Bitumen Modified PU Liquid Membrane
Developed for water-exposed building areas such as foundations, terraces, roofs and wet areas, this two-component (2K), fast-curing, seamless waterproofing membrane delivers lasting protection even at the most demanding details.
What Is Bitumen Modified PU Liquid Membrane?
Polyurethane (PU) based liquid membranes are applied in liquid form, unlike traditional bituminous sheets, and cure into a seamless, fully-bonded single-layer waterproofing coat. Bitumen modification adds extra flexibility, weather resistance and a cost-effective advantage. Thanks to these properties, the product is reliably used on foundation retaining walls, terraces and balconies, roof details, wet floor applications and demanding joint/corner details.
