Radon Mitigation in Anchorage, AK

Radon Mitigation in Anchorage: local conditions

Anchorage, AK sits on silt and permafrost-affected soils and has a cold subarctic climate with about 16–30" of precipitation a year. The local water table is variable, with permafrost and deep seasonal frost, with extreme, deep winter freeze–thaw and frost heave, and many homes have basements or heated crawl spaces for frost protection. In practical terms, deep frost, permafrost and frost heave are the dominant foundation threats — which is exactly why radon mitigation is a common need here.
