Sydney, Australia
The landmark residence located in the Sydney suburb of Forest Lodge, is a 3.9-meter wide, two-story home built on the principles of sustainability. The house features advanced insulation, water conservation and a unique green roof, that collects and stores stormwater, providing a reliable water supply. The Forest Lodge is Australia’s most awarded house, having received 13 national and international design and construction awards with the most recent award being the HIA GreenSmart Home of the Year, which recognizes the best in environmentally responsible housing across Australia.
Project Requirements
To protect the building structure from the damp environment of the green roof, the owners sought a reliable waterproofing membrane which is durable, root resistant and long-lasting. According to the owner Chris, due to a high risk of water ingress, it was important to avoid compromising on the waterproofing solution as it could potentially impact longterm performance and durability. Having used Sika products for sustainable construction projects in Europe, Chris selected Sarnafil® for his project.
Sika Solutions
The owner Chris Knierim specified a 1.5 mm thick Sarnafil® G410-15L felt membrane for the project. The waterproofing membrane was fully adhered with Sarnacol® 2142S to prevent leaks and water ingress under the membrane, should the membrane be breached with punctures or damage being root resistant, Sarnafil® is ideal for green roof applications from small residential projects to large scale commercial builds. With the inability of roots to penetrate the membrane, the risk of water ingress is reduced.
