It is designed for below-ground waterproofing where higher physical resistance is required — such as beneath heavily loaded raft foundations or in areas with aggressive ground conditions.\u003c\/p\u003e\n\u003cp\u003eLike the A+ 08 grade, the membrane forms a full and permanent dual bond with the structural concrete, preventing lateral water migration between the membrane and the structure. It can be applied pre-cast (laid before reinforcement and concrete) or post-cast to existing concrete surfaces.\u003c\/p\u003e\n\u003cp\u003eThe product is suitable for use as a methane, carbon dioxide, and radon resistant membrane when installed in accordance with BS 8485:2015+A1:2019. It is CE marked to EN 13967 and holds a BBA Agrément Certificate, making it suitable for specification on projects requiring third-party certified waterproofing.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1.2mm membrane thickness for greater physical resistance and durability\u003c\/li\u003e\n\u003cli\u003eFull dual bond (mechanical + chemical) prevents lateral water underflow\u003c\/li\u003e\n\u003cli\u003ePre- or post-applicable for programme flexibility\u003c\/li\u003e\n\u003cli\u003eGround gas (methane, CO₂) and radon resistant per BS 8485:2015+A1:2019\u003c\/li\u003e\n\u003cli\u003eCold-applied installation — no naked flame required\u003c\/li\u003e\n\u003cli\u003eBBA Agrément certified and CE marked to EN 13967\u003cbr\u003e\n\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\u003eFast \u0026amp; easy installation reducing labour costs and time\u003c\/li\u003e\n\u003cli\u003eGood resistance to aggressive conditions in natural ground water and soil\u003c\/li\u003e\n\u003cli\u003eCan be combined with other Sika waterproofing and joint sealing systems\u003c\/li\u003e\n\u003cli\u003eSuitable for horizontal and vertical below-ground applications.\u003c\/li\u003e\n\u003cli\u003e Joints are thermally welded or sealed with SikaProof A+ tape.\u003c\/li\u003e\n\u003cli\u003e Apply to a stable, smooth substrate; ponding water must be avoided\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sika","offers":[{"title":"Default Title","offer_id":57127720550732,"sku":"BM05771","price":843.6,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1046\/6715\/2716\/files\/sika-sikaproof-a-12-1m-x-20m-1232467223.webp?v=1776256189","url":"https:\/\/www.constructionsuppliesuk.co.uk\/products\/sikaproof-a-12-ro-1m-x-20m","provider":"Construction Supplies UK","version":"1.0","type":"link"}
