SIG Design & Technology’s Hydrostop AH-25 product was chosen to refurbish 450m2 of roof at the Sacred Heart Primary School in the Bridgeton area of Glasgow. The project was specified by contractor City Building Glasgow, formerly the building service department of the local authority, as part of a wider refurbishment of the school premises. The school buildings date back to the 1950s. Areas of the roof had been leaking, leading to considerable water damage and disruption to some classrooms.
According to City Building Glasgow assistant investment manager Charlie McLean, the priority for the roof works was to procure a waterproofing system with minimal hot works that would cause as little disruption to the school’s everyday activities as possible. The chosen system would also need to be suitable for installation on a distinctively pyramidal part of the school roof. Another important factor was health and safety, both for those installing the product and the school community.
