BBA accreditation for Tarmac SuDS system
Tarmac's porous asphalt system, TarmacDry, has become the first product of its kind to be awarded BBA (British Board of Agrément) accreditation.
Designed for lightly-trafficked areas, TarmacDry can be used as part of Sustainable Drainage Systems (SuDS) to capture rain and surface water before storing it for recycling, performing a controlled discharge into the primary drainage system, or gradually releasing it into the sub-grade.
The BBA accreditation assessed the system's mechanical resistance, hydraulic performance and durability at two trial locations in Bristol and Bolton.
James Freeman, national special products manager for Tarmac, said the accreditation would give architects, engineers and contractors added assurance that TarmacDry is an effective water-management system, either on its own or as part of a wider SuDS system.
'The likely introduction of the Draft Floods and Water Bill later this year will have far-reaching implications for how surface water is controlled,' he commented. 'It is vital, therefore, that the construction industry can draw upon a proven pavement technology to help mitigate flood risk by designing porous surfacing into all developments.'
TarmacDry is supplied and installed throughout the country by Tarmac National Contracting.
