Radon Mitigation in Duluth, MN

Radon Mitigation in Duluth: local conditions

Duluth, MN sits on glacial clay and silt and has a cold continental climate with about 30–34" of precipitation a year. The local water table is variable, with many lakes and high spots, with severe, deep winter freeze–thaw cycling, and full basements are standard for frost protection. In practical terms, deep frost and freeze–thaw make frost heave and wall cracking a leading concern — which is exactly why radon mitigation is a common need here.
