It consists of a high-density polyethylene (HDPE) core with studs on both the upper and lower surfaces, and a non-woven polypropylene geotextile filter layer thermally bonded to the upper cuspates. This unique \"double-cuspated\" design ensures a clean drainage path both above and below the membrane, preventing water from becoming trapped against the primary waterproofing layer. It effectively manages surface water while filtering out fine soil particles, making it essential for complex roof build-ups.\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-layered drainage paths prevent water stagnation on the primary waterproofing membrane\u003c\/li\u003e\n\u003cli data-path-to-node=\"3,1,0\"\u003eIntegrated geotextile layer filters out fines to prevent drainage system blockages\u003c\/li\u003e\n\u003cli data-path-to-node=\"3,2,0\"\u003eHigh compressive strength supports heavy finishes like block paving and stone slabs\u003c\/li\u003e\n\u003cli data-path-to-node=\"3,3,0\"\u003eFacilitates the creation of intensive green roofs and large planters on flat structures\u003c\/li\u003e\n\u003cli data-path-to-node=\"3,4,0\"\u003eQuick and easy to roll out, providing immediate protection to the waterproofing layer\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 rolls of 2.0m x 20m (40m² coverage)\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,1,0\"\u003eProduct Code: M33\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,2,0\"\u003eSpecifically designed to be laid directly over a primary deck waterproofing membrane\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,3,0\"\u003eSuitable for use in NHBC-compliant drainage detailing\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,4,0\"\u003eCan also be used as a vertical drainage layer for externally applied basement waterproofing\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Newton Waterproofing","offers":[{"title":"Default Title","offer_id":57222346408268,"sku":"BM06097","price":278.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1046\/6715\/2716\/files\/newton-waterproofing-newton-newseal-408-deckdrain-flat-roof-drainage-membrane-1232467322.jpg?v=1776255511","url":"https:\/\/www.constructionsuppliesuk.co.uk\/products\/newton-newseal-408-deckdrain-flat-roof-drainage-membrane","provider":"Construction Supplies UK","version":"1.0","type":"link"}
