RamTough 250 is Hot Rubberized Asphalt Roofing & Waterproofing Membrane Waterproofing System that is uncompromising, tough, durable, and offers peace of mind to the owner with a single, seamless system. Fully adhered and monolithic, it leaves no seams or joints for water to find.
RamTough 250 is an uncompromising, tough, flexible membrane that delivers workability, durability, and peace of mind to the owner with a single, seamless system. Fully adhered and monolithic, it leaves no seams or joints for water to find.
The membrane is composed of SBS rubber polymers, specially refined unoxidized asphalt, mineral filler, and recycled tire rubber — a 100% solids formulation with no solvents, urethanes, or other additives.
Using a double-jacketed, hot-air, or oil-bath melter, RamTough 250 is heated on the jobsite to a fluid state and squeegeed onto the deck and walls, building a minimum 215-mil-thick waterproofing membrane reinforced with spunbond polyester.
Using a double-jacketed, hot air, or oil bath melter, RamTough 250 is heated on the jobsite to a fluid state and spread onto the deck& walls. It is reinforced with spunbond polyester and neoprene flashing, creating a minimum 215 mil thick protective waterproof membrane.
Barrett’s RamTough 250 creates a seamless, fully adhered waterproofing membrane with no joints or weak points. Applied hot, it forms a continuous barrier for unmatched protection on horizontal and vertical surfaces in demanding roofing and waterproofing applications.
The material’s web-like molecular structure creates a microscopic elastic network of strong, rubberized strands. During the polymerization process, the rubber network absorbs the bitumen to produce a rubber-like waterproofing material with exceptional self-healing properties, excellent toughness, tenacity, fatigue resistance, and flexibility, especially at cold temperatures.
RamTough 250 is composed of SBS rubber polymers, specially refined unoxidized asphalt, mineral filler and recycled tire rubber. This 100% solids thermoplastic rubberized asphalt membrane forms a completely monolithic waterproofing system without seams and joints.
