Tesco Risca

  • Area of Formpave: 10,000m2 +
  • Type of system: Attenuation
  • Contractors: Britannia Construction Ltd
  • Completion: December 2010

Hanson Formpave completed a 761 capacity shoppers’ car park for grocery giant, Tesco, at its 80,000 sq ft superstore in Risca, South Wales.

Appointed by project consulting engineers, Pinnacle, as both paving scheme designer and supplier, Hanson Formpave supplied over 10,000m2 of Aquaflow® permeable paving system and nearly 3,000 l/m of Forest Edging, both in Red Brindle. The paving achieved both a practical and aesthetic car parking facility for the store in Risca.

Flood and surface water issues were a priority for the project team as the superstore sits alongside the River Ebbw. Due to restrictions on outflow from the site, both the Environment Agency and Local Authority were involved, every step of the way.

Britannia Construction Ltd and the Hanson Formpave Design Service team designed a solution using the Hanson Formpave Aquaflow permeable paving SUDS system, to clean the water to a pH neutral standard and eliminate the issue of surface water. Using a sub-base and geotextile layering structure, the tanked system attenuates the water before releasing it back into the watercourse, up to five hours after the peak of the down pour or storm.

Further environmentally friendly aspects included the sub-base stone. The sub-base contained 50% reclaimed crushed concrete from the original structure, floor slabs and foundations at the development.

Groundworks and paving specialist, D20 installed and laid the Hanson Formpave warranted permeable paving SUDS system in each of the car parking bays, creating an attenuation zone across the entire car park.

The multi-million-pound Tesco Extra store formed part of an ambitious regeneration plan for Risca, improving job opportunities and community facilities, whilst also providing a welcome facelift for the Welsh town.
