Description

Newton HydroBond SAGM is a high-performance, self-adhesive "Type A" membrane specifically designed to provide both external waterproofing and robust gas proofing for below-ground structures. This versatile sheet membrane is a composite of cross-oriented HDPE film and a thick bitumen-polymer adhesive, engineered for post-application to concrete, blockwork, or Insulated Concrete Formwork (ICF) walls. In addition to preventing water ingress, the SAGM version provides a certified barrier against harmful ground gases, including Radon, Methane, and Carbon Dioxide. Its advanced adhesive formula ensures a high-strength, fully-bonded seal even in temperatures as low as 5°C, effectively eliminating the risk of water or gas tracking between the membrane and the structure.

Benefits

  • Dual-action protection provides a reliable barrier against both groundwater and hazardous ground gases
  • Fully-bonded system prevents water or gas migration behind the membrane in the case of a puncture
  • High flexibility and elongation allow the membrane to bridge minor cracks and settlement in the structure
  • Cold-applied and self-adhesive for a safe, fast installation without the need for specialist heat equipment
  • Advanced adhesive achieves a high-strength bond at temperatures as low as 5°C for year-round application
