South Dakota

Serving The Mount Rushmore State since 1992

South Dakota’s harsh winters, expansive clay soils, and seasonal moisture fluctuations make homes across the state especially vulnerable to foundation settlement, basement water intrusion, and crawl space deterioration. The region’s frequent freeze-thaw cycles and shifting soil conditions also lead to cracked, sinking concrete around residential properties. Innovative Basement Authority and Groundworks proudly serve South Dakota homeowners with expert solutions in foundation repair, basement waterproofing, crawl space encapsulation and repair, and concrete lifting and leveling. Backed by BBB A+ accreditation and a team of certified field inspectors offering free, no-obligation inspections, we deliver long-lasting, customized repairs built to withstand South Dakota’s challenging climate and terrain. From Sioux Falls to Rapid City, we’re here to protect your home from the ground up.
