Hydrotech MM6125 Structural Waterproofing and a Blackdown Green Roof system from Alumasc have been successfully used on the new £44 million campus of Belfast Metropolitan College. 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 impressive 20,000m2 facility, designed by Todd Architects, is set around an inner courtyard and roof garden. 4,000m2 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 unique 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 Alumascs Blackdown Intensive Green Roof.
Blackdown 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 Blackdown 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.
At Belfast College, Hydrotech impressed main contractor, Patton, who approved its use following a demonstration of its benefits at Alumascs headquarters. Roofing Contractors on the scheme were Willart Roofing, who received full training from Alumasc to ensure a successful installation.
