2 Concrete Leveling Contractors in Otsego, Minnesota

If you need concrete leveling in Otsego, the usual culprits are low-cohesion Anoka Sand Plain outwash washing out under slab edges, Mississippi River terrace groundwater cycling, new-construction fill consolidating under subdivision driveways, and deep seasonal frost. Otsego is a growing city in southeastern Wright County, Minnesota, along the Mississippi River and MN-101 on the northwest edge of the Twin Cities metro. The area sits on the Anoka Sand Plain, a flat sandy lake plain and series of terraces along the Mississippi River. The subsection was formed by glacial outwash of the Grantsburg sublobe of the Des Moines Lobe, and recent mapping suggests much of the sand plain, once thought to be fluvial, is probably lacustrine in origin. The major landform is a broad sandy lake plain containing small dunes, kettle lakes, and tunnel valleys, with level to gently rolling topography. Surface glacial deposits here are usually less than 200 feet thick, and the subsection is underlain by Cambrian and Ordovician dolomite, sandstone, and shale. Soils are derived primarily from the fine sands of the sandy plain. Meltwater drained around the outer northeast margin of the Grantsburg ice lobe, reworking the former lake bed and forming the Anoka Sand Plain across this stretch of the Mississippi corridor. Local soils include Hubbard loamy sand and Zimmerman fine sand on the sand-plain uplands, Anoka loamy sand on the minor terrace flats, sandy alluvium along the Mississippi River corridor, and organic muck in the kettle wetlands. Between the low-cohesion outwash subgrade, the Mississippi terrace water table, and the shallow bedrock below, subgrade behavior is the primary driver of slab movement here.
