{"product_id":"wykamol-cm8-cavity-drain","title":"Wykamol CM8 Cavity Drain","description":"\u003cp\u003eWykamol CM8 is a Type C cavity drain membrane system for below-ground structures. The 8mm studded HDPE profile holds the membrane away from the substrate, creating a drainage cavity that channels groundwater to perimeter drainage and a sump pump, controlling water ingress rather than resisting it. The clear membrane makes it straightforward to locate and fix CM Brick Plugs during installation.\u003c\/p\u003e\n\u003cp\u003eThe membrane requires minimal surface preparation and can be applied to walls, floors and ceilings. Because no drying-out period is needed, internal finishes and dry lining can be installed immediately after the membrane is in place. Perimeter drainage channels should be installed at the base of walls to optimise water flow towards the sump location.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMinimal surface preparation required\u003c\/li\u003e\n\u003cli\u003eNo drying-out period before applying internal finishes\u003c\/li\u003e\n\u003cli\u003eLow and high temperature tolerance\u003c\/li\u003e\n\u003cli\u003eDurability, will last the lifetime of the structure\u003c\/li\u003e\n\u003cli\u003eWaterproof, salt inhibiting, root and contaminant resistant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGood to know \u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eType C cavity drain system — BS 8102:2022 compliant\u003c\/li\u003e\n\u003cli\u003eBBA certified\u003c\/li\u003e\n\u003cli\u003eStore upright, under cover, away from heat and open flames\u003c\/li\u003e\n\u003cli\u003eTypical applications, internal waterproofing of basement walls and floors — Type C BS 8102:2022, dry lining using timber battens or steel dry lining systems, vaults and tunnels and External foundation waterproofing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Wykamol","offers":[{"title":"Default Title","offer_id":57127680147788,"sku":"BM05996","price":112.3,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1046\/6715\/2716\/files\/wykamol-wykamol-cm8-cavity-drain-1232467445.jpg?v=1776263495","url":"https:\/\/www.constructionsuppliesuk.co.uk\/products\/wykamol-cm8-cavity-drain","provider":"Construction Supplies UK","version":"1.0","type":"link"}
