At SOPREMA, we pride ourselves on creating waterproofing systems that boast durability. One of our most durable systems is DUOFLEX Structural Waterproofing, which is a hot melt, liquid applied system that is BBA certified to last the lifetime of the structure it is applied to. If you’re unfamiliar with DUOFLEX, here are some of the key elements that make it an invaluable roofing system.
Zero Fall Application
When working on zero fall roofing, it’s vital that ponding water cannot penetrate the substrate. DUOFLEX is based on SBS modified bitumen and forms a strong, self-healing monolithic barrier. The system is also BBA certified for installation at zero falls. All of this ensures that DUOFLEX performs well on flat roofs.
Further to this, DUOFLEX can also be specified in conjunction with a green roof system when the Sopralene Flam Garden 250 anti-root capsheet is incorporated. A green roof helps transform a zero fall roof into a well-utilised space that promotes sustainability.
Phased Works
DUOFLEX is ideal for use in phased works, as water cannot track underneath the system due to the monolithic bond DUOFLEX forms with the substrate when it is applied. This barrier can also be installed in temperatures as low as -15C – so projects are not halted if temperatures plummet.
Reduced Project Cost
DUOFLEX requires just 6kg of material per m², and does not require neoprene detailing due to its quality. By reducing the amount of bulk material required and avoiding the need to buy additional detailing supplies, DUOFLEX delivers a more cost-effective waterproofing solution.
Durability & Performance
DUOFLEX is BBA certified to last for the whole lifetime of a structure, ensuring lasting durability over many years. The wording states: “The system, when fully protected and subject to normal service conditions, will provide an effective barrier to the transmission of liquid water and water vapour for the design life of the structure in which it is incorporated.” DUOFLEX also offers a self-healing barrier against minor penetrations, which keeps maintenance requirements at bay.
SOPREMA Warranty
SOPREMA offers a 40-year warranty for our DUOFLEX system. This warranty reflects our commitment to product quality and highlights the durability of DUOFLEX.
