Water that will not drain is one of the most common yard problems in Austin, and the soil is the reason. Much of east and central Austin sits on Blackland clay, which is 60 to 80 percent clay and very slow to let water soak in. So rain stays on the surface, the lawn turns soggy, and water pools against the foundation. That is more than a nuisance: the clay swells when wet and shrinks when dry, and that movement cracks slabs. A French drain solves the standing water at its source. It is a sloped, gravel-filled trench with a perforated pipe that collects water and carries it to a safe outlet away from the house. Thrive Landscape and Design is a veteran-owned, design-build landscaper with over 20 years installing yard drainage solutions across Travis, Williamson, and Hays counties, and we hold a 5.0 Google rating from 70+ reviews. We size every drain for Central Texas flash-flood downpours and pair it with grading and downspout drains so the whole yard sheds water. Most French drains run roughly $30 to $70 per linear foot, and every estimate is itemized and free. Our drainage approach follows the Travis County extension guidance on Austin-area soils and the City of Austin Development Services standards.

Our Process

Free On-Site Drainage Assessment
We walk the wet area with you and find the real source. We check where water enters, where it pools, and where it can safely go. We look at the grade, the downspouts, the soil, and the low spots. You get honest options, often a mix of a French drain and grading, and a clear, itemized written estimate with no pressure to decide on the spot.
Drain Design & Outlet Plan
We map the run, set the pipe size for your runoff, and plan the slope so water keeps moving. The drain needs a steady fall of at least about one inch for every eight to ten feet to the outlet. We decide where the water daylights or feeds a pop-up emitter, away from the house and the neighbor's lot, and we tie in downspouts and catch basins where they help.


Trench, Fabric & Gravel Bed
We dig the trench to grade, usually about 18 to 24 inches deep, and drill through caliche and limestone where we hit it. We line the trench with non-woven geotextile filter fabric so the clay cannot clog the drain, then lay a bed of clean angular gravel for the pipe to sit on. The fabric is what lets a French drain last for decades instead of silting up in a few seasons.
Perforated Pipe & Backfill
We set a perforated pipe in the gravel, holes down, on the slope we planned, then surround and cover it with more clean gravel. We wrap the fabric over the top so soil stays out, then backfill and connect the outlet, daylight or a pop-up emitter. For surface water at a patio or driveway we add a channel drain, and we tie roof downspouts into the underground line.


Restore, Test & Walk-Through
We restore the surface with sod, mulch, or rock so the drain blends in, then we run water through the line and watch it flow clean out the outlet. We walk the finished job with you, show you where the outlets are, and explain the quick yearly check that keeps it flowing. You end with a clean site and a yard that drains instead of pooling.

French, Area, Channel & Downspout Drains
Plus Grading That Sheds Water On Clay
Standing water rarely has one cause, so we rarely use one tool. Here is how the main drainage solutions we build compare for an Austin yard. We often combine two or three on a single lot, all sized for our flash-flood downpours.
Request A QuoteA French drain is a buried, gravel-filled trench with a perforated pipe that collects groundwater and soggy-lawn water along its whole length. An area drain is a basin with a grate set in a low spot to catch a pool of standing water. Both carry water to a clean outlet away from your foundation.
A channel drain is a long surface grate set in concrete, ideal for catching sheet water at a patio, driveway, or pool deck. Downspout drains tie your roof gutters into an underground pipe so storm water leaves the foundation zone instead of dumping next to the slab.
Sometimes the fix is the shape of the ground, not a pipe. Regrading sets a positive slope away from the house, and a swale is a shallow, planted low spot that carries surface runoff across a long Hill Country slope. We pair grading with a French drain when the clay holds more water than slope alone can move.


Why Choose Thrive Landscape and Design?
We Find The Real Source
A drain in the wrong place wastes your money. We trace where the water comes from before we dig, then fix the cause with the right mix of a French drain, grading, and downspout drains.
Built For Blackland Clay
Austin's clay holds water and barely lets it soak in, so a drain has to do the work the soil will not. We wrap every drain in filter fabric so the clay cannot clog it and it keeps flowing for decades.
Sized For Flash-Flood Rain
Central Texas sits in Flash Flood Alley, where two to four inches can fall in an hour. We size the pipe and slope for those peak downpours, not just a gentle rain, so the system keeps up.

Frequently Asked Questions
Sometimes regrading the yard solves the problem on its own, and it is usually the cheaper fix. Grading works when the ground simply slopes the wrong way toward the house. A French drain is the better tool when water collects in a low spot, sits against a foundation, or seeps from a slope and the grade cannot carry it away. On Blackland clay, water moves very slowly through the soil, so a drain often does the heavy lifting that grading alone cannot. We look at both during a free site visit and recommend only what your yard needs.
The clearest signs are standing water in the yard a day or more after rain, a soggy spot that never dries, water pooling against the foundation, and mushy lawn that ruts under foot traffic. You may also see mosquitoes in the wet area, soil washing out of beds, a damp crawl space, or water running across a patio. If you see two or more, especially on a low spot or at the base of a slope, a French drain is usually the answer. We confirm the source on site before we dig.
Most residential French drains in Austin run roughly $30 to $70 per linear foot installed, with the typical yard project landing in the low thousands. The big cost drivers are the length of the run, how deep we dig, how much rock we hit in caliche or limestone, the pipe size for your runoff, and where the water has to discharge. Tying in downspouts, adding catch basins, or pairing the drain with regrading adds to the total. Every estimate is itemized and free.
Blackland clay is 60 to 80 percent clay and water moves through it very slowly, so rain sits on top instead of soaking in. That is why yards on the central Austin clay belt stay soggy for days. A French drain gives that trapped water a fast path out. We dig a sloped trench, line it with geotextile fabric, set a perforated pipe in clean gravel, and carry the water to a daylight outlet or pop-up emitter away from the house. The drain works with the clay instead of fighting it.
Most yard French drains run about 18 to 24 inches deep, which sets the perforated pipe below the standing water with room for gravel under and over it. The exact depth depends on where the water sits, where it discharges, and how much rock we dig through. What matters more than a single number is the slope: the pipe needs a steady fall of at least about one inch for every eight to ten feet so water keeps moving to the outlet. We set depth and slope to your yard during design.
A French drain built the right way lasts for decades, often 30 years or more. The thing that shortens a drain's life is silt clogging the gravel and pipe, which is exactly what the geotextile filter fabric prevents. We wrap the gravel in non-woven fabric, use the correct pipe, and add a clean outlet so the system can flush itself. A quick yearly check of the outlet and a flush after big storms keep it flowing. Drains that fail early almost always skipped the fabric or the slope.
A French drain is buried and best for groundwater, soggy lawn, and water seeping from a slope, since it collects along its whole length. A swale is a shallow, planted low spot that carries surface runoff and works well on long Hill Country slopes. A channel drain is a surface grate set in concrete, ideal for a patio, driveway, or pool deck. Many Austin yards use a mix of all three. We pick the right one, or the right combination, for your lot.
Yes, when it is part of a full drainage plan. On Blackland clay the soil swells when wet and shrinks when dry, and that constant movement is a leading cause of foundation cracks and slab heave in Central Texas. A French drain pulls water away from the soil right next to your slab so the moisture stays more even. We pair the drain with proper grading and downspout extensions so roof and surface water also leave the foundation zone. Keeping that water moving is one of the best ways to protect a slab on clay.
