When embedded into a wet liquid membrane, the fleece edges bond to the substrate while the central rubber span remains unbonded. This creates a defined slip zone over control joints, substrate abutments, and expansion joints. By preventing the liquid membrane from bonding directly to the moving joint, the band redistributes localized stress across its 70mm rubber width, accommodating multi-directional movement with up to 100% elastic recovery without tearing.\u003c\/p\u003e\n\n \u003ch3\u003eNumbers that matter\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eUp to 100% elastic recovery:\u003c\/strong\u003e Absorbs repeating lateral, longitudinal, and transverse building movement at wall\/floor junctions without permanent deformation.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003e3 bar water pressure resistance:\u003c\/strong\u003e Seals reliably under hydrostatic load, making it suitable for water storage and areas subject to full immersion.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003e20mm maximum starting joint width:\u003c\/strong\u003e Accommodates joint movement up to 50% of this starting width, preventing rupture over active structural gaps.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003e-20°C to 90°C temperature resistance:\u003c\/strong\u003e Maintains physical properties behind tiles in extreme service environments, from exterior freeze-thaw cycles to hot commercial drainage.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003e0.6mm to 0.8mm thickness:\u003c\/strong\u003e Low-profile build that minimizes thick build-ups under floor tiles and wall linings, simplifying subsequent screeding or tiling.\u003c\/li\u003e\n \u003c\/ul\u003e\n\n \u003ch3\u003eWhere to use it\u003c\/h3\u003e\n \u003cp\u003eThis joint band is suitable for residential, commercial, and industrial waterproofing applications.
