{"product_id":"riw-waterstop","title":"RIW Waterstop","description":"\u003cp\u003eRIW Waterstop is a simple yet highly effective solution for waterproofing construction joints in reinforced concrete structures. Rather than relying on a passive mechanical barrier, the sodium bentonite core swells on contact with water, generating a self-sealing pressure seal that tightens under hydrostatic load. This active swelling mechanism maintains an impermeable barrier throughout the life of the structure and accommodates minor joint movement without compromising performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSwells on contact with water\u003c\/li\u003e\n\u003cli\u003eResists 70m head of hydrostatic water pressure\u003c\/li\u003e\n\u003cli\u003eSimple and quick to install\u003c\/li\u003e\n\u003cli\u003eReplaces passive PVC\/rubber waterbars — no special pieces or seam welding required\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\u003eUsed as part of the RIW Structureseal sodium bentonite waterproofing system\u003c\/li\u003e\n\u003cli\u003eRIW Waterstop is not designed or intended to function as an expansion joint sealant.\u003c\/li\u003e\n\u003cli\u003eFor construction joints within reinforced concrete basements and sub-structures\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RIW","offers":[{"title":"Default Title","offer_id":57127688569164,"sku":"BM05723","price":91.35,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1046\/6715\/2716\/files\/riw-riw-waterstop-1232467470.jpg?v=1776259955","url":"https:\/\/www.constructionsuppliesuk.co.uk\/products\/riw-waterstop","provider":"Construction Supplies UK","version":"1.0","type":"link"}
