Waterproofing for the water management industry includes protecting areas with high chemical and mechanical demands (inflow) and those where potable water is stored (disinfection and outflow). MasterSeal M 808 is a multi-purpose waterproofing membrane designed to deliver long-term protection in demanding environments by reducing the risk of ingress by water and water-based solutions containing chemicals.

This waterproofing membrane for the water industry is equally at home in industrial process situations where concrete or steel structures are affected by water containing aggressive chemicals. A two-component polyurethane membrane, it offers high elasticity to bridge substrate cracks, as well as high chemical resistance. Once applied, this monolithic membrane to bonds fully to the substrate, with no laps, welds 

MasterSeal M 808 is suitable for both concrete and metallic substrates. Long-term durability is this membrane's standout feature: high chemical resistance, low permeability to water and high elasticity ensure the membrane's integrity, even on moving substrates with opening cracks. Its long pot life allows application by roller or airless spraying.

MasterSeal M 808 has high abrasion and impact resistance, ensuring the membrane's long-term stability when exposed to mechanical loads. Its properties and system design enhance the waterproofed substrate's durability.

MasterSeal M 808 fulfils local and European legislation requirements for direct contact with potable water, including regulations on lists of constituents and migration tests. It has approvals from several European countries for contact with potable water, while full certification according to EN 1504 part 2 ensures consistent performance.
