Manufactured from 100% recycled High-Density Polyethylene (HDPE), it offers a sustainable yet heavy-duty solution for managing water ingress in \"Type C\" waterproofing systems. Its deep profile provides a significantly larger drainage void than standard 8mm membranes, making it the preferred choice for projects where a high volume of water is anticipated or where a larger safety margin is required. It is BBA-certified, guaranteed for 30 years, and forms a critical part of a maintainable internal drainage system.\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\"\u003eExceptional drainage capacity due to the deep stud profile\u003c\/li\u003e\n\u003cli data-path-to-node=\"3,1,0\"\u003eSustainable construction: made from 100% recycled HDPE and fully recyclable\u003c\/li\u003e\n\u003cli data-path-to-node=\"3,2,0\"\u003eHigh compressive strength, capable of supporting heavy floor loads and screeds\u003c\/li\u003e\n\u003cli data-path-to-node=\"3,3,0\"\u003eInert and highly resistant to water, alkalines, organic acids, and hydrocarbons\u003c\/li\u003e\n\u003cli data-path-to-node=\"3,4,0\"\u003eForms a vapor-proof barrier that protects floor finishes from dampness and ground gases\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=\"5,2,0\"\u003eHeaviest in the range with a density of 1000g\/m²\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,3,0\"\u003eOften used in conjunction with Newton Fibran XPS 500-C insulation for a warm, dry floor build-up\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,4,0\"\u003eCan be used as a gas barrier when joints are correctly sealed with Newton CDM Waterseal Tape\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Newton Waterproofing","offers":[{"title":"2m x 10m","offer_id":57287645036876,"sku":"BM06168","price":149.58,"currency_code":"GBP","in_stock":true},{"title":"2m x 20m","offer_id":57287645069644,"sku":"BM06090","price":200.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1046\/6715\/2716\/files\/newton-waterproofing-newton-cdm-520-eco-cavity-drain-floor-membrane-1232467326.jpg?v=1776255456","url":"https:\/\/www.constructionsuppliesuk.co.uk\/products\/newton-cdm-520-eco-cavity-drain-floor-membrane","provider":"Construction Supplies UK","version":"1.0","type":"link"}
