Hydrotech MM6125 Structural Waterproofing and a ZinCo Green Roof system from Alumasc have been used on Belfast Metropolitan College’s new £44m campus. The project recently won Environmental project of the Year at the Sustainable Ireland Awards 2011 and has achieved one of the top BREEAM ratings.
The 20,000 sq m facility, designed by Todd Architects, is set around an inner courtyard and roof garden. Some 4,000 sq m of Hydrotech was installed on the concrete podium of the courtyard which is situated above a basement car park.
Hydrotech is a high performance bituminous rubber blend that provides a seamless waterproofing membrane. Its formulation guarantees lifetime performance and it is manufactured using 10% post-consumer recycled material. Hydrotech is fully warranted, BBA accredited and has European Technical Approval ETA-05/0152.
Landscape architects, Paul Hogarth, specified Hydrotech as part of the green roof package as it can be installed with zero falls, thereby keeping podium height as low as possible. Combined with Hydrogard protection layers and root barriers, Hydrotech offered the ideal waterproofing solution for use beneath Alumasc’s ZinCo Intensive Green Roof.
ZinCo Intensive Green Roof systems enable virtually any type of ‘garden’ landscape to be created and the deep substrate can support a range of plants, trees and shrubs. The college courtyard, where the ZinCo system was installed, offers the benefits of a small urban park, providing a welcome habitat for wildlife as well as additional recreational space for the students.
Main contractor, Patton, approved the use of Hydrotech following a demonstration of its benefits at Alumasc’s headquarters. Roofing contractors on the scheme were Willart Roofing, who received full training from Alumasc to ensure a successful installation.
