The flat roof area at above the Guernsey power station had been suffering from water ingress as a result of failings in the existing EPDM membrane. Due to the expensive machinery housed within and the potential for widespread and costly disruption should the leaking continue, Guernsey Electricity turned to Sarnian Roofing Limited, a Polyroof approved contractor, to provide a rapid and effective waterproofing solution.

Works began quickly and involved the removal of the failed roof coverings to expose the concrete deck below. The BBA-approved Protec 20 year system was installed directly to the concrete and rapidly cured to form a long-lasting barrier to water.
