MASTERSEAL® 940

• Complete range of profiles and sizes to suit all construction requirements.
• Reinforced eyeleted fixing flanges on internally placed profiles for positive location in joints prevents collapse of profile during concrete placing.
• Four valve sealing system on all profiles.
• Premoulded intersection/ junction pieces available.
•  

• Provide a complete sealing network for expansion and contraction / construction joints in water retaining and water excluding in-situ concrete structures.
• Prevents the passage of water through expansion / contraction / construction joints in the following typical structures: Canals / culverts, Water tanks, Reservoirs, Dams, Sewerage Treatment Plants, Liquid retaining vessels and all cast in-situ concrete structures to retain or exclude water.
•  

The choice of width of profile is mainly governed by slad/wall thickness, position of reinforcing steel and aggregate size. As a general rule, the 250 mm width profiles are appropriate for slab/wall thickness over 250 mm, allowing good compaction and width of barrier to water penetration.
