Soft-dig service for St. Louis utility work.
St. Louis infrastructure runs deep and old. We hydrovac around live utilities, fiber conduit, and aging clay sewer systems across the metro — without the risk of mechanical damage from conventional digging. Our vacuum excavation trucks are right for tight urban corridors and active right-of-way jobs.
- Lambert Intl. Airport — utility daylighting
- HWY 55 corridor — fiber installation support
The full scope,
one contractor.
St. Louis is the metro hub we serve most — jobs span everything from downtown utility work to suburban site development across the 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.
St. Louis project work spans a spectrum that no other metro quite matches — century-old utility corridors downtown, suburban foundation digs through glacial till and clay, and commercial redevelopment in tight corridors where every buried line has to be confirmed before a bucket moves. Aging infrastructure in South City and North County generates steady sewer and water repair calls, and the utility density in the downtown commercial core makes hydrovac the standard for any excavation near established rights-of-way.
Our process
in St. Louis, 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 St. Louis, 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 St. Louis, MO, where infrastructure ages vary and utility maps aren't always current, soft-dig eliminates mechanical strike risk entirely.
Is emergency hydrovac service available in St. Louis, MO?
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 St. Louis, 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.
What size hydrovac jobs does J1S handle near St. Louis, MO?
Single pot-holes for utility verification up to full-day production hydrovac runs. If you're unsure whether your scope fits, call dispatch and describe the work — we'll confirm and give you an estimated timeframe.
