PU Waterproofing (Polyurethane Waterproofing) is a high-performance liquid-applied waterproofing system that forms an elastic, seamless, and durable membrane over various substrates. It is ideal for roofs, terraces, balconies, and podium slabs where long-term flexibility and UV resistance are essential. The polyurethane coating penetrates and bonds firmly to concrete and masonry surfaces, providing outstanding resistance against water ingress, thermal expansion, and harsh weather conditions. Its seamless finish eliminates joints and weak points, ensuring a long-lasting, watertight barrier suitable for both new construction and repair applications.
