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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-path-to-node=\"3,0,0\"\u003eDual-action protection provides a reliable barrier against both groundwater and hazardous ground gases\u003c\/li\u003e\n\u003cli data-path-to-node=\"3,1,0\"\u003eFully-bonded system prevents water or gas migration behind the membrane in the case of a puncture\u003c\/li\u003e\n\u003cli data-path-to-node=\"3,2,0\"\u003eHigh flexibility and elongation allow the membrane to bridge minor cracks and settlement in the structure\u003c\/li\u003e\n\u003cli data-path-to-node=\"3,3,0\"\u003eCold-applied and self-adhesive for a safe, fast installation without the need for specialist heat equipment\u003c\/li\u003e\n\u003cli data-path-to-node=\"3,4,0\"\u003eAdvanced adhesive achieves a high-strength bond at temperatures as low as 5°C for year-round application\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eGood to know\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-path-to-node=\"5,0,0\"\u003eSupplied in 1.00m x 20.00m rolls providing 20 square metres of coverage\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,1,0\"\u003eProduct code 401-GM\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,2,0\"\u003eSubstrates must be prepared with Newton HydroBond SA Primer LT to ensure maximum adhesion\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,3,0\"\u003eCompatible with HydroBond SAGM Detail Strip for reinforcing wall-to-foundation joints and corners\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,4,0\"\u003eHighly resistant to aggressive groundwater chemicals and soil contaminants\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Newton Waterproofing","offers":[{"title":"Default Title","offer_id":57211599716684,"sku":"BM06078","price":296.44,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1046\/6715\/2716\/files\/newton-waterproofing-newton-hydrobond-sagm-external-waterproofing-gas-membrane-1232467334.jpg?v=1776255674","url":"https:\/\/www.constructionsuppliesuk.co.uk\/products\/newton-hydrobond-sagm-external-waterproofing-gas-membrane","provider":"Construction Supplies UK","version":"1.0","type":"link"}
