By exploiting the system’s open-cell design, which has been back-filled with soil and sown with grass, the car park has a porous, high load bearing finished surface that not only blends perfectly with the surroundings but also does not require any additional drainage infrastructure to manage any of its surface water run off.
The car park serves a new £500k community centre that now occupies the site of the village’s old cricket pavilion. A much needed resource for the area, the new 350sqm centre is multi-functional providing pre-school nursery, sports and social facilities.
The project has been part-funded by the National Lottery, the Bishop Wilton Village Hall Association and WREN (Waste Recycling Environmental Limited) - a not-for-profit business that awards grants for environmental, heritage and community projects.
The challenge facing the centre’s designers was to realise a scheme that would meet the demanding environmental brief. “As the comparatively large car parking area sits on the boundary of the village conservation area we needed a cost-effective solution that could meet the planning requirements, blend with the rural setting, be sustainable and, ultimately, be capable of handling a wide range of passenger and commercial vehicles,” explains Peter Goodrick, Senior Project Manager at Turner & Townsend, construction management consultants for the project. “I was familiar with ACO GroundGuard from a recent successful university project where we had used a grass back-fill. Here, by matching the seed variety to that of the adjacent fields, we have created a durable, high performance surface that is indistinguishable from its surroundings.”

ACO GroundGuard is manufactured from 100% recycled polyethylene in lightweight tiles 38mm deep, 585mm long and 385mm wide. Installation requires a well compacted angular gravel sub-base topped with sand which provides a good root bed for the seeded grass. Once the groundworks are complete, individual GroundGuard tiles are simply clipped together and outer edges cut or trimmed to the required finished shape.
North Yorkshire-based contractor, Dobsons Civil Engineering & Construction, completed the car park phase.
“This was the first time we had worked with any ground stabilisation system on this scale,” says Sam Dobson, Contracts Director. “Finding the GroundGuard tiles easy to handle, lay and cut we were soon achieving installation rates in excess of expectations. We completed the area ahead of schedule, creating valuable additional vehicle space for the site which suffered from restricted access and very limited on-street parking.”
Recognised by the Association of Professional Landscapers, ACO GroundGuard’s ‘honeycomb’ structure is capable of supporting loads of up to 250 tonnes per square metre, making it ideal for many applications, including caravan parks, golf courses, stable blocks, helipads, access routes and driveways. It is also used extensively to create pedestrian pathways and wheelchair accesses compliant with Part M of the Building Regulations.
