  • GREENGRID MODULAR GREEN ROOF SYSTEMALBERT HOUSE, WESTON-SUPER-MARE Albert House Nursing Home is situated in Weston-Super-Mare just metres from the sea. The existing building is being renovated and as part of his remit to ensure the best possible environment for his clients, the owner wanted to install a new green roof. Further new build works to the development will also have a green roof. After looking at various systems, the owner identified the GreenGrid system as being the ideal choice for his requirements, since it meant that he could have easy access to his existing older bitumen roof surface at any time and he could incorporate new GreenGrid areas onto his new buildings as each stage of the development progressed. For the initial GreenGrid phase on the existing roof, the modules arrived on site at 10.30am, delivered by HIAB truck. The modules were hoisted onto the roof in protective wrapped cages where they were easily removed in preparation for laying. Since the GreenGrid modules are completely self contained green roof units, this meant that there were no complicated staged material deliveries to co-ordinate. For this project, there was one vehicle, a minimal period of time to hoist and installation began immediately. A protective layer of geotextile fleece was laid over the existing bitumen waterproofed surface. This protects not only the waterproofing, but also the GreenGrid modules themselves, as some membrane types, for example PVC, have been known to cause cross contamination with other materials. Once the fleece was loose laid on the surface, the modules were simply carried to the required location and laid onto the fleece in accordance with a module layout plan which was provided by Trelleborg.

  • GREENGRID MODULAR GREEN ROOF SYSTEMALBERT HOUSE, WESTON-SUPER-MARE GreenGrid is a simple system to install and large areas can be covered in a short space of time. The flexibility of the system meant that the client had freedom to choose his level of maintenance, the design and the budget. Should a decision be made at any time to change the plants, the design or the area of the roof covered, this is easily achieved. On this occasion, the project was completed at 1.15pm, which meant that the time taken from arrival on site to departure was just under 3 hours. This ensured that there was little or no disturbance caused to the nursing home residents. Once the modules were placed, the client had an instant green roof. GreenGrid modules are grown and matured in the nursery prior to delivery, which means that an established effect is provided immediately, as can be seen here. The planting is deep and lush and some sedum modules are even in flower. The 100mm depth of growing media ensures that the sedum has enough sustenance to encourage it to grow and thrive for many years to come. Other green roof systems can take up to two years to become established and much greater maintenance and supervision is often required. Although the modules were initially visible, after a few weeks the sedum merged together to form a complete carpet, and the client still has complete peace of mind knowing that he can still reach his waterproofing layer easily. Should his waterproofing eventually need replaced, he can still retain his green investment by moving the modules off-site, renewing the waterproofing and then returning the GreenGrid modules back to their location.
