Brett Landscaping returns to Mansfield for further permeable paving SuDS solutions

Project: Mansfield Sustainable Flood Resilience Commercial Program.

Client: Severn Trent Water & Galliford Try

Sites & product supplied: Coal Authority Mansfield – Invicta Citrine & Omega Flow Charcoal; Magistrate Court Mansfield – Invicta Flow Citrine & Pearl & Omega Flow Charcoal; Mine Rescue Mansfield – Invicta Flow Pearl & Omega Flow Charcoal

 

Brett Landscaping has returned to complete three further key concrete permeable block paving installations as part of the £76m Mansfield Flood Resilience Scheme. 

Brett Landscaping has supplied the Invicta permeable paving, along with swales and planters to be installed at three prominent sites in the town of Mansfield, including the Coal Authority building, Magistrates Court and the headquarters of Mine Rescue.

The Brett team continued to advise Severn Trent, while working with Metis Consulting and the main contractor Ground Control and subcontractor Mac Groundworks to develop the installation and detailing of EV charging bays, disability parking bays and motorcycle bays at these three busy sites that are open to the public.

Invicta permeable block paving was used at the Coal Authority site with Omega Flow block paving used at the Magistrate Court and Mine Rescue sites.

 

 

These product systems were selected for their interlocking ‘male’ and ‘female’ nib that provides additional structural interlock to prevent movement and deformation of the paving in the event of jointing material loss.

Brett Landscaping has previously supplied a wide range of permeable paving for the retrofit of a number of residential parking sites, to meet the access and parking needs of local residents while also capturing surface water to be taken back to ground.

 

 

As well as supplying permeable paving, Brett Landscaping’s experts provided technical support and advice to the scheme’s design team – which included Severn Trent, ARUP, AECOM and Galliford Try – to assist with the design, construction and maintenance of the systems. 

Brett Landscaping’s experience on the public realm elements of the wider scheme meant that the team was well placed to advise contractors on the transition to the single commercial sites, providing Toolbox Talks on the installation, maintenance and detailing of the permeable paving for an effective long-lasting system.

Brett’s team attended pre-site meetings with the contractors and subcontractors to discuss the challenges on site and devise solutions for the installation.

 

 

These commercial installations are the latest phase in the UK’s largest sustainable drainage systems scheme. Across the town of Mansfield surface water drainage systems that can hold 58 million litres of water have been installed to reduce flood risk throughout the town, as part of a £76 million investment package approved under the Ofwat Green Recovery Programme.

Severn Trent and local authorities are working on retrofitting a series of SuDS measures across the Nottinghamshire town including bioswales, detention basins, raingardens, and approximately 50,000m² of permeable paving.

Part of the sustainable flooding resilience project involves retrofitting permeable paving, within highway land such as residential parking areas to tackle the runoff of surface water. The permeable paving has been designed as either infiltrating with a geotextile base or non-infiltrating with an impermeable liner with a return to the sewer system.

The scheme won the ‘Climate Resilient Built Environment Award’ at the 2024 Flood and Coast Excellence Awards.
