advisable to seek guidance from technical

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 m^2 and

was designed by an architectural

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

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

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.
