MasterRoc MSL 345 membrane is a sprayable membrane for waterproofing concrete structures and water management. MasterRoc MSL 345 membrane is spray-applied between layers of sprayed or cast-in-place concrete or as a stand-alone membrane. MasterRoc MSL 345 membrane exhibits high bond strength to the substrates on both sides of the membrane with good elasticity.
MasterRoc MSL 345 membrane can be directly applied to damp sections of substrate.
MasterRoc MSL 345 is suitable for all types of tunnel designs and is particularly well suited for underground structures with complex profiles and geometry such as stations, escape and access tunnels, utility caverns, cross passages and tunnel intersections. Enables tunnel design with composite shell lining to reduce excavation cross section and lining thickness, and is especially suited to tunnel rehabilitations.
