offers less resistance than packed clay, enters the pipe through the perforations, and runs downhill to an outlet.

Everything about whether it works comes down to two things: whether the trench actually intercepts the water, and whether the outlet is lower than the inlet by enough to keep water moving. Neither is about the pipe.

When a French Drain Is the Right Answer
Not every wet yard needs one.

Water pooling in a shallow low spot after rain and drying out within a day is usually a grading problem. Recutting the fall costs less and solves it outright.

A yard that stays saturated for days, a slope that pushes water toward the house every storm, a strip along a fence line that never dries — those are the cases where a drain earns its cost. The same goes for water coming off a neighbouring property uphill, where regrading your own yard just moves the problem to a different corner of it.

Which one applies comes out of walking the property and tracing where water enters, where it collects, and where it could reasonably go. That happens before anything is quoted.
How the Line Is Built
The trench is cut twelve inches wide and between eighteen and twenty-four inches deep, with the depth set by how far the line has to run and how much fall is available across that distance. A drain needs continuous downhill grade from end to end — a line that flattens in the middle holds water and silts up from that point.

The trench is lined with filter fabric across its full width, wrapping the entire stone section rather than sleeving the pipe alone. This is the part that determines lifespan. Clay fines migrate into stone under water pressure, and once the voids between stones fill with silt the drain stops draining. Wrapping the trench keeps soil out of the whole stone body, not just out of the pipe.

Perforated rigid PVC goes in on a bed of stone. Rigid pipe holds its grade — corrugated pipe follows the shape of the trench bottom and develops sags that trap water and collect sediment. It also has a smooth interior, so flow is not slowed and there are no ridges for silt to settle behind.

Washed granite stone backfills the trench around and over the pipe. Washed matters: unwashed stone carries its own dust and fines, which is the same problem the fabric is there to keep out, introduced from the inside.

The fabric is folded over the top before the trench is closed.
Where the Water Goes
This is where drains fail most often, and it gets settled before excavation rather than after.

Water is taken either to a daylight outlet at the road, or to a natural low point or ditch on the property where it can discharge without collecting. Both need the outlet to sit low enough relative to the inlet that gravity carries the flow the whole way.

A drain that runs to a point no lower than where it started is a buried reservoir. If the fall across the site does not work, the honest answer is a different solution, not a longer trench.
Clay Soil
Charlotte’s red clay changes the calculation in two ways.

It drains slowly, so water sits in the soil rather than passing through it. That makes the drain more necessary, and it also means the line works by intercepting water at the trench face rather than by drawing it in from a distance — which is why where the trench runs matters more here than how long it is.

The second is what clay does to the stone. Its fines are fine enough to travel with moving water and settle in the voids between stones, which is the failure mode the full-width fabric and the washed stone are there to prevent. In sandier ground a line built without either might last; in Piedmont clay it will not.
The Finished Surface
A line that crosses a lawn is graded so the finished surface sits flush rather than settling into a visible depression over the following months. Along a bed or fence line the stone can be left open at the surface instead, which lets water enter directly rather than having to pass through a soil layer first.
Drainage Before Hardscape
Where a patio, driveway or wall is planned on the same property, the drainage goes in first. A hardscape surface built over ground that holds water moves with that ground, and a drain run afterwards means opening up work that was already finished.

On properties where both are in scope, they are planned as one project with the drainage sequenced ahead.
Scope
The work covers drainage across the property — yard, slopes, bed lines, and roof water routed away from the house. Waterproofing systems against the foundation itself sit outside what we take on.

Frequently Asked Questions
— How long does installation take?
— Two to four days for most lines, depending on length, depth, and how far the outlet sits from the collection point.
— Will it clog over time?
— That depends on how it was built. Silt entering the stone is what clogs a drain, so fabric across the full trench and washed stone are what prevent it. Lines built without either fill with clay fines within a few seasons.
— Does it need maintenance?
— The outlet is the part to keep an eye on. A daylight outlet can get blocked by leaves, mulch or grass growing over it, and a blocked outlet backs the line up. Checking it once or twice a year is the whole maintenance requirement.
— How deep does the trench need to be?
— Between eighteen and twenty-four inches for most lines. Depth is driven by the fall available across the run rather than by a standard figure — the line has to keep dropping the whole way to the outlet.
— Can it go under a lawn, or does the stone have to show?
— Either. Across a lawn the trench is closed with soil and turf and the line is invisible. Along a bed or fence line, leaving stone at the surface lets water enter directly.
— What does a french drain cost?
— Length is the main driver, along with trench depth, how much the ground has to be cut through, and how far the outlet sits from the water. A short line to a ditch at the property edge is a different project from one crossing an established lawn to reach the road.
