Corfe Hills School, 3 system waterproofing scheme

Established in 1976, Corfe Hills School in Dorset welcomes over 800 secondary and sixth form students through their gates each year. Since achieving Academy status in 2011, Corfe Hills have been looking ahead, keen to develop a schedule of works for building improvements that support the school’s growth and ultimately safeguard the building’s future.

Over time, the existing roofs across the site had experienced continuous water ingress issues that needed to be addressed. Multiple roof penetrations from the roof lights were leaking water; the existing waterproofing system and the overlaid bituminous membrane were failing in places resulting in splits and blistering, and the metal roof had rusted beyond repair. With rain seeping directly into the classrooms below, action had to be taken to ensure the site was remedied to a safe and comfortable learning environment for students and staff.

Garland Technical Manager, Paul Boole, was instructed by building surveying firm Kendall Kingscott to support Corfe Hills approaching CIF bid for the critical roof refurbishment works. An essential part of the brief was to ensure that the buildings were not only fully waterproofed but to upgrade the overall thermal efficiency, alongside securing a robust 20-year guarantee.

In support of the CIF bid, Paul carried out a thorough investigation of the school’s roof assets for Kendall Kingscott, producing core sampling data, detailed condition surveys and U-Value calculations to outline a clear specification for the works required.
