Repair and stabilization of eroded pond slopes, embankments and channels using grading, soil stabilization, vegetation or riprap.
When the embankment on your detention pond starts sloughing off or a channel cuts deeper after every storm, the HOA board or property manager is the one the county and the association members will call, not the original developer. That responsibility lands on whoever holds the deed or manages the property today, and Bexar County inspectors do not care who built the basin in the first place. Corral Bros handles detention pond erosion repair for properties across San Antonio, from Alamo Heights to Stone Oak to Shavano Park.
San Antonio ground does not forgive a lazy design. Caliche and limestone shelves sit close to the surface on a lot of these sites, so water that should soak in in sheets moves across hardpan, cuts rills down the slope, and dumps silt into the forebay faster than anyone expects. Add the way Hill Country rain comes in hard, short bursts after weeks of dry weather, and you get bare slopes where grass never took root, volunteer trees working their roots into an embankment, and outlet structures half buried in sediment. Older in-town lots and newer Stone Oak subdivisions fail in different ways but for the same root cause: the basin was never built or maintained for this soil and this rainfall pattern.
Working with Corral Bros on this starts with a walk of the basin, not a quote off satellite photos. We look at slope angle, where the water is actually running versus where the plans say it should run, and whether the outlet structure is doing its job. From there the work is regrading, stabilization, riprap or matting, and seeding, done to match your property engineer's plan where one exists. You get a crew that shows up when scheduled and leaves the basin functioning the way it is supposed to.
We're a local, family-built company that treats your San Antonio property like our own, tidy crews, clear pricing, and detention pond erosion repair that holds up to Bexar County conditions. Available as a one-time project or part of an ongoing plan.
We schedule a free on-site visit, usually within 48 hours of your call, and walk the full basin with you or your maintenance contact. We look at slope condition, the forebay, outfall and any channel erosion, then give you a scope and estimate based on what the pond actually needs, not a flat per-acre number.
It depends on the soil and slope, but a lot of San Antonio basins need some repair work every few years once bare patches or rills show up. Caliche and limestone shelves shed water fast instead of absorbing it, so erosion tends to show up sooner here than in basins built on deeper topsoil.
Usually it is a visible sign: a silted-in forebay, water standing longer than it used to, a slope losing grass cover, or a channel that has cut a foot deeper than it was last year. An association inspection or a GC closing out a site before handover will also flag it.
We stage equipment and materials to keep drive lanes and parking open wherever the basin layout allows, and we coordinate timing with property management for apartment and retail sites. Most detention pond work happens along the perimeter of a property, away from building entrances and resident foot traffic.
Slope length and steepness, how much of the embankment is bare versus holding some vegetation, whether the outlet or channel needs structural repair, and access for equipment all factor in. A basin with exposed limestone or heavy caliche sometimes needs more soil stabilization work than a straightforward regrade and seed job.
