St. Charles County, MO

Wentzville is one of the busiest building areas in the region, and every new pad, road widening and subdivision street means digging near lines that are already in the ground. Our hydrovac trucks run out of O'Fallon, a short trip up I-70, to pothole and daylight those utilities so crews can see them before excavation starts.

## Local conditions in Wentzville

Industrial and commercial work along I-70, the I-64 interchange and the Highway A corridor often crosses gas, fiber, electric and water lines in tight spaces. After Missouri 811 marks the area, hydrovac potholing exposes each line so you can confirm its exact position and depth instead of relying on paint alone.

New subdivisions off Wentzville Parkway and Highway Z bring their own needs: tying into existing mains, setting utilities near recently installed lines, and slot trenching where a backhoe would be risky. Water loosens the soil, a vacuum lifts it into the truck's tank, and the line underneath is left exposed.

Wentzville's clay soil digs slower than sandy ground, and that affects how many potholes a crew can finish in a day. We factor soil into the written quote, and our hydrovac estimator gives you a range to plan with before you call.

Yes. We pothole, daylight and slot trench for contractors on road, utility, commercial and residential development work around Wentzville.
