Sky Garden have recently installed this stunning 700sqm intensive podium green roof system in Liverpool.
A combination of concrete paving, kerbs, benches, plants and turf areas had to come together to create a beautiful space for local residents to enjoy that would otherwise be wasted if a standard roof had been installed.
The sub layers for this project were crucial. The root barrier and protection fleece were installed to protect the waterproof membrane below. The 40mm drainage board across the entire roof area was filled with crushed gravel in order for the permeable paving above to drain quickly and effectively.
The intensive substrate, plant species and turf were carefully selected to endure roof conditions. Shade tolerant and low maintenance vegetation was essential on this project to keep the roof looking great all year round.
Due to the irregularly angled design of the roof, our installation team worked tirelessly to execute a clean, professional finish on time, to budget and with minimal material wastage.
The heavy concrete benches and kerbs were craned skilfully into place in order to avoid having to move them once landed on the roof. This avoided potential damage to the roof and risk to our installation team.
The key issue that Sky Garden overcame on this project was the potential risk of damaging the inspection boxes with the spider crane being used on the roof. It was feared that the initial design of the boxes could give way to the weight of the crane legs. Using initiative, Sky Garden delighted the client by designing an inspection box that could withstand the loading weight of the crane and therefore avoiding any potential roof damage or injury.
Although this Liverpool project was not a usual extensive green roof system that we are used to installing on a daily basis, Sky Garden leapt at the opportunity and created a beautiful, eye-catching podium roof which since has opened doors to similar projects.
