Liquid-Applied Roof Waterproofing Proven Experience Technical Expertise Waterproofing Solutions Exceptional Performance Quality
Liquid applied waterproofing from Icopal Introduction Based on polyurethane resin technology, the Elastoflex range of liquid waterproofing membranes from Icopal offers the professional specifier, quality materials with a proven track record. Available as either a single component solvented coating or as a solvent free two component coating, Elastoflex membranes are designed primarily for use within the commercial refurbishment and new build sectors. Advantages of Liquid Applied Membranes Projects with difficult access, restrictive clearances, multiple or odd-shaped penetrations can prove very challenging for even the most adaptive roofing membranes. In such cases, a liquid applied option is an excellent alternative. Used in its own right or in conjunction with Icopal s range of high performance roofing membranes, Elastoflex liquid waterproofing membranes benefit from wet-on-wet application, offering greater internal bond strength between coating layers and also faster application times as the primary waterproofing elements are applied in a single operation. Types of Application Elastoflex liquid applied waterproofing systems are ideal for refurbishment projects where more traditional products prove too difficult. Liquid membranes can also be used above insulation as part of a new warm roof construction. Roof Refurb /Overlays Access Balconies New Roof Constructions Access Walkways - Warm Roofs Detail Work, e.g. - Cold Roofs - Upstands - Inverted Roofs - Gutters - Green Roofs External Terraces Elastoflex Systems Features and Benefits: Seamless and lightweight membrane Polyester reinforced Wet-on-wet application Ideal for roofs with complex geometry or multiple penetrations Vapour permeable Life expectancy in excess of 5 years Exceptionally strong
Guaranteed Performance All Elastoflex liquid applied waterproofing systems shown in this brochure are available with a comprehensive 10, 15 or 0 year Icopal insurance backed guarantee covering materials, workmanship, system design, consequential loss and insolvency (depending on system build-up chosen). To qualify for a guarantee, the Elastoflex system must be installed to an Icopal approved specification by a trained Icopal approved contractor. Wet-on-Wet Application Elastoflex liquid applied waterproofing membranes are applied in a wet-on-wet application. The top coat is applied while the reinforced base coat is still wet providing total integration of the two layers into a single, chemically bonded membrane. This application avoids the risk of failure from insufficient coverage, lack of inter-layer adhesion from contamination and even delamination. Since the Elastoflex liquid applied waterproofing membrane is applied in one operation, it allows the installation to be completed more reliably and quicker than other methods. Industry Association Icopal is a member of the Liquid Roofing and Waterproofing Association [LRWA]. As an association, LRWA s guiding principle is to ensure that clients obtain high quality liquid-applied roofing, through a partnership of quality assured manufacturers and contractors. ISO 9001
