The newly opened Pets at Home store at Hedge End Retail
Park, Southampton, provides a striking feature with its clearly visible
barrel vaulted green roof installed by Blackdown Greenroofs.
As well as softening the visual impact of the building, the green roof
helped to satisfy stipulations by BREEAM enhancing the ecological
aspects lost through the construction process.
The impressive 450sqm metre Kalzip, barrel vaulted, standing seam roof was covered with Blackdown
Nature Mat – a vegetated mat made up of 6 core and 13 randomly sown
sedum species – over a system comprising 50mm settled depth of specially
formulated growing medium and a 25mm deep drainage layer.
Because the roof has a maximum pitch of 23 degrees, customised thrust
retention battens were installed to the seam clips at intervals across
the roof in order to stabilise the system.
Further enhancing the biodiversity within the development, a small 10sqm Blackdown extensive wildflower green roof system
was installed on a bike storage facility close to the main building. As
the installation was carried out late spring/early summer, Blackdown
provided a tailored temporary irrigation system to ensure establishment
of the plants into the system.
Blackdown was in contract with T A Colbourne Projects Ltd and
commenting on the collaboration Contracts Manager Tim Bench said:
“Blackdown submitted a competitive and compliant bid on which we were
happy to place an order. The installation went according to a tight
programme with Blackdown working very well with our roof installation
team and completing the works in good time enabling us to strike the
scaffolding and start on the wall cladding. The temporary irrigation
worked very well during what was an extended, very warm and dry period.
We would be very pleased to work with Blackdown again”
