• Newton 403 Hydrobond®

    Externally Applied Waterproofing Membrane And Gas Barrier Variant

    High performance composite sheet membrane that features a locking fleece to one side and a polymer hydrophilic coating to the other, as well as gas barrier capabilities.

    Key Benefits

    • Agrément certified and NHBC accepted waterproofing system
    • Forms a full mechanical bond to concrete to prevent water migration between the membrane and the structure
    • Good abrasion and very high resistance to freeze/thaw cycles and de-icing saltsThe hydrophilic layer provides self-healing capabilities when the membrane is punctured
    • High levels of flexibility means the membrane is resistant to movement and fissures in the substrate
    • Excellent resistance to the high alkalinity of concrete
    • Third-party test certification for radon, carbon dioxide and hydrocarbon gases
    • The Newton HydroBond™ System completely encapsulates and protects the structure

    Typical Applications

    • As a continuous membrane to permanent raft and wall formwork such as the raft blinding and piled walls of reinforced concrete and earth-retained structures

    Suitable Substrate


          • Concrete blinding
          • Compacted type 1 hardcore
          • Compacted sand

        The following can be placed above the blinding or hardcore prior to the installation of 403 HydroBond:

      • Void former
      • Clay heave board
      • Closed-cell flooring grade insulation
      • Closed-cell flooring grade insulation


    • Secant or contiguous concrete piles
    • Metal sheet piles
    • Diaphragm walls
    • King post wall
    • Sufficiently stable ground such as clay or chalk
    • Temporary timber shuttering/formwork
