ABSTRACT:
A method is presented for extending the lives of existing slate, fibrous cement and clay tile roofs. The method involves injecting an especially formulated, polymer material into the spaces and voids of adjoining tiles. The injection process uses pumping equipment with a custom-designed gasket at the spray gun's point of application to aid in directing the grout into the spaces and voids.
