MasterRoc MSL 345

Waterproofing Membrane
What is the purpose of MasterRoc MSL 345?

MasterRoc MSL 345 is a sprayable membrane for waterproofing concrete structures. MasterRoc MSL 345 membrane is spray applied between layers of sprayed or cast-in-place concrete. 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

Recommended uses:

  • Cast-in-place

  • Composite-designed shotcrete sandwich structures (concrete or shotcrete/membrane/ concrete or shotcrete)

  • Underground structures with complex profiles and geometry

  • Bonds to steel and most sheet membranes enabling interface solutions with other waterproofing methods

What are the unique features of MasterRoc MSL 345?
  • Dry-process material, ready-for-use

  • Elasticity 80-140% (depending on the temperature)

  • Fast curing

  • No toxic components

  • Environmentally preferable

What are the benefits of MasterRoc MSL 345?
  • Easily applied by spraying with standard dry-process shotcrete equipment

  • Two-sided bond with sprayed-concrete allows for composite behavior

  • Fast curing prevents disruption of construction operations

  • The fully bonded system provides excellent watertightness, preventing development of water migration in both concrete membrane interfaces
