Hydrovac service in Oakville and South St. Louis County.
Oakville sits near the Jefferson County line — we run hydrovac jobs through here regularly. Dense residential development means utilities are close together, making hydrovac the right call for any utility-adjacent dig.
The full scope,
one contractor.
Oakville is a well-established south St. Louis County suburb — a mix of residential renovation work and new builds along the south county corridor, close to the Jefferson County line. We don't sub the work out — the same crew that quotes the job does the work.
Pressurized water cuts soil without touching what's buried — no mechanical damage risk to gas, electric, fiber, or water lines.
The hose reaches where heavy equipment can't. Dense corridors, active facilities, and residential lots are all workable.
We expose sewer and water lines safely for camera inspection, repair access, and tie-in verification before any mechanical work begins.
Utility strikes and active breaks don't wait for business hours. Dispatch is available around the clock for emergency hydrovac response.
Approved for Metropolitan St. Louis Sewer District work — required for insurance-covered sewer repairs throughout the service area.
Our operators hold NULCA certification — the industry standard for safe vacuum excavation around buried utilities.
Local conditions,
local expertise.
Oakville is a mature St. Louis County suburb with well-established residential neighborhoods and commercial corridors along Lindbergh and Telegraph. The housing stock runs heavily 1960s through 1990s — an age range where sewer laterals and water service lines fail with increasing frequency. The terrain here is gentler than Jefferson County, with fewer rock surprises and more clay-dominant soil, making most excavation and utility work relatively predictable. The density of development leaves little margin for error on any dig adjacent to existing structures or active utilities.
Our process
in Oakville, MO.
Before the truck moves, we confirm all utility locates are in. We call 811 and coordinate on any private locates not covered by the state ticket — irrigation, private fiber, or unmarked service lines.
The hydrovac unit is positioned for hose reach to your dig area. Water pressure is set to match soil conditions — more for compacted clay and fill, less for loose or sandy ground near buried utilities.
Pressurized water cuts the soil column. The vacuum pulls material into the debris tank continuously. No steel near your utilities — the process eliminates mechanical strike risk entirely.
Material goes into the tank and off your site. We backfill or leave the opening per your downstream repair or inspection scope. The area is left clean and documented with photos.
Hydroexcavation
in Oakville, MO
What is hydroexcavation and how does it differ from conventional digging?
Hydroexcavation uses pressurized water to break up soil and a vacuum to extract the debris — no steel tools near your utilities. Conventional excavation uses a bucket or blade, which can strike and damage buried lines. In Oakville, MO, where infrastructure ages vary and utility maps aren't always current, soft-dig eliminates mechanical strike risk entirely.

Yes. We run 24-hour emergency dispatch for utility strikes, active breaks, and time-sensitive daylighting jobs. Call (636) 465-4226 for emergency response in Oakville, MO and the surrounding area.
Do utilities need to be located before you arrive?
Yes — a valid 811 locate ticket is required before any vacuum excavation begins. For private utilities not covered by 811 (irrigation systems, private fiber, unmarked service lines), arrange private locates in advance. We'll walk the site with you before work begins.
