HYDROLASTIC PU-B is a water-based, cold-applied, single-component waterproofing membrane made from modified polyurethane dispersion extended with bitumen. It cures into a seamless, highly flexible monolithic membrane with excellent adhesion to concrete, plaster, masonry, bituminous felts, metal, and more. HYDROLASTIC PU-B is VOC-free, environmentally friendly, and odorless, making it ideal for both new construction and maintenance projects. It offers strong resistance to chloride and sulphate attacks, excellent corrosion protection, and high puncture and impact resistance. With easy paintable application, it withstands groundwater aggression and harsh site conditions. LEED eligibility further supports its sustainable and energy-efficient project contribution.
