Surface Drainage Solutions in Schertz, 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.

Schertz sits at the junction of three counties northeast of San Antonio, its growth shaped heavily by nearby Randolph Air Force Base alongside its position along the I-35 corridor connecting San Antonio and Austin. Guadalupe County sits at the edge of the Blackland Prairie where it transitions toward the South Texas Plains, producing clay-heavy soil that shrink-swells through the region's wet-spring, hot-summer cycle, somewhat less dramatically than the deep blackland clay found in the Dallas area but still a real factor for yard drainage, particularly given the base's steady cycle of incoming and outgoing military families and the maintenance patterns that turnover tends to produce. Schertz's predominantly newer slab-built subdivisions, developed from the 1980s onward as the city transformed into a genuine San Antonio-metro suburb, mean the local drainage picture is mostly about subdivision-era engineering quality rather than aging infrastructure. Randolph Air Force Base's own housing turnover cycle here mirrors the same pattern found in Killeen and Harker Heights near Fort Cavazos, just on a smaller scale.

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.
