CASE STUDY: Kew Royal Botanic Gardens

Addagrip are delighted to have been involved in the new Broad Walk project at the Royal Botanic Gardens, Kew having just completed an installation of over 3000sqm of our innovative new porous paving system, Terrabase Rustic, carried out by approved contractor, True Grip Ltd.

The new project will create the longest double herbaceous borders in the UK. The 300m long borders either side of the Broad Walk from the Orangery to the Palm House Pond, will be planted with swathes of 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 and could 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 maximum 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 the 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.



  • St Georges Hill 1
  • St Georges Hill 2
  • St Georges Hill 3

CASE STUDY: Sports Complex, St Georges Hill

Addagrip approved contractor True Grip Ltd was asked to provide a surfacing solution for the grounds of a private sports complex in St George’s Hill, Surrey. The requirement was for a hard wearing, attractive but natural looking surface for the sports complex’s paths and adjoining access roads. True Grip put forward Addagrip’s innovative new surfacing system, Terrabase Rustic, which provides a rustic looking, porous paving that can be installed without the need for an asphalt or concrete base.

A total of 1,000m2 of Terrabase Rustic Gold was installed in two phases. The footpaths were a challenging installation due to the severe gradients and distances around the site. The Terrabase Rustic for these footpaths was laid directly onto an MOT sub base to the new site and directly onto a self-binding loose gravel to the paths to the existing house. To accommodate the relaying of a tennis court surface, the newly installed Terrabase Rustic had to withstand 2 ton dumper vehicle traffic whilst the work on the court was completed.

The 1,000sqm installation was finished on time with minimum disruption, despite the poor summer weather.

As part of the design, Sarah specified a resin bound Terrabase Rustic surfacing for the pathway and courtyard area.

Addagrip approved contractor True Grip, who installed the surfacing, was able to negotiate the intricacies of the layout to install the beautiful Terrabase Rustic bound paving in a Rustic Tweed blend. The larger 6-10mm stone size provides a very natural looking porous surfacing finish which is comfortable underfoot and aesthetically pleasing. It is low maintenance, requiring no sweeping and can be power washed if required to keep it looking pristine.
