Kemper System has provided its KEMPEROL® V210 cold liquid-applied waterproofing membrane as part of upgrade works at Huddersfield University.
Recent improvements to facilities include four new buildings, including a new sports hall, Dean’s office and corporate suite, designed by architects Watson Batty. The four buildings have been constructed with a single steel frame and all adjoin each other but rise to different heights varying from 2-4 storeys.
To enhance the biodiversity and aesthetics of the development, green roofs were specified for three sections of the building, including the sports hall, and a warm roof was specified for the corporate suite, in total covering a combined area of 4,500sqm.
While the intention for the buildings had always been to install a combination of green roofs on three of the four roof areas and a traditional warm roof build-up on the fourth, the architect had originally specified a single ply membrane as the waterproofing system for the project. However, having used the KEMPEROL® V210 cold liquid-applied waterproofing membrane from KEMPER SYSTEM for around 30 years, Cawston Roofing suggested to the architect that this would offer a more practical and durable alternative for a similar installed cost as the original specification.
The proposal from Cawston Roofing and ABG was to invert the roof by applying the KEMPEROL® V210 waterproofing membrane first, followed by the insulation, the blue roof drainage reservoir and then the growing medium. The corporate suite section of the building has a metal deck roof and here the roof build up featured a vapour control layer installed directly onto the substrate followed by KEMPERTHERM warm roof insulation.
Nick O’Mara from Cawston Roofing said: "Because the Kemperol waterproofing system bonds seamlessly to any substrate, including verticals, waterproofing of details on the roofs, such as pipe penetrations and drainage outlets was also made quicker and easier, as was the application of the waterproofing system on the upstands. This project really demonstrates how beneficial it can be to consider buildability benefits as well as functionality when specifying a roofing system.”
