The centre folded format reduces the risk of cracks in screed and limits creases during installation.\u003c\/p\u003e\n\u003cp\u003eThe membrane is sulphate resistant — when installed with heat welded joints it is suitable for use in aggressive ground conditions across DS classifications 1-5 in accordance with the Aggressive Chemical Environment for Concrete (ACEC) classification system, making it appropriate for sites with elevated sulphate or chemical ground conditions. Lap joints can be heat welded or taped using compatible Visqueen system components including VisqueenPro Double Sided Jointing Tape and VisqueenPro Single Sided Tape. BBA Agrement certified. CE and UKCA Declarations of Performance available.

When hot air hand welding the lap joints, the joint should be overlapped by approximately 100mm and an approximate 35mm weld is normally maintained. During hand welding, the lap joints should be firmly compressed using a hand roller to ensure an adequate bond is achieved.\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Visqueen","offers":[{"title":"Default Title","offer_id":57301784854860,"sku":"BMD11598","price":167.66,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1046\/6715\/2716\/files\/visqueen-membranes-visqueen-high-performance-dpm-500mu-4m-x-12-5m-50m2-1233883876.jpg?v=1776866052","url":"https:\/\/www.constructionsuppliesuk.co.uk\/products\/visqueen-high-performance-dpm-4m-x-125m-x-500mu","provider":"Construction Supplies UK","version":"1.0","type":"link"}
