Waterproofing Systems / System 400 / Newton 403 Hydrobond


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

    The 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
