Permafrost Foundations

Permafrost Foundations CCHRC worked with the U.S. Army Cold Regions Research and Engineering Laboratory (CRREL) to study ways of pairing information on permafrost soils with optimal foundation designs. The current method of building on permafrost is to drill a series of intermittent holes in the ground on a given site to search for permafrost, a…

Anchorage Foundation Insulation Study

Builders in Southcentral Alaska asked CCHRC to study an insulation strategy currently being recommended that involves insulating with R-38 batts from the rim joist down the foundation wall and four feet horizontally inward along the crawlspace floor. Through monitoring temperatures in and around foundations, CCHRC is investigating whether the technique may subject foundations to frost…
