Preserved wood foundations (PWF) are gaining increased acceptance by builders and home owners in certain areas of Canada. The use of masonry veneer as an exterior cladding, alone or in combination with wood, hardboard or aluminum siding is in common use in many municipalities across the country. The technique of supporting masonry veneer on wood foundation is completely new, however, and a performance history based on traditional practise has not been developed. Consequently, building codes have not defined minimum standards of construction for this building system. This field study was initiated and partially supported by the Canadian Wood Council through its Wood Foundation Committee to identify wood foundation houses that utilize masonry veneer cladding and to observe how the cladding was performing in service. Information was obtained on the construction details of the supporting walls and other specialized features of the structure. Notes were taken, wherever possible, on the type of drainage employed.
