Residential foundation systems for permafrost regions / submitted to Canada Mortgage and Housing Corporation ; submitted by AGRA Earth & Environmental Limited. : NH21-8/2000E-PDF

"Permafrost underlies all of the Yukon, Northwest and Nunavut Territories and much of the northern portions of the provinces, especially Manitoba and Quebec. Frozen ground conditions can have significant adverse effects on structures in the north. The effects of settlement and frost heaving commonly result in the premature deterioration of residential structures. Problems related to foundation design and construction can be reduced to a minimum if care is taken in the selection of suitable sites and appropriate foundation systems. This report presents the results of a literature review, interviews and onsite visits to assess feasible foundation systems for residential construction in permafrost regions. The type of foundation system depends on a number of factors, including type and characteristics of the permafrost, subsurface conditions, availability of excavation equipment, availability of skilled labour, and others"--Exec.
