Underground Drainage and Water Table Control in Austin
Reliable subsurface drainage in Austin removes excess groundwater from beneath your lawn, patio or foundation, where surface solutions cannot reach. Saturated soil can heave slabs, weaken retaining walls, flood crawl spaces and keep yards soggy for days after rain. Subsurface systems use buried perforated pipe, gravel and filter fabric to collect underground water and carry it away, keeping the soil stable and the ground dry. Prevent problems before they start.
Our team evaluates soil conditions and water flow, then designs a system with the right depth, slope and outlet for your property. We install quality pipe and drainage rock carefully, then restore the surface neatly. Whether you are protecting a new build or fixing an existing problem, our work helps prevent long-term structural damage. We build to last. Subsurface drainage also works hand in hand with your septic system. Regular septic tank pumping keeps the tank from overflowing into your drain field, which prevents saturated soil that can overwhelm underground drainage lines and leave your yard soggy.

How It Works Below Grade
We install perforated pipe in gravel-filled trenches at a depth chosen for your soil and water table, wrapped in filter fabric to keep sediment out. Water in the surrounding soil flows into the pipe and is carried off to a lower outlet or collection point. By drawing that water away, the system keeps the soil below your structure drier and more stable.
When You Need It
Persistent dampness in a crawlspace, soil that stays saturated long after the surface dries, or foundation movement tied to wet ground all point to a subsurface issue. Austin's clay holds moisture deep, so surface fixes alone often aren't enough. Lowering the water table addresses the problem at its source.

Frequently Asked Questions
How is subsurface drainage different from a French drain?
A French drain is one type of subsurface drainage, typically targeting a specific wet area or water against a foundation. A full subsurface system is broader, designed to lower the overall water table across a saturated area. We recommend whichever fits your situation.
Can lowering the water table really help my foundation?
Yes. Austin's expansive clay swells and shrinks with moisture, and that movement is what stresses foundations. Keeping the soil below your home at a stable, drier moisture level reduces that cycle and the strain it puts on your slab.
