Case Study - Proteus Cold Melt® - Battersea Cats & Dogs Home

Battersea Dogs and Cats Home in London, the best-known animal sanctuary in the world, is currently undergoing the biggest development in its 154-year history - a £5 million scheme delivered by main contractor, Sir Robert McAlpine. The development will bring the charity’s existing buildings and facilities into the 21st century and will include a new build, state of the art veterinary hospital which will be protected by an innovative new waterproof membrane – Cold Melt® from Proteus – a seamless application designed to work in harmony with the roof infrastructure and so tough that it has been BBA certified to last for the lifetime of the building.

Quality Control An integral part of this transformation is the built up roofing system of 1,200 square metres of Cold Melt®. Applied by the Proteus Licenced Contractor, a 5 layer built up system was employed to offer a bespoke specification tailored to the client’s needs and budget.

The built up system consisted of a layer of Cold Melt® Proteus’ own innovative, cold-applied liquid membrane, over which an insulation layer of Proteus Pro-Therm XPS was laid. The Licenced Contractor then added a separator sheet of Proteus Low-K followed by an attenuation mat and then three different finishes in three different areas of the roof – paving slabs, a green roof and decking.

Health & Safety Proteus’ liquid applied systems are cold installed and therefore negate all the elements of fire risk when working in confined spaces. Of particular importance was the low odour that Cold Melt® exhibits, meeting all the health and safety criteria necessary to protect both the Licenced Contractor’s operatives and the dogs and cats home’s residents.

Long term performance Cold Melt® incorporates recycled rubber-crumb and other organically grown products and when covered, creates an elastomeric, seamless and cold applied membrane which has a life expectancy longer that the design life of the building on which it is installed.
