Prelasti EPDM Roofing
Wirral Churches’ Ark Project is a homeless prevention, support and accommodation service, assisting people with mental health or drug problems, current and exoffenders, former rough sleepers and people who are begging or street drinking. Having started life in 1991 as a temporary shelter operating only for the winter months, a National Lottery Charities grant and local business contributions meant that a new, purpose built facility could be built which became known as Mary Cole House (named after a much-respected member of staff, Mary Cole, Secretary to the Ark). When this building was subsequently considerably extended, AAC Waterproofing were appointed by the main contractor to provide the flat roof covering to the new extension.
Prelasti EPDM sheeting was selected as the waterproofing system for the building due to the rapid installation afforded by the factory prefabricated membrane. Delivered to site in only three separate rolls of made-tomeasure membrane, the roof sheets needed only to be placed in position, unrolled onto Prelasti polyurethane adhesive, and site jointed using a cold vulcanising technique. The custom-made sheets are designed to incorporate excess material for perimeter upstands and details, which are fully bonded to the structure and provided with weatherproof cover flashing details. The rapid speed of installation is of great benefit to main contractors in maintaining their programme schedules and accelerating follow-on trades below the roof level.
