South Dakota city considers soil testing requirement for new residences
Soil testing is already required for commercial structures in Rapid City
May 15, 2015
The Rapid City, South Dakota City Council is considering a proposed building-code update that would require residential home builders to test soil conditions at each building site.
The problem: Expansive soils alternately shrink and swell during dry and wet spells, shifting homes and causing heaving floors and ruptured walls. Soil testing is already required for commercial structures in Rapid City.
