Cleaning, mowing, grading, vegetation control, debris removal and erosion repair for drainage swales, channels, ditches and culverts.
Getting equipment into a drainage channel at an occupied retail center or apartment community means working around parked cars, foot traffic and tenant schedules, not just around the water. Swale, channel and culvert maintenance in San Antonio has to happen on a live property, and that constraint shapes how we plan every visit, from Alamo Heights to the newer sections of Stone Oak.
San Antonio's caliche soils and limestone shelves do not drain the way engineers on wetter sites might expect, so water sits longer than the plan assumed. That slow drawdown lets sediment settle out in the forebay, lets Bermuda and native grasses take over a swale bottom, and gives volunteer hackberry and mesquite a foothold on embankments within a season or two. On older Bexar County lots we often find a culvert outlet half buried in silt from years of runoff; on newer Stone Oak builds we more often find bare, eroding slopes that never got established cover.
Working with Corral Bros on this scope means one point of contact who walks the system with you, tells you what is actually causing the slow drain or the bare patch, and handles the cleaning, mowing, grading and erosion repair without turning it into a multi-vendor project. We are locally owned, licensed and insured, and we schedule most on-site estimates within 48 hours so your board or your tenants are not waiting weeks for someone to look at a problem that is already visible from the parking lot.
We're a local, family-built company that treats your San Antonio property like our own, tidy crews, clear pricing, and swale, channel & culvert maintenance 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, and walk the swale, channel or culvert run with you or your maintenance staff. We look at drawdown, silt depth, embankment growth and outlet condition, then put together a scope that matches what the ground is actually doing, not a generic cleanout.
Most Bexar County properties need a full pass once or twice a year, with a closer look after any heavy rain event. New Stone Oak sites with bare slopes often need more attention in the first couple of years until vegetation establishes, while older Alamo Heights lots tend to need outlet and culvert checks more than regrading.
Yes, we plan around your property's traffic and schedule. For apartment and retail centers we coordinate mowing and debris work to avoid peak parking hours, and for HOA common areas we can route equipment to limit disruption to residents using paths or amenities near the channel.
Caliche soils and limestone shelves close to the surface mean swales here often hold water longer than the plan intended, because the ground will not absorb it. That slow drawdown lets silt settle in forebays and lets volunteer trees take root on embankments, which is exactly the kind of growth and blockage we clear.
Access and equipment needs drive most of the cost, along with how much silt and vegetation has built up since the last cleanout. A culvert that is fully blocked or an embankment with established trees takes more time than routine mowing and debris removal, and site layout affects how we move equipment in.
We handle both in the same visit when it makes sense. If grading, cleaning or culvert clearing turns up a bare or eroding slope, we address it as part of the scope, working to the property's existing plan rather than redesigning anything.
