It provides a durable water and water vapour barrier for a wide range of below-ground and ground-level applications.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eTypically used for external and internal basement tanking, retaining walls, ground floor damp proof membranes and reservoirs, the membrane is particularly well suited to large unobstructed areas. Applied correctly, it is capable of providing the levels of protection required for Grade 1, 2 and 3 basements as classified under BS 8102:2009 (Type A barrier protection). It is suitable for application to concrete, masonry, steel and insulation board\/ICF systems.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe membrane is 1.6mm thick overall, with 300% elongation and a puncture resistance of 230N, providing a robust and flexible barrier that will perform for the life of the structure when correctly protected. A selvedge strip on each roll ensures clean, reliable lap sealing. Sheetseal 226 holds BBA Certificate No. 92\/2817 covering use for waterproofing above, at and below ground level.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eProvides a reliable water and water vapour barrier for basement tanking, retaining walls and ground floor DPM applications\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eCold-applied with no drying time required — installation can proceed immediately after laying\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eElastic and flexible with 300% elongation, accommodating minor substrate movement without compromising the waterproof seal\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eSelf-healing properties help maintain integrity if the membrane is punctured or damaged during installation\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eFactory-controlled thickness ensures consistent performance across the whole installation\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eSulphate resistant, making it suitable for use in aggressive ground conditions\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\u003e Do not attempt to apply the membrane at temperatures below +5°C — this applies to both the membrane and the primer\u003c\/li\u003e\n\u003cli\u003eA primer (Sheetseal Primer) must be applied to all vertical or inclined surfaces before laying — allow 2 to 4 hours drying time before overcoating, and do not leave the primed surface exposed for more than 7 days.
