{"product_id":"damp-proof-membrane","title":"Damp Proof Membrane","description":"\u003cp\u003ePolythene sheet laid under a concrete slab or floor to stop ground moisture rising up through it — the layer that keeps a solid floor dry rather than slowly damp from underneath. Available in 1000 gauge (250 micron) and 1200 gauge (300 micron), both BBA approved; 1000 gauge meets UK Building Regulations' minimum standard, 1200 gauge is the thicker, more robust option for a tougher site or extra peace of mind. Lap joints by at least 150mm and tape them, since a damp proof membrane only works where it isn't torn or gapped.\u003c\/p\u003e","brand":"everythingTimber","offers":[{"title":"DPM 300 Microns 1200g 4m x 25m (BBA Approved)","offer_id":57308473819401,"sku":null,"price":35.99,"currency_code":"GBP","in_stock":true},{"title":"DPM 250 Microns 1000g 4m x 25m (BBA Approved)","offer_id":57308473852169,"sku":null,"price":32.99,"currency_code":"GBP","in_stock":true},{"title":"DPM 300 Microns 1200g 4m x 25m","offer_id":57308473884937,"sku":null,"price":32.99,"currency_code":"GBP","in_stock":true},{"title":"DPM 250 Microns 1000g 4m x 25m","offer_id":57308473917705,"sku":null,"price":29.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/1485\/0825\/files\/damproofmembranerenameonsite.jpg?v=1790815850","url":"https:\/\/everythingtimber.co.uk\/products\/damp-proof-membrane","provider":"EverythingTimber","version":"1.0","type":"link"}
