Removal of water, sediment, sludge, trash and debris from underground detention vaults and the stormwater components tied to them.
Comal County sits where Hill Country caliche and limestone edge give way to river sand, and that split personality shows up fast in an underground vault. One side of New Braunfels drains gravel and rock fines that settle out quick and hard. The other, closer to the Guadalupe and Comal rivers, washes in fine sand that moves through a system until it finds a low spot and stays there.
In riverfront neighborhoods and Gruene-area lots, that sand loads into the vault floor and the first chamber off the inlet, slowing drawdown until a normal rain leaves standing water for days. Out toward Vintage Oaks and River Chase, newer construction means exposed slopes and fresh cut grades, so silt fences fail, bare soil washes in, and a vault that was clean at final inspection is carrying sediment within a year or two. Older sites get volunteer trees working into joints and risers, and outlet structures that choke on leaves and construction debris left over from buildout.
We show up, open the vault, and tell you what is actually down there before anyone touches a shovel. Dewatering, sediment and sludge removal, trash cleanout, and the connected pipe and chamber runs all get handled under confined-space safe practices, working to your engineer's plan where one applies. For a board or a property manager, that means one call, a scheduled visit, and a vault that drains the way it was designed to.
We're a local, family-built company that treats your New Braunfels property like our own, tidy crews, clear pricing, and underground detention vault cleaning that holds up to Comal County conditions. Available as a one-time project or part of an ongoing plan.
We walk the vault and the connected stormwater run with you or your engineer, note sediment depth, standing water, and any structural or access issues, then give you a free no-obligation estimate. Most sites get scheduled for that walk within 48 hours of your call, which matters when a board is trying to close out a budget cycle or a GC is waiting on turnover.
It depends on what is upstream, but a lot of New Braunfels vaults need attention every two to three years, sooner on newer Vintage Oaks or River Chase sites still shedding construction sediment. Watch for slow drawdown after a normal rain, standing water that lingers past a couple of days, or a forebay that looks shallower than it used to.
Yes. Most vault access points sit in drive aisles, landscape islands, or parking rows, so we schedule around peak tenant or resident hours and coordinate with your management office on which spaces need to be roped off. For apartment and retail sites we keep the footprint as small as the access point allows.
Riverfront sites near Gruene and the river corridors tend to load fine river sand into the vault floor and first chamber, while rockier Hill Country edge lots shed coarser sediment that settles fast near the inlet. Either way, drawdown slows before anyone notices a problem on the surface, which is why we check the outlet structure and connected pipe runs every visit, not just the main chamber.
Sediment volume and whether it has hardened into sludge versus loose fines, how much trash and debris has collected at the outlet, how many connected chambers and pipe runs need cleaning, and how accessible the vault is for equipment all factor in. A vault that has gone five years without attention costs more to clear than one on a normal two-year cycle.
