Newton HydroBond SAGM is a Self-Adhesive Gas & Waterproofing Membrane. A high performance, self-adhesive membrane for the external waterproofing and gas proofing of habitable below-ground structures. 

A composite of polythene and aluminium, coated on one side with a bitumen polymer adhesive, the membrane is post applied to concrete, after removal of form-work, 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 bond to the substrate at temperatures as low as 5°C with exceptional peel adhesion qualities, and so prevents migration of water between correctly prepared substrate and the membrane.

Newton HydroBond SAGM overlaps with the pre-applied Newton HydroBond 403 Plus GB, installed below the concrete raft to provide a complete waterproof and gas-proof envelope to the structure to achieve Type A (barrier) waterproofing suitable for Grades 1, 2 and 3 as defined by BS 8102:2022 and gas protection to BS 8485:2015. The membrane is suitable for all belowground and earth-retained structures from domestic basements to the largest civil engineering projects. Where additional protection against ground gasses is not needed, Newton HydroBond SA may be used. Newton HydroBond SAGM 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.

 Key Benefits: 

  • Type A (barrier) waterproofing membrane 
  • Resistant to aggressive ground water chemicals 
  • Effective barrier to all ground gasses 
  • Dimensionally stable and flexible for easy detailing 
  • Quick and simple to install – no jointing tapes 

Typical Applications: 

  • Post-applied sheet waterproofing to retaining walls of below-ground structures 
  • Used in conjunction with Newton HydroBond pre-applied membranes to provide continuous Type A waterproofing around the whole structure 

Suitable Substrate: 

  • Reinforced concrete 
  • Correctly prepared walls of block and Insulated Concrete Formwork (ICF) 
  • Prepared steel 

Packaging: 

Newton HydroBond SAGM is supplied in 19.05 m long rolls x widths of 1.05 m. Newton HydroBond SAGM Detail Strip is 300mm wide and supplied at lengths of 20 m. Newton HydroBond SA LT Primer is supplied in 5 litre containers.
