Duram Azcothane REO: High-Performance Fibre-Reinforced Waterproofing Membrane
Advanced Protection for Demanding Construction Applications
Duram Azcothane REO represents the pinnacle of liquid-applied waterproofing technology. This innovative membrane is a water-based, polyurethane-fortified acrylic hybrid, uniquely reinforced with integrated microfibres. This internal reinforcement is a game-changer, eliminating the traditional need for external fibreglass or polyester matting. The result is a streamlined application process that is significantly quicker and easier, reducing labour costs and potential for error. Formulated to meet the rigorous criteria of AS4858:2004 for Wet Area Membranes and successfully tested to AS 4654.1, Azcothane REO provides a certified, reliable solution that complies with the National Construction Code of Australia (NCC), giving architects, builders, and contractors absolute peace of mind.
Unmatched Features and Key Benefits for Professionals
Azcothane REO is packed with features designed for performance and on-site efficiency. Its single-pack, no-mix formula with anti-sag technology ensures consistent application on both horizontal and vertical surfaces. Being water-based, it allows for easy clean-up with water, minimising the need for harsh solvents and improving workplace safety. The membrane cures to form a seamless, fully bonded, and highly flexible layer that can withstand structural movement with an elongation at break of over 300%. Furthermore, it is bitumen and tar-free, preventing unsightly stains on tiles and grout, and has been formulated to inhibit biological growth. With low VOC levels meeting Green Star criteria, it is an environmentally conscious choice for modern construction projects.
Ideal Applications and Suitable Surfaces
This versatile membrane is engineered for a wide range of protected waterproofing applications above grade. It is the ideal choice for balconies, terraces, decks, and podiums where long-term, watertight integrity is critical. In internal wet areas, it provides a robust solution for shower recesses, bathrooms, and laundry areas. It is also perfectly suited for detailing complex areas like window reveals. Azcothane REO can be applied to a variety of clean, sound, and dry substrates, including concrete, cementitious screeds, masonry, and lightweight composite sheeting. Its compatibility with direct stick tile and render applications (once fully cured) further simplifies the construction process.
Trusted Quality and Important Considerations
As an Australian-made product from Tremco CPG, a global leader in construction solutions, Azcothane REO is backed by extensive local experience and technical support. It is supplied in a convenient 15-litre pail, with a standard coverage of approximately 15m² per pail for a two-coat waterproofing system at a total thickness of 1.0mm. It is crucial to note the product's limitations to ensure optimal performance: it is not suitable for direct contact with high concentrations of chlorine, application on wet substrates, use as a trafficable surface, or for below-grade applications like planter boxes. For project-specific advice and substrate preparation guidelines, consulting with Tremco CPG is always recommended.
