Excavation and removal of built-up sediment to restore a detention pond's designed storage, drainage performance and access.
Detention ponds around Wimberley carry more sediment load than their original design ever accounted for. Between the cedar and limestone hillsides that ring Woodcreek and the creekside lots near Cypress Creek and Blue Hole, rain does not soak into the ground so much as run off it, and that runoff brings fine soil with it every time. Corral Bros handles the excavation and cleanout that gets a basin back to its designed storage and drainage performance.
The signs show up the same way across most of the properties we look at here. A forebay silts in first and fastest, since it is built to catch the heaviest sediment before it reaches the main pool. Drawdown slows after storms because the basin simply holds less water than it was built to hold. On older sites you will find bare, eroding slopes where grass never established on thin soil, volunteer cedar and oak seedlings taking root in an embankment that should stay clear, or an outlet structure partly buried and barely functioning. Shallow topsoil over limestone does not give sediment anywhere to go but into the pond.
Working with us starts with a free on-site estimate, usually set up within 48 hours of your call. We walk the pond with you, check sediment depth at the forebay and the main basin, and look at the outlet before we quote anything. Once the scope is set, we excavate and haul the material offsite, restore the design grade, and clean out the forebay and outlet so the system drains the way it was built to. We are licensed and insured, locally owned, and we handle both the HOA-run basins and the larger commercial sites along the I-35 corridor and into the Hill Country.
We're a local, family-built company that treats your Wimberley property like our own, tidy crews, clear pricing, and detention pond sediment removal that holds up to Hays 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, and walk the basin with whoever manages the property, often the HOA board member or the community manager on record. We check the forebay, the outlet structure, and probe sediment depth in a few spots to see how much storage the pond has actually lost. You get a straightforward number before anything else happens.
It depends on the watershed above it, but thin Hill Country topsoil over limestone means heavy rain carries a lot of fine sediment fast. Ponds serving older developments or sites with disturbed upslope ground often need cleanout sooner than the original design assumed. Slow drawdown after a storm, standing water that used to drain, or a visibly shrinking wet pool are the usual signs it is time.
Yes. Most detention basins in Wimberley sit at the edge of a property away from building entrances, so we stage equipment and hauling to keep drive aisles and resident parking open. We coordinate timing with the property manager or board ahead of the work, and if the pond sits near a shared amenity like a trail or common area, we plan access around it instead of through it.
Shallow soil over limestone and cedar cover on the hillsides around Wimberley mean a lot of silt and organic debris washes into basins during heavy rain instead of soaking in upslope. That sediment tends to pile up fast in the forebay and settle fine silt further into the pond, which is why outlet structures here clog more than owners expect for the pond's age.
The biggest factors are how much sediment has accumulated, how far it has to be hauled offsite, and how accessible the pond is for equipment given Wimberley's wooded lots and limestone terrain. A pond with a badly silted forebay or volunteer trees grown into the embankment takes more time than a basin that just needs routine cleanout. We lay out the scope clearly after the site walk so there are no surprises.
