    Sika Waterbar®-940 (formerly known as MasterSeal® 940) - Internally and externally placed PVC Waterstops

    How does MasterSeal 940 work?

    MasterSeal 940 is a range of internally placed and externally placed PVC Waterstops extruded from high grade PVC compound.

    What is MasterSeal 940 used for?

    MasterSeal 940 is designed to provide a complete sealing network for expansion and contraction/ construction joints in water retaining and water excluding in-situ concrete structures. The profiles are supplied in straight lengths to be butt jointed on site.

    The use of MasterSeal 940 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
    • All cast in-situ concrete structures to retain or exclude water

    What are the benefits of MasterSeal 940?

    Among the numerous advantages of MasterSeal 940 we can find the following:

    • Complete range of profiles and sizes to suit all construction requirements.
    • Reinforced eyeleted fixing flanges on centrally placed profiles for positive location in joints prevents collapse of profile during concrete placing.
    • Simple on-site butt welding.
    • Four valve sealing system on all profiles.
