Polyroof was chosen to rejuvenate one of Guernsey's most iconic tourist attractions, The Little Chapel.
The Little Chapel in Guernsey was built in 1914 and, at only 16 feet by 9 feet, is said to be "the smallest functioning chapel in Europe, if not the world, and is considered one of, if not Guernsey’s most famous tourist attraction.
The chapel has been undergoing a long term restoration project to create a structurally sound building that retains the beauty of the original vision. Firstly, the foundations were underpinned and properly secured for the first time since they were created over 100 years ago. The next priority was to fix the roof.
With its ability to be applied directly to the concrete to form a lightweight, seamless and durable waterproofing membrane, Polyroof's Protec System was a clear choice for waterproofing the chapel roof.
The first stage was to make the entire roof area fully watertight. Following a coating of primer to seal the porous concrete surface, the first coat of Protec was applied which incorporated fibreglass reinforcement. After 30 minutes the coating had cured and the second coat was applied to the whole roof area. To areas where new mortar was laid to re-embed the pebbles and seashells, which had been painstakingly removed from the old roof, a coating of Polyfinish was applied to provide extra protection.
The architect chose a sanded decorative finish to complement the exterior of the building, which is covered in a mosaic made from seashells, pebbles and broken china. To create this finish a third coat of Protec was applied and, whilst still wet, Quartz Sand was broadcast into the resin. After brushing off the excess sand the whole roof surface was sealed with an application of Polyfinish Clear.
