BUILDING ENVELOPE (ROOFING & CLADDING)
the house as both are visible to anyone approaching the property,” explains Nigel. “As a retired builder, I was keen to be involved in their design, especially the waterproofing to ensure the most effective solution.
“I wanted to use a liquid rather than a single ply membrane as it would fully bond to the substrate offering a more durable solution and greatly eliminating the risk of any leaks.”
The liquid resin was applied by flora and fauna.
Whatever your requirement, it is advisable to seek guidance from technical specialists to ensure your green roof performs correctly, meeting local climatic conditions as well as aspect and biodiversity requirements.
CASE STUDY: LIQUID WATERPROOFING BENEFITS Chapter House is a sustainable contemporary home featuring two green roofs. Located in Surrey, the detached self-build property spans 258 m2 was designed by an architectural
and
practice headed by former head of RIBA Jane Duncan.
Positioned to make the most of the views, daylight and sunshine, the house has been built using a range of natural materials, including timber cladding and Scandinavian bricks.
Homeowner and former builder Nigel Warnes helped to specify a liquid waterproofing resin for the project. The product was required for a sedum roof above the main living area and another above the new garage.
“The sedum roofs are a key feature of
Surrey-based Exterior HomeCare and installed ‘wet on wet’ in a single process using a reinforcement fleece. Once cured, the resin formed a seamless and elastomeric membrane that is inherently root resistant. Prior to laying the green roof, electronic testing was also carried out to ensure the solution was as robust as possible.
The waterproofing membrane, which was a vital element of the green roof specification, has guaranteed a watertight barrier between the roof substrate and the green roof systems, and is also root resistant. Its strength and flexibility provide the homeowner with the assurance that the sedum roof will remain viable for at least 20 years.
