Self-Adhesive, Post-Applied Waterproofing Membrane - Newton HydroBond SA

Newton HydroBond SA is a high performance, self-adhesive membrane for the external waterproofing of below-ground structures such as basements, water holding tanks and culverts. A composite of cross-orientated HDPE and bitumen polymer adhesive, the membrane is post-applied to concrete after removal of formwork, or to built walls such as block or ICF. The membrane is flexible and durable and exhibits high resistance to impact, tear, puncture and settlement.

This combination of high strength and high flexibility results in excellent crack-bridging capability at places where cracks will occur within the concrete. The bitumen polymer adhesive provides a very high strength bond to the substrate at temperatures as low as 5oC with exceptional peel adhesion qualities, so preventing the migration of water between correctly prepared substrate and the membrane. The product has been tested for water tightness at the laps as per the requirements of BS8102:2022 section 8.2.2 and can be considered fully bonded as per figure 9 of the British Standard.

Newton HydroBond SA overlaps with the pre-applied HydroBond membranes installed below the concrete raft to provide a complete waterproof envelope to the structure to achieve Type A (barrier) waterproofing suitable for Grades 1a, 1b, 2 and 3 as defined by BS 8102:2022.

The membrane is suitable for all below-ground and earth-retained structures from domestic basements to the largest civil engineering projects. Where additional protection against ground gasses is required, Newton HydroBond SAGM should be used.

Newton HydroBond SA can be used alongside other Newton products to provide a coordinated and combined approach to the waterproofing of the whole structure that includes protection against water penetrating through construction joints, through and around service entries and to movement joints.

Correctly protected, the Newton HydroBond System will provide, under normal service conditions, a durable waterproof barrier for the life of the building to which it is installed.
