Kemper System helps Self Builder go Green

Kemper System helps Self Builder go Green

A sustainable contemporary home featuring two green roofs has been constructed with the help of Kemper System.

Located in Surrey, the detached self-build property spans 258 sq m and has been designed by an architectural practice headed by former head of RIBA Jane Duncan. Positioned to make the most of the views, daylight and sunshine, it has been built using a range of natural materials, including timber cladding and Scandinavian bricks.

Homeowner and former builder Nigel Warnes helped to specify Kemper System’s Kemperol V210 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.

He said: “The sedum roofs are a key feature of the house as both are visible to anyone approaching the property. 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 Kemperol was applied by Surrey-based Exterior HomeCare. The liquid resin is installed ‘wet on wet’ in a single process using a reinforcement fleece. Once cured, it forms a seamless and
elastomeric membrane that is inherently root resistant.

As the Kemperol is liquid applied, this also ensured it could be easily and quickly installed around any detailing, including two large roof lights.

On the upper elevation of the property, the contractor installed the Stratex Warm Roof System, which comprises both the Kempertherm tongue and groove insulation board as well as Kemperol liquid waterproofing.

Nigel continued: “With the support of Kemper System’s technical team, Exterior HomeCare was able to install the liquid waterproofing to the highest standard and with no issues. The team also carried out electronic testing prior to the green roof being laid to ensure that the solution was as robust as possible."

“The standard of the workmanship combined with the proven quality of the liquid waterproofing will ensure we can enjoy living in our new home without having to worry about leaks.”

Victoria Ramwell from Kemper System added: “The waterproofing membrane is a vital element of a green roof specification. The use of Kemperol has guaranteed a watertight barrier between the roof substrate and the green roof systems, which 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."
