Design and construction of permanent wood foundations

This WoodWorks webinar will provide guidance on the design and construction of permanent wood foundations (PWF) based on the Canadian standard CSA S406-16 – Specification of Permanent Wood Foundations for Housing and Small Buildings (external link). Topics will include site selection, backfilling, PWF floor systems, air and vapour barriers, insulation techniques, crawl spaces, and design considerations for high wind and seismic zones. The presentation will give attendees a comprehensive overview of the structural and building science requirements for designing and constructing PWF systems.

Learning outcomes:

• History of PWF construction
• Wood preservatives and material requirements for PWF
• Overview of pertinent design and construction aspects of PWF
• Standardization of PWF as per CSA S406
• Building science considerations for PWF systems
