Excavation contractors in Benton County, TN

This western lowland and bluff corridor features two distinct ground profiles: the deep alluvial silt and clay floodplains of the Mississippi River basin and the massive, wind-deposited loess bluffs flanking the river. Loess soils (Memphis series) possess unique cohesion that allows deep, near-vertical trench walls when bone dry, but they disintegrate into a fluid, highly erodible slurry upon water contact. Gully erosion along cut slopes can develop within hours of heavy rainfall unless protected with hydroseeding and erosion control blankets. In the lower alluvial plains, deep stone-free clays and silts feature high water tables and poor load-bearing capacity, requiring extensive geotextile fabric, crushed aggregate sub-base, and continuous dewatering pumps for deep utility trenching.
