TRUBUILD TRU PU is a single-component, water-based, bitumen-modified polyurethane waterproofing membrane designed to create a seamless, highly flexible, liquid-applied waterproof barrier for concrete and masonry structures. Once cured, it forms a continuous membrane that protects surfaces against seepage, water ingress, moisture damage, and weather-related deterioration.

The product is engineered for projects where easy application, long-term flexibility, and dependable waterproofing performance are critical. Being a ready-to-use single-component system, it eliminates site mixing complexity and allows faster execution using standard brush or roller application methods. Its elastomeric behavior helps accommodate minor structural movement and offers crack-bridging capability up to 2 mm, helping maintain waterproof integrity over time.

TRU PU also provides excellent adhesion across multiple substrates, strong resistance to oxidation and brittleness, and maintains elasticity across varying temperatures. This makes it suitable for both exposed and protected waterproofing applications where durability and reduced maintenance are important.
