The Problem


Cameron House is a 5 Star Luxury Hotel set on the iconic banks of Loch Lomond in Scotland. The hotel offers a variety of dining experiences, including the Michelin starred restaurant Martin Wishart at Loch Lomond. When the flat roof areas above the main kitchen and the dining area began to leak, it was imperative that a rapid waterproofing solution could be found that could be installed without disturbing operations at the restaurants below.

The roof area itself was covered with an aged felt membrane that had been treated with a variety of localised repairs which could no longer prevent water ingress. A large amount of M & E plant was present throughout the roof, and any new waterproofing system would be required to seal the numerous stanchions and plinths in a fully weatherproof condition.

After researching waterproofing systems online, Cameron House Hotel contacted Polyroof Technical Services for a recommended waterproofing solution that met their stringent criteria. Following discussions, the regional technical manager carried out a detailed roof survey of the roofs. The survey report formed the basis of a bespoke specification that covered a comprehensive set of recommendations to fully solve the roof's problems.

The Solution


Polyroof approved contractor Skyform Roofing successfully tendered the project and the refurbishment works soon began. In order to avoid disruption to the hotel's operations the existing roof coverings were retained as a substrate for the Protec system, without the need for stripping / replacement works. Due to the complex nature of the roof, works were carried out within a phased approach with the most problematic regions being refurbished first. Loose-laid M & E plant was relocated and the felt coverings cleaned and made good as required. The remaining roof details were then prepared as necessary before being primed ready to accept Polyroof's cold liquid-applied Protec system.

A key advantage of the Protec system for phased refurbishments is its speed of application and rapid curing. Unlike moisture-curing liquid systems, Protec forms a solid, extra-tough membrane that can be walked on 30 - 60 minutes after application. Not only does this reduce labour times and keep costs down, but crucially it allows the full system to be laid in it's entirety in a matter of hours - rather than days.

With its fibreglass reinforcement, the Protec resin is able to rapidly mould around any protrusion, stanchion, plinth or upstand to quickly form a totally seamless watertight seal - without the need for any time consuming cutting or patching work. This meant that the many complex roof details were able to be rapidly made waterproof, further reducing installation times.


The contract monitoring undertaken by Polyroof Technical Services allowed the contractor and manufacturer to work effectively together to ensure the roofing solution delivered on all the client's needs. The application by Skyform Roofing was completed to a very high standard with every roof detail meticulously sealed in a fully weatherproof condition.
