The Project

The training centre covering 67 acres comprises eleven football pitches and a 2-storey building, designed to be integral to the environment, houses medical facilities, hydrotherapy/pool areas, educational and media centres, gym, and canteen facilities. The facility not only services the senior and youth teams, but provides services for the local schools, colleges and community. The major challenge of the project is due to it being built on green-belt land just south of the M25, and so limiting its environmental and ecological impact was critical. Amongst other considerations, a green roof was incorporated into the scheme. The roof also needed to be installed quickly so that following trades could proceed internally without hindrance by the weather.

The Solution

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.
