Terrabase Rustic resin-bound surfacing
Addagrip was delighted to have been involved in the new Broad Walk project at the Royal Botanic Gardens, Kew. An installation of over 3000m2 of the innovative new porous paving system, Terrabase Rustic, was carried out by approved contractor, True Grip Ltd.
The project would create the longest double herbaceous borders in the UK. The 300m long borders situated either side of the Broad Walk from the Orangery to the Palm House Pond, were to be planted with vibrant summer flowering perennials, grasses and bulbs to form a spectacular new horticultural feature.
The first phase of this project began with the resurfacing of the Broad Walk path with a resin-bound gravel surface, edged with brick.
Addagrip were approached as the UK ‘s leading manufacturer of resin exterior surfaces and together with approved contractor, True Grip Ltd, carried out extensive surveys and put together several specification options and costs that Kew could consider.
Kew selected Addagrip’s new patented resin bound surfacing system Terrabase Rustic as it offered a larger 6-10mm stone size providing the rustic looking finish that Kew required. It could also be installed over the existing macadam with minimum environmental impact and disruption. Drainage was another key requirement and the larger stone size of this bound system provides a high degree of porosity.
As the Terrabase product was relatively new, the surface had to meet many exacting performance criteria put forward by Kew, which Addagrip were able to substantiate. After 9 months of discussion, True Grip Ltd were appointed to work via main contractor Kier Facilities Services to install the Terrabase Rustic Oak finish. Despite challenging weather conditions and site restrictions due to the public use of the main areas, True Grip Ltd installed 3,163m2 at a thickness of 40mm over the entire Broad Walk, following behind Kier Facilities Services who were installing extensive drainage services and brick edging.
The new Terrabase Rustic surface is hard wearing, low maintenance with no loose stone, and provides a seamless, natural rustic pathway which looks very much at home in the grounds of London’s historic Royal Botanic Gardens.
The Broad Walk path has re-opened to the public who have already been enjoying the experience. New plants will begin to arrive in autumn 2015 and planting will continue until early summer 2016 to complete the project.
