Polyurethane liquid membrane can be applied to any roof  be it a dome, butterfly, shed or hyperbolic paraboloid roof or a classic low sloped or flat roof. Be it a dome, butterfly, shed or hyperbolic paraboloid roof or a classic low sloped or flat roof, every roof structure has a unique character.Roofs are not just visual features; they fulfill the crucial role of protection. Being the highest point in a building, they take a battering from the elements and leaking is common after a few years. MARIS POLYMERS offers liquid-applied Polyurethane waterproofing systems with long-term protection for simple, detailed or complicated roof structures.
