Flagon PVC and Green Roof for Strathmore Centre

The Strathmore Centre is an important educational facility in Teddington, West London. Soprema supplied the roofing products for this new building, working closely with single-ply specialist Rock Roofing, main contractor LIFE Build Solutions and green roof partner SkyGarden to achieve a stunning result. Steve Hatcher, Contracts Manager at Rock Roofing, greatly appreciates the reassurance that, “once you’ve installed a Soprema product, you know you have delivered top quality.”

SOPREMA FLAGON PVC

The roof build-up for the Strathmore Centre project consisted of a FLAGON PVC single ply membrane with a Wildflower Blanket System from SkyGarden on top. Steve points out that, especially in this kind of scenario, the reliability of the waterproofing is key: “Soprema’s single-ply is not only easy and quick to install, it is also highly reputable. When installing a product beneath a green roof, you need to have the confidence that that product will work. That’s the reason we choose to partner with Soprema.”

CLOSE COLLABORATION ON THE DESIGN

Rock Roofing, LIFE Build, SkyGarden and Soprema collaborated closely on some last minute changes to the specification and the design.

INSTALLATION TYPE

Originally, the team at Rock Roofing had proposed a mechanically fixed roof system. Yet on-site checks revealed that a loose-laid system would be a better match for the concrete beam construction of roof. Moreover, the latter installation method would be quicker.

Steve and his team checked with Soprema to ensure that the proposed change would be covered by the guarantee, and with SkyGarden to ensure that the green roof met the minimum weight requirements. “Once we got confirmation from all the parties involved, we moved forward with the new installation type”, Steve explains. “We always get good technical back-up from Soprema, making for a very easy process, even when lastminute adaptations are required.”

PARAPET CAPPING

Moreover, Rock Roofing came up with a value-engineered alternative for the capping on the parapets that were supposed to be done by a third party. Steve: “We gave the main contractor an alternative parapet detail, which would speed up installation and result in significant cost savings. We proposed a smaller capping and consulted with the team at Soprema to make sure the new perimeter detail was in agreement with them, which it was.” Thus, Rock Roofing saved LIFE Build considerable time and money.

A BEAUTIFUL GREEN ROOF

Steve looks back with satisfaction. “We had no complications or issues and even won back some of the lost time”, he recaps. LIFE Build is very pleased with the result as well. Steve: “We got some great feedback from them. Even though they think the green roof looks amazing, they pointed out that, in a way it’s a shame it covers such a nice roof. That’s a beautiful compliment.”
