SOPREMA DuoFlex Systems Achieve UK BBA Accreditation

SOPREMA, a global leader in waterproofing, roofing, thermal and acoustic insulation solutions, has announced that its innovative DuoFlex hot melt single pour system has received UK BBA (British Board of Agrément) accreditation.

This esteemed accreditation endorses DuoFlex for a variety of applications including weatherproofing inverted roofs, zero fall roofs, roof gardens, blue roof specifications in combination with stormwater attenuation systems, and protected roofs with limited access in flat roof specifications.

Comprehensive System Solution

The DuoFlex structural waterproofing systems by SOPREMA meet the rigorous demands of today’s evolving building environments. It comprises a complete offering of primers, waterproofing, protection sheets and accessories, providing high performance solutions for new build and refurbishment flat roofing applications.

Key benefits of DuoFlex roofing systems include:

Unrestricted Classification

DuoFlex systems meet the highest fire resistance standards, classified as unrestricted. This is achieved with the following configurations:

Loose laid gravel with a thickness of at least 50 mm or a mass greater than 80 kg/m2 (minimum aggregate size 4 mm, maximum 32 mm).
Sand/cement screed to a thickness of at least 30 mm thick.
Cast stone or mineral slabs at least 40 mm in thickness.

Extended Warranties

SOPREMA offers substantial warranties for its DuoFlex systems, underscoring their reliability and longevity. The single pour system comes with a 30-year warranty, while the double pour system boasts and impressive 40-year warranty.

Optimum Adhesion

The hot liquid application of DuoFlex systems forms a highly robust fully bonded substrate on the surface of the roof structure, effectively becoming a fully integrated part of the construction materials.

Monolithic and Self-Healing Capabilities

The DuoFlex systems are both monolithic and self-heating, due to its permanent, flexible elastomeric properties. This provides a seamless high quality waterproof barrier which can repair small surface penetrations itself, enhancing durability and ensuring long-term performance.

Fast Track and Phrased Installations

DuoFlex systems accommodate fast-track robust waterproofing and phased construction installations, making them an ideal choice for projects with complex requirements and tight schedules.

Durability and Sustainability

A significant advantage of the DuoFlex systems is their contribution to sustainability. The long service life of these products means fewer replacements and repairs over the lifespan of the structure, which translates into reduced material consumption and waste. This durability aligns with modern building practices, supporting the construction of long-lasting sustainable structures.

Pre-Application with Sopradvance

Prior to the application of DuoFlex products, SOPREMA recommends the application of Sopradvance, a specialised primer that enhances adhesion, ensuring optimal performance of the DuoFlex systems. This step is crucial for achieving the best results in waterproofing and durability.

Versatile Applications

SOPREMA DuoFlex systems are highly versatile and adaptable to a range of roofing and waterproofing needs:

Inverted Roofs

Ideal for inverted roofs where insulation installed above the waterproofing layer, DuoFlex ensures robust protection against water ingress.

Roof Gardens

In roof garden applications, DuoFlex provides a reliable waterproof barrier that supports the growth of vegetation while protecting the underlying structure.

Blue Roofs with Stormwater Attenuation

DuoFlex is compatible with blue roof specifications, designed to manage stormwater. The system helps control water runoff, reducing the risk of flooding and supporting sustainable urban drainage systems (SUDS).

Protected Roofs with Limited Access

For roofs with limited access, DuoFlex delivers dependable waterproofing that withstands the elements, ensuring the longevity and integrity of the roof structure.

Industry Recognition

The BBA certification is a testament to the quality and performance of the DuoFlex hot-melt single pour systems. The rigorous testing and evaluation process conducted by the BBA confirms that DuoFlex meets the highest standards for waterproofing and durability.

Technical Service

Technical industry expertise is a key strength of SOPREMA. Our experienced technicians are available to assist with site inspections (initial survey, interim and completion), provide detailed project calculations (rainwater, wind uplift etc.) and specifications (CAD drawings), core sampling, condition reports, design consultation and advice for new build projects. Educational seminars, product and application training can also be organised.

Conclusion

The UK BBA accreditation of SOPREMA’s DuoFlex hot melt systems marks a significant milestone in roofing and waterproofing solutions.
