Spray applied waterproofing membrane for tunnel concrete composite shell linings - MasterSeal 345

MasterSeal 345 is an EVA polymer based sprayable membrane for the waterproofing of underground concrete structures. MasterSeal 345 is spray applied in a sandwich structure between two sprayed concrete / cast concrete layers, creating a double bonded composite shell lining. MasterSeal 345 is flexible and has very high bond strength properties on both sides of the membrane. It is an effective alternative to conventional waterproofing sheet membranes. As a double bonded system, this provides excellent water tightness, preventing the development of water migration on both sides of the membrane. As with all spray applied membranes, it is not possible to seal against water ingress through the substrate. In such cases, a drainage system or local water management using drainage pipes should be used in combination with MasterSeal 345. However, it can be applied to damp substrate (as long as there is no running water). For more information, please contact your local Master Builders Solutions representative.
Cпецификация
  • MasterSeal 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.
