French Drain Installation in Waco, TX

A french drain is a gravel-filled trench with a perforated pipe that intercepts groundwater and surface runoff, then routes it away from your yard or foundation. When properly designed for your soil type and installed with correct slope and filter fabric, a french drain is one of the most effective long-term drainage solutions available. We install french drains for homeowners throughout Waco and McLennan County.

How French Drains Work — And Why Installation Details Matter

Water follows gravity. A french drain works by providing a path of least resistance — the gravel trench allows water to enter from surrounding soil, where the perforated pipe captures it and directs it to a discharge point. The variables that determine whether a french drain works long-term are slope (minimum 1% grade for flow), filter fabric selection (prevents soil from migrating into gravel and blocking the pipe), and outlet placement. A drain installed without adequate slope or with the wrong filter fabric will fail within a few years.

Common French Drain Applications in McLennan County

We install french drains along foundation perimeters to intercept water before it reaches the structure, across yards to interrupt subsurface water flow toward the home, and in low-lying areas where water consistently pools. In McLennan County's clay soils, filter fabric selection is especially critical — clay particles are fine enough to migrate through coarser fabrics and eventually clog the drain.
