Jefferson County Excavation, hydroexcavation, hauling & site work — from the contractor based right here.

Jefferson County terrain changes significantly from north to south. The Arnold corridor and northern townships carry clay-dominant soils with occasional rock. Moving south toward Hillsboro and De Soto, limestone bedrock becomes shallower and rock excavation work increases. The Mississippi River corridor adds flood plain considerations for below-grade work near Crystal City, Herculaneum, and Festus. County-wide, aging sewer laterals in older neighborhoods are consistently at or past end-of-life — a steady source of repair and replacement work across the service area.
