Relieve Water Pressure Behind Your Wall Before It Fails
Proper retaining wall drainage in Austin prevents water pressure from building up behind your wall, one of the leading causes of leaning, bulging and failure. Soil that becomes saturated is heavy, and without a path to escape, water pushes against the wall with tremendous force. A drainage system behind the wall relieves that pressure and keeps the structure stable for decades. Good drainage costs far less than rebuilding a wall.
We install perforated drain pipe, clean gravel backfill, filter fabric and weep holes where needed, routing water to a safe discharge point. Whether you are building a new wall or repairing an older one, good drainage extends its lifespan and protects the slope around it. Our team handles all the details very carefully and cleans up after the job. Contact us today for a free estimate on retaining wall drainage.
What Causes Walls to Fail
When rain saturates the soil behind a retaining wall, water with nowhere to drain presses against the back of the structure. That hydrostatic pressure grows with every Austin downpour until the wall starts to lean, bulge, or crack. Good drainage removes the water so that pressure never gets a chance to build.
How We Drain a Wall
We place a perforated drain pipe along the base behind the wall, surround it with clean gravel, and separate that gravel from the soil with filter fabric so it doesn't clog. Weep holes through the face give water a direct path out, and the pipe carries the rest to a discharge point away from the wall.

Frequently Asked Questions
What are weep holes and why does my wall need them?
Weep holes are openings through the face of a wall that let trapped water escape. Combined with gravel and a drain pipe behind the wall, they relieve the hydrostatic pressure that would otherwise push the wall out of place.
Can you add drainage to an existing retaining wall?
Often, yes. We assess the wall's condition and construction, then excavate behind it to add drain pipe, gravel, and weep holes where feasible. If the wall is already badly compromised, we'll be honest about what drainage alone can and can't save.
