The primary function of the FoamStop is to act as a depth gauge and bond breaker, ensuring that liquid waterproofing membranes like Newton FlexProof 106 are applied at the correct design thickness. Because it is closed-cell, it does not absorb water and provides a stable, non-adherent base that prevents \"three-sided adhesion,\" allowing the sealant above to expand and contract freely with the building’s movement.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eEnsures precise depth control for liquid-applied joint sealants\u003c\/li\u003e\n\u003cli\u003eActs as a bond breaker to allow for maximum membrane elasticity\u003c\/li\u003e\n\u003cli\u003eHighly compressible and flexible, easily conforming to irregular joint widths\u003c\/li\u003e\n\u003cli\u003eClosed-cell structure prevents moisture absorption and air bubbling in the sealant\u003c\/li\u003e\n\u003cli\u003eChemically inert and compatible with cold-applied sealants and membranes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eGood to know\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-path-to-node=\"5,0,0\"\u003eAvailable in 10mm, 15mm, 20mm, 25mm, 30mm, 40mm, 50mm, and 75mm diameters\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,1,0\"\u003eSupplied in 1m lengths (standard for easy handling and installation)\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,2,0\"\u003eThe diameter of the FoamStop selected should be approximately 150% of the width of the joint (e.g., use a 15mm rod for a 10mm joint)\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,3,0\"\u003eCan be inserted using a blunt tool to avoid piercing the cells; ends should be butted tightly together without the need for adhesive\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Newton Waterproofing","offers":[{"title":"10mm x 1m","offer_id":57286761611596,"sku":"BM06395","price":1.01,"currency_code":"GBP","in_stock":true},{"title":"15mm x 1m","offer_id":57286761644364,"sku":"BM06396","price":1.19,"currency_code":"GBP","in_stock":true},{"title":"20mm x 1m","offer_id":57286761677132,"sku":"BM06397","price":1.27,"currency_code":"GBP","in_stock":true},{"title":"25mm x 1m","offer_id":57286761709900,"sku":"BM06398","price":1.45,"currency_code":"GBP","in_stock":true},{"title":"30mm x 1m","offer_id":57286761742668,"sku":"BM06399","price":1.52,"currency_code":"GBP","in_stock":true},{"title":"40mm x 1m","offer_id":57286761775436,"sku":"BM06400","price":1.63,"currency_code":"GBP","in_stock":true},{"title":"50mm x 1m","offer_id":57286761808204,"sku":"BM06401","price":2.46,"currency_code":"GBP","in_stock":true},{"title":"75mm x 1m","offer_id":57286761840972,"sku":"BM06402","price":6.17,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1046\/6715\/2716\/files\/newton-waterproofing-newton-foamstop-backing-rod-1232467105.png?v=1776262067","url":"https:\/\/www.constructionsuppliesuk.co.uk\/products\/newton-foamstop-backing-rod","provider":"Construction Supplies UK","version":"1.0","type":"link"}
