Proteus, one of the UK's fastest growing waterproofing companies, has announced the launch of a new kind of roof system.
It is called Attenu8® and features a patented blue roof system as part of a total package that is set to redefine stormwater management in urban environments, by offering a unique approach to rainwater attenuation - which differentiates it from all other conventional blue roof solutions currently available in the market.
Traditional blue roof systems rely on the primary roof waterproofing membrane to temporarily hold rainwater, subjecting this critical building component to constant hydrostatic pressure. Attenu8®'s advanced design incorporates an entirely separate, engineered reservoir system positioned above the main roof waterproofing membrane. This means the building's core waterproof layer remains dry under normal operating conditions, acting as a crucial secondary defence rather than the primary water containment.
The Attenu8® system integrates sophisticated, purpose-designed drainage components from a specialist, alongside its patented blue roof system, to create a dedicated, independent attenuation zone. Water entering this upper reservoir is precisely managed and released at a controlled, pre-determined rate via a calibrated outflow restrictor. The integrity of this primary containment is maintained by the reservoir's design and its integrated drainage components.
Only in the most extreme or unforeseen circumstances, such as a major 100-year rainfall event exceeding design capacity in the primary reservoir, would water contact the main waterproofing membrane. Even then, this independently installed membrane provides an additional, impermeable safeguard. This two-tiered containment strategy is unique to Attenu8®, offering enhanced security and peace of mind for building owners.
By protecting the main membrane from constant water exposure, the system significantly extends its lifespan, reducing long-term maintenance costs and potential disruptions. The precise control over water release aids compliance with stringent planning regulations and contributes directly to urban flood mitigation efforts. The inherent redundancy of the dual system enhances reliability, minimising the risk of water ingress and costly damage.
Proteus Waterproofing supports every Attenu8® installation with comprehensive design and technical assistance from project initiation. The Attenu8® system is the complete bespoke build-up and includes waterproofing, insulation, the patented and unique Blue roof, together with finishes such as hard pavers, ballast or Green roof. It can also include solar, all designed by the Proteus team.
Furthermore, Attenu8® is installed exclusively by licensed contractors who undergo rigorous, specialised training provided by Proteus Waterproofing. This controlled installation network guarantees adherence to the highest quality standards, ensuring the system's engineered benefits are fully realised and maintained throughout its operational life.
Attenu8® represents a strategic investment for building owners and developers seeking a robust, reliable, and high-performance solution for urban stormwater management. Its unique design and integrated support set a new standard for blue roof technology, providing long-term resilience and value.
