YOUR ROOFING AND WATERPROOFING PARTNER T: 0845 1948727 3 Introduction Lifetime economies, environmentally sound The Duoflex® Structural Waterproofing System is a hot-melt system, which provides a strong, durable, flexible, lightweight and self-healing monolithic barrier to the transmission of water and water vapour. Designed to last the lifetime of the structure to which it is applied, it eliminates future maintenance and gives rise to particularly low life cycle costs. Duoflex is an environmentally friendly formulation of rubberised bitumen, modified with SBS styrene butadiene polymer resins,...

The convenient installer-friendly system Duoflex can be applied in temperatures as low as -15°C. During installation, it does not release any toxic gases or harmful geneticallymodifying agents; nor does it contain any VOCs (Volatile Organic Compounds). The system requires no curing or on-site mixing and is unaffected by bad weather almost directly after application. Laying Duoflex at perimeter upstands and areas of complex detailing can be completed first. This allows work associated with other trades (such as brickwork, curtain walling, rainscreen systems, rendering, etc) to take place, using...

Lifetime performance – for long term peace of mind The Duoflex waterproofing system is designed to last the lifetime of the structure to which it is applied and is covered by our insurance-backed Sopracover warranty scheme. The entire Duoflex waterproofing system is BBA certified. Self healing of minor damage – no hidden leaks The Duoflex membrane never fully cures, allowing any minor penetrations to the membrane to self heal during usual diurnal temperature changes and under pressure. Fully bonded – makes a monolithic construction Duoflex is 100% bonded to the roof deck to provide a monolithic...
