2: Masonry and Wood Protection and Repair

This chapter deals with the susceptibilities of materials other than concrete used in the building and construction of masonry walls, and how polymers can be used to provide protection and for remediation where problems develop. It also includes wood and wood-based products used in the construction of buildings, and for timber and plywood that is permanently in contact or exposed to wetting with ground, fresh and salt water. The major industrial applications for which the essential chemistry and technology of polymers used, and the fitness-for-purpose test methods considered, are: Invisible penetrating cladding and protective membrane cladding for masonry walls which redirect waters or wind and controls run-off to prevent infiltration of weather elements; Cold liquid applied roofing membrane coatings which fully bond to traditional roofing materials and form a monolithic encapsulating waterproofing and weathering protection membrane even round complex contours; Resinous and polymeric waterproofing and fouling protection for wood in continuous contact with salt water and marine biofouling organisms, and barrier protection for wood in fresh, ground and brackish water contact.
