Aquaflex WPU Hybrid PU Membrane

Aquaflex WPU is a high-performance, water-based hybrid polyurethane waterproofing membrane engineered for internal wet areas and external exposed applications. Formulated with advanced PU dispersion technology, it delivers excellent flexibility, crack-bridging performance, and long-term durability across concrete, screed, render, and masonry substrates.

Certified as a Class III membrane to AS 4858 and compliant with AS 3740 and AS 4654.1, Aquaflex WPU is suitable for bathrooms, balconies, podium decks, and roof areas where movement tolerance and UV resistance are critical. With elongation exceeding 300%, it accommodates structural movement while maintaining a continuous, seamless waterproof barrier.

Aquaflex WPU dries to a durable light grey finish and can be tiled over or left exposed where specified. It offers strong adhesion, low VOC content, and is suitable for both residential and commercial waterproofing systems requiring compliance and constructability.
