The Protec system was used to waterproof the domed green roof areas of this sustainable house development on Grand Designs, Channel 4.

With an ambitious vision and a tight budget, Robert and Milla Gaukroger set about transforming an unattractive 1980′s house overlooking Lake Windermere into a state-of-the-art sustainable home.

In order to blend into the hillside setting, the domed roofs of the house were to be covered with a wildflower meadow mix to provide a green roof construction. The Protec System was chosen as a waterproofing membrane for the roofs as it is ideally suited for green roof applications. Lightweight, flexible and highly durable, the system can easily accommodate structural expansion movements and is tough enough to resist root penetration.
