Abstract:
A method for securing a cladding plate to a building substrate by means of an expandable material, such as a hydrophobic polyurethane foam, which is capable of expanding many times its original volume is disclosed. The hydrophobic polyurethane foam is introduced into a space between the cladding plate and the building substrate so as to create an adhesive bond between adjacent surfaces of the cladding plate and building substrate. The foam is introduced into the space either as a free flowing liquid dispensed into a retention basin created in the space or by means of a balloon from which it will expand freely upon fracturing of the balloon. The balloon is constructed so that it will break shortly after the material has turned into foam but before the material has lost its capability of adhering to the cladding plate and building substrate, and before the balloon pressure can overcome the retaining pressure delivered by the cladding plate and building substrate.
