What was done
Green-tech Specifier was invited to landscape architects Re-form’s offices in Beehive Mills back in 2019, to discuss options for the high-level planters. As a result, the planters were specified with Green-tech’s Green-tree lightweight intensive roof soil, as well as a layer of expanded clay granules to bring up the level in the base, rather than using a heavier sub-soil or some other man-made void former. The intensive lightweight roof soil is around 30% lighter than standard topsoil, and due to the deeper planting of the trees, needs to contain more organic content and hold on to a little more water than the extensive substrate often found on sedum and wildflower green roofs.
A total of 48 cubic metres of lightweight roof soil was used for the 17 Jenga blocks, along with over 4,000 litres of lightweight expanded clay aggregate. This was supplemented on the ground planting with over 400 tonnes of topsoil and subsoil, 2,000 litres of compost and 48 tonnes of pea gravel and decorative silver-grey gravel. The ground level landscaping incorporated a mix of trees in hard and soft, irrigated by a mix of Mona underground capillary tanks and Mona Relief perforated pipes, and supported by Green-tech strap anchors.
The trees in hard were finished off with permeable resin-bound grilles, and for the trees along the front, custom-made grilles, featuring laser-cut Piccadilly East branding and drainage slots. These grilles are made from heavy-duty steel and finished by being hot-dip galvanised, then acid-etched and powder coated in a classic bronze finish, including the normally silver Piazza irrigation inlet. All the steel used in the production of these decorative grilles is recycled by our foundry in West Yorkshire.
The finish off the landscaping, over 200 square metres of Premium Weed Control matting and Ecomatt was supplied along with 2,000 litres of ornamental wood bark for ground cover.
