Many types of building materials are needed to construct a house. Occasionally, one material can have a detrimental effect on an adjacent material resulting in premature material degradation. Builders, renovators and building designers need to be aware of this incompatibility issue and better understand how to determine if materials are compatible. Because there is no central registry for recording and sharing incompatibility problems, Canada Mortgage and Housing Corporation and the Canadian Home Builders' Association initiated this research project to help practitioners in the home construction industry to become and remain aware of material incompatibility situations.
