THE HYDRO Stormbloc® modular underground storage and infiltration system has been awarded prestigious British Board of Agrément(BBA) certification following a rigorous independent testing and validation programme.

The endorsement confirms that cellular design of Stormbloc® meets high product performance specifications and quality manufacturing standards, backed by physical testing witnessed by the BBA and auditing of the Stormbloc® production facilities.

“This long-awaited BBA award provides a mark of confidence for specifiers and contractors that Stormbloc® is independently verified to meet the claims we make for it against a thorough performance checklist,” said Alex Stephenson, Stormwater Director of Hydro International.

“Since its introduction in 2003 Stormbloc® has remained among the market-leading high-capacity modular block infiltration systems. We are delighted that the BBA certification now provides extra reassurance that Stormbloc® will continue to perform to the stringent standards we expect from it.”

Hydro Stormbloc® is the only modular block-based infiltration system with a patented inspection and maintenance tunnel running through each block, enabling the entire volume of the construct to be camera inspected and flushed out if necessary. The clear flow path makes Stormbloc® considerably less prone to silting up or blockage compared to other systems.

The extremely strong plastic block with a 95% void ratio offers space-saving advantages and can be combined with natural drainage and conveyance solutions as part of mixed Sustainable Drainage Systems (SUDS) schemes.

Quick and easy to install, Stormbloc® is suitable for residential, industrial or commercial developments and is strong enough to withstand traffic loads under roads and vehicle parks, driveways or landscaped areas.

Hydro International has already achieved BBA certification for its STH range of Hydro-Brake® Flow Controls and these can be used with Stormbloc® to provide a BBA certified stormwater control package. The Hydro-Brake® is still the only vortex flow control device with BBA certification.
