Removal of water, sediment, sludge, trash and debris from underground detention vaults and the stormwater components tied to them.
Granite and limestone sit close to the surface through most of Spicewood, which means rain does not soak in so much as it runs. That runoff moves fast off the rock and picks up grit on the way down, and underground detention vaults serving Barton Creek Lakeside, Spicewood Trails and Briarcliff take the brunt of it. Corral Bros handles underground detention vault cleaning for the boards, managers and owners who are responsible for keeping those systems working.
On thin Hill Country soil, sediment does not settle out gradually the way it does on flatter clay sites. It arrives in a rush during heavy runoff and drops hard in the forebay, which is usually the first place we find a problem. We also see slow drawdown after storms, outlet structures packed with grit and leaf debris, and volunteer trees taking root on embankments where ranch and lake properties back up to open acreage. Underground, the same sediment load works its way into connected pipes and chambers, narrowing flow before anyone notices from the surface.
Working with us starts with a site walk, not a sales pitch. We open the vault, check sediment depth and water, and tell you what we see before we talk about scope. From there we dewater the vault, pull sediment, sludge, trash and debris, and clean the pipes and chambers tied into it, following confined-space safe practices the whole way through. You get a crew that has done this work on Hill Country ground before and knows what granite runoff leaves behind.
We're a local, family-built company that treats your Spicewood property like our own, tidy crews, clear pricing, and underground detention vault cleaning that holds up to Burnet County conditions. Available as a one-time project or part of an ongoing plan.
We schedule a free on-site walk, usually within 48 hours of your call, and open the vault to check sediment depth, standing water and the condition of the outlet structure. On rock lot sites like Barton Creek Lakeside or Briarcliff, we also check access, since some vaults sit along narrow private drives with limited truck turnaround. You get a straight answer on scope before anything is scheduled.
Most vaults tied to ranch or lake developments here need a full cleanout every few years, but a heavy runoff season off the granite slopes around Spicewood Trails can silt a forebay faster than that. Watch for slow drawdown after storms or water sitting in the vault days after rain stops. Those are signs sediment has built up past what routine inspection can fix.
We coordinate access windows with property management or the HOA board ahead of time, since most vaults sit under parking areas, access roads or common space. Work is staged to limit how long any drive or lot section is blocked. For retail centers and apartment communities, we schedule around peak traffic hours when the board or manager asks us to.
Thin soil over granite and limestone means runoff moves fast and carries grit straight into the vault instead of filtering through deeper soil first. That shows up as a silted forebay, a sluggish outlet, or sediment packed into connected pipes faster than you would see on flatter, deeper-soil sites. Remote acreage properties also tend to collect more wind-blown debris and leaf litter between service visits.
Sediment volume is the biggest factor, followed by how much standing water needs to be pumped down before we can work. Confined-space access, pipe and chamber condition tied to the vault, and site access on Hill Country lots with limited truck room all factor in too. We price it after the site walk, not before, so the number reflects the actual vault.
