Surface Drainage Solutions in Seguin, TX

Water that flows across the surface of your yard can cause significant damage if it's flowing toward the house instead of away. Surface drainage solutions — including regrading, swale construction, and berm installation — redirect that flow so it exits the property without threatening the foundation or creating erosion problems.

Seguin sits along the Guadalupe River in Guadalupe County between San Antonio and Austin, one of the oldest Anglo settlements in Texas, whose historic downtown square carries housing and drainage infrastructure dating to the mid-1800s. Guadalupe County sits at the edge of the Blackland Prairie where it transitions toward the South Texas Plains, and the Guadalupe River's floodplain running directly through the city adds real river-adjacent drainage considerations beyond the ordinary clay shrink-swell cycle found in most of Central Texas. Seguin's economy today blends manufacturing (Caterpillar and other industrial employers operate here), agriculture, and a growing bedroom-community role as the San Antonio-Austin corridor continues to develop, with the city's older river-adjacent core showing notably different drainage conditions than its newer subdivisions farther from the water. The Guadalupe River's own flood history through Seguin is a documented, recurring civic concern distinct from the ordinary clay drainage issues found away from the riverbank.

Regrading and Swales

Many drainage problems are the result of incorrect grading — either from original construction, soil settlement, or landscaping that has changed the surface contours over time. We connect you with contractors who regrade problem areas to restore positive drainage away from the home. In some cases, a swale — a shallow, vegetated channel — is the right solution for directing concentrated flow across the property safely. Correct grade is a small number that matters a lot: a slope of even a few percent away from the foundation over the first several feet is usually enough to keep water moving in the right direction, but a yard that's flat or, worse, sloping the wrong way needs real regrading, not just a cosmetic fix.

• Regrading near the foundation — restoring positive slope away from the house over the first 6-10 feet, the single highest-impact surface fix on most properties.
• Swale construction — a shallow, vegetated channel that carries concentrated flow safely to a discharge point without underground pipe.
• Berms — low earthen ridges that redirect water around a structure or feature rather than through it.
• Re-establishing lost grade — common on older properties where years of landscaping, mulch buildup, or soil settling have quietly erased the original drainage slope.

What Surface Drainage Can and Can't Solve

Surface drainage works well when the problem is water running across the yard toward the house. It's less effective for subsurface water that rises from below or migrates through the soil. In those cases, surface drainage is often combined with french drains or catch basins. A provider assesses the full drainage picture before recommending any single solution. A simple way to tell which type of problem you likely have: surface issues usually show up quickly during a storm, with visible flow you can watch happen, while subsurface issues tend to show up later, as dampness or pooling that appears well after the rain has stopped.

• Solves well: water visibly flowing across the yard toward the house during rain.
• Solves well: erosion channels or bare dirt paths where surface runoff repeatedly follows the same route.
• Doesn't solve alone: dampness or pooling that appears hours after rain has stopped, more likely subsurface.
• Doesn't solve alone: water reaching a basement or crawl space from below rather than over the surface.
