uncompromising, tough, flexible membrane that delivers design
flexibility, durability and proven performance.
250 is composed of SBS rubber polymers and specially refined
unoxidized asphalt with a mineral filler and recycled tire rubber.
This thermoplastic rubberized asphalt membrane forms a completely
monolithic waterproofing system without seams and joints. The
ram-Tough 250 is heated in an agitated melter on the jobsite
and spread onto the deck and walls. It is reinforced with spunbond
polyester and neoprene flashing creating a 215 mil think protective
waterproof membrane. The rubber material's weblike molecular
structure creates a microscopic elastic network of strong rubberized
strands. During the polymerization process, the network absorbs
the bitumen to produce a waterproofing material with exceptional
self-healing properties, excellent toughness, tenacity, elongation,
fatigue resistance and cold termperature flexibility.
