Detail waterproofing is important for the protection of the roof  in roof structure.Complex and tricky details are some of the classic weak points in roof structures. Wall-floor connections, Flashings and 90o angles, Lightdomes, Rooflights, Chimneys, Pipes, Siphons and Gutters are normally causing most problems in roof waterproofing. MARIS POLYMERS offers the MARISEAL® DETAIL, a liquid Polyurethane detail waterproofing system with long-term protection for simple, detailed or complicated roof detail structures.
