Tottenham Hotspur Training Ground - Green Roofing

The Contractor specified Profiles Vapour Vent-XL as the vapour control layer. This was installed first, so that it would function as a temporary waterproof layer. This played an important role during a spell of heavy rain. There were a number of more complex detailing, such as in areas where the large curved beams of the glazed roof met the main building, and these were detailed with great diligence by McCormick’s installers. Once the waterproofing was laid, an Icopal extensive green roof system was installed. First to go down was an Icopal SLP300 Protection Fleece to protect the waterproofing membrane beneath. The Fytonop 20 drainage board followed, overlaid with the Icopal Filter Layer to contain any fines from blocking the drainage system. Icopal Extensive Sedum substrate was installed and raked level, and then finally the planting; Icopal Extensive Sedum Mat, which is rolled out over the substrate. The area of the green roof was surrounded with pebble borders, and restraint angles to create a defined edge.
