GREEN & BLUE INFRASTRUCTURE
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 .
Beehive Mills back in 2019 , to discuss options for the high-level planters . As a result , the planters were specified with Green-tech ’ s Greentree 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 manmade void former . The intensive lightweight roof soil is around 30 % lighter than standard topsoil ,

To 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 .
Alasdair Innes – Green-tech Specification Advisor comments , “ it ’ s fantastic to see striking building design incorporating greeninfrastructure , in a way that makes it really stand out in the local area . It was a pleasure to be asked to get involved supplying the lightweight soil and other ancillary landscaping materials .”
