The ultimate sustainable drainage solution

In response to growing concerns over flood risk management resulting from development, the capacity of our drainage systems and increased weather variability, ULTISuDS porous asphalt is a designed range for use in sustainable drainage systems that meet the requirements of current environmental legislation and reducing the risk of flooding by managing surface water at source.

The ULTISuDS asphalt range is incorporated into porous asphalt designed pavements, such as the parking areas associated with retail and business areas. The asphalt pavement provides a surface water runoff to infiltrate across its entire porous asphalt surface into the granular layers. ULTIFLOW is our range of aggregates for use in SuDS.

ULTISuDS surface coarse asphalts are manufactured with advanced binder technology that when used in conjunction with the specially designed ULTISuDS base/binder, provides effective drainage and maintains long term durability.? ??

ULTISuDS is only available for?installation by Tarmac accredited contractors and has BBA certification

Coloured porous asphalt options are available in our Ulticolour range.

Case studies


ULTISuDS Bristol

Construction of the 2,000m2 car park was a major element of a new purpose built Community Centre, a community-led design and build project


ULTISuDS Berkshire

The University of Reading wanted a product that could tackle storm water management at its campus. This resulted in the first SDS system to combine porous asphalt with an open drainage basin system by Tarmac.


ULTISuDS Car Park B and Q, Portsmouth

The ULTISuDS design incorporated a bespoke infiltration system using a granular reservoir base and the hydraulic performance of each asphalt layer was tested to assess compliance before laying the next


ULTISuDS car park, Glasgow

After looking at various options Glasgow City Council’s final decision was to use ULTISuDS on the car park. This solution met all requirements including those of the Scottish Environment Protection Agency (SEPA).


ULTISuDS car Park, Wigan

To coincide with the opening of its new town centre offices, Wigan Council wanted to upgrade its car park at Chapel Lane. The car park is used by Council employees during the week and shoppers at the weekend


ULTISuDS case study car park, High Wycombe

Johnson and Johnson requested a system that would not simply channel water into the site’s drainage system but continue to allow it to percolate naturally into the ground.


ULTISuDS playground, Birmingham

Crocketts Community School in Smethwick, Birmingham, is an ‘Exemplar Schools Project’, demonstrating a commitment to the highest affordable levels of sustainable construction.


ULTISuDS ULTICOLOUR Community centre, Wolverhampton

ULTISuDS a proven SDS system, was successfully combined with ULTICOLOUR, coloured asphalt to complement the unusual style of building which utilises metal cladding with a red rusty look and feel to it


ULTISuDS Bathgate Case study

The Morrisons Bathgate store requireda SDS compliant system that supported the Scottish Environment Protection Agency (SEPA) two stages of storm water treatment. We were engaged early in project working with on-site engineers Stuart McTaggart to help design the structure and rainwater capacity of the system two years before the work began.
