Repair and stabilization of eroded pond slopes, embankments and channels using grading, soil stabilization, vegetation or riprap.
Detention pond erosion repair in Marble Falls deals with a problem specific to this part of the Hill Country: pink granite outcrops shed grit fast, and once a slope or channel loses its grass cover, that decomposed granite moves downhill with almost every rain event. A pond built to hold water during a storm does no good if its embankment is cutting new channels or its outlet is buried under sediment that washed off bare rock upslope.
Around Gregg Ranch, Meadowlakes and Horseshoe Bay, the pattern shows up the same way season after season. A forebay that was two feet deep at construction is silted in to six inches. Side slopes that were seeded once and never mowed grow volunteer cedar and mesquite, whose roots work into the embankment and loosen soil for the next heavy rain. Outlet structures clog with granite fines and leaf litter, drawdown slows from a day to a week, and the next storm has nowhere to go but over the top of a slope that was never meant to carry flow.
Working with Corral Bros on this scope starts with a site walk, not a guess. We look at the slopes, the channel, the outlet, and we tell a property manager or board plainly what has failed and what is just due for maintenance. Regrading, stabilization, riprap or matting and re-vegetation get scoped to the plan or alongside your property engineer, and the work gets done with tenants, residents and parking in mind, not around them.
We're a local, family-built company that treats your Marble Falls property like our own, tidy crews, clear pricing, and detention pond erosion repair that holds up to Burnet County conditions. Available as a one-time project or part of an ongoing plan.
We walk the basin with whoever is responsible for it, usually a property manager or a board member, and look at the embankment, the forebay, the outlet structure and any channel feeding or leaving the pond. Estimates are free and no-obligation, and we usually get out within 48 hours of your call. You will get a clear scope before anything is scheduled, including which slopes need regrading and where riprap or matting makes sense.
It depends on the age of the development and how much granite grit is washing in, but most Highland Lakes basins need some slope or channel attention every few years, sooner if a storm has cut a new rill or an outlet has gone slow. Boards often notice it first as standing water that will not draw down or a forebay that has filled in faster than expected.
Yes, we schedule around tenant traffic and parking needs and coordinate access with the property manager ahead of time. Most embankment and channel work stays within the drainage easement, away from building entrances and parking rows, so day-to-day operations continue normally while crews regrade slopes or place riprap.
Pink granite grit sheds fast off exposed rock and bare slopes, and it tends to settle hard in forebays and low spots rather than filtering through, so channels silt in and outlets can choke faster than in black-clay soil. Stabilization work here often leans on riprap and erosion matting over straight seeding, since bare granite soil is slow to hold new growth on its own.
The main drivers are how much slope and channel length needs regrading, how far soil or rock material has to be moved on site, and whether the outfall structure itself needs rebuilding or just clearing. Access also matters. A pond tucked behind a Gregg Ranch retail center with tight equipment access costs differently than an open embankment on a ranch-style property.
