Cleaning, mowing, grading, vegetation control, debris removal and erosion repair for drainage swales, channels, ditches and culverts.
Swale, channel and culvert maintenance in Schertz is a standing item on the job list, not a one-time fix, because the drainage built into communities like The Crossvine, Ashley Park and Forest Ridge was designed around assumptions that the ground does not always keep. Fast-growing sections along I-35 and FM 78 came out of the ground on tight construction schedules, and the swales and channels that move water off those sites need regular attention to keep performing the way the plans intended.
The blackland clay under most of Schertz swells when it is soaked and shrinks hard when it dries, and that movement shows up in the drainage system before it shows up anywhere else. A swale that graded out fine at handover can go flat or even reverse pitch in a spot after a couple of seasons. Forebays silt in faster than owners expect after a hard rain, culvert mouths catch leaves and construction debris left over from nearby phases still being built out, and bare slopes on newer embankments erode or sprout volunteer trees whose roots work against the bank instead of holding it.
Working with Corral Bros on this scope means a crew that walks the actual swales, channels and culverts on your property, not just the pond itself, and tells you plainly what is clogged, what is eroding and what is still doing its job. We clean and mow, clear culverts and ditches, regrade where the slope has drifted, and repair erosion, on engineered sites working to the grading your property engineer specified. You get a straight scope and a free on-site estimate, usually within 48 hours of calling (737) 404-9343.
We're a local, family-built company that treats your Schertz property like our own, tidy crews, clear pricing, and swale, channel & culvert maintenance that holds up to Guadalupe County conditions. Available as a one-time project or part of an ongoing plan.
We walk the full drainage path with you, swales, channels, culvert inlets and outlets, and note where water is slow to clear or where silt and vegetation have built up. You get a free, no-obligation estimate, usually scheduled within 48 hours of your call, with the scope broken out by area so a board or ownership group can see exactly what is being done and where.
Most master-planned sections here need a mowing and inspection pass every few weeks in the growing season and a closer look at culverts and channel bottoms once or twice a year. New sections tend to need it sooner than older ones because grading is still settling and turf has not fully established on the slopes.
We schedule channel and swale work around normal traffic patterns and give notice when equipment will be staged near a parking area, access road or shared drive. Crews work section by section rather than shutting down an entire corridor at once, so most of the property stays accessible while we move through the system.
This clay swells when it is wet and shrinks and cracks when it dries out, which shifts grading over time and can leave a swale holding water longer than it should. It also sheds fine silt fast in a hard rain, which settles in channel bottoms and culvert openings and slows drawdown until it is cleared out.
Length and number of swales and culverts, how much silt and vegetation has built up, slope erosion severity, and access all factor in. A system that has gone a season or two without attention costs more to bring back than one on a regular maintenance cycle, and sites with tight access or heavy tree growth on embankments take longer to clear.
Both. Beyond cleaning out culverts and clearing vegetation, we reshape and regrade swales and channels that have lost their original slope and repair eroded banks so water moves the way it was designed to. On engineered sites we work to the grading shown on the property's plans rather than guessing at slope.
