Externally Applied Waterproofing Membrane: Newton 403 HydroBond
Newton 403 HydroBond is a very high performance composite sheet membrane that features a locking fleece to one side and a polymer hydrophilic coating to the other.
When placed below the new raft or against permanent shuttering, the Newton 403 HydroBond fibres are encapsulated into the wet concrete becoming monolithic to the surface. The fully engaged membrane prevents water tracking to the joints in the structure, should there be a defect.
Full mechanical bond to concrete prevents water migration between membrane and structure
Hydrophilic coating provides self healing of punctures to the membrane
Very flexible Resistant to movement and fissures in substrates.
Applied under the raft and to the walls to fully encapsulate the structure.
Excellent resistance to the high alkalinity of concrete.
