HYDROTHANE TR2 is a two-component, chemically cured, high-build liquid waterproofing membrane formulated from polyurethane resins extended with tar for enhanced elasticity and chemical resistance in demanding environments. Upon curing, HYDROTHANE TR2 forms a dense, seamless, monolithic membrane with superior adhesion to concrete, plaster, masonry, cement render, and fiber-reinforced substrates. The membrane is self-priming, vapor permeable to facilitate substrate breathing, and highly resistant to detergents, cleaning agents, brackish water, and saltwater. Its flexibility accommodates structural movements without risk of cracking, while offering high thermal stability suitable for Middle Eastern climates. Easy manual application and straightforward repairability ensure long-term, reliable waterproofing performance.
