HOT FLUID APPLIED ROOFING & WATERPROOFING SYSTEM
RamTough 250 is a thermoplastic, rubberized asphalt membrane that forms a completely monolithic waterproof system without seams or joints, adhering to horizontal and vertical surfaces. Melted on site, it is spread to a 90 mil thickness, reinforced with polyester scrim, and over coated with a 125 mil thick topcoat of RamTough 250 which fuses through the polyester to the bottom coat.
RamTough 250 sets instantly and remains flexible for the duration of its life. Not designed to perform as a permanently exposed surface, RamTough 250 should be protected: insulation, special coatings, cap sheets, and Barrett Greenroof-Roofscapes® are among the many options available.
