Corfe Hills School worked collaboratively with building surveying firm Kendall Kingscott and Garland UK to secure a £1.9M Condition Improvement Fund (CIF) for critical roof refurbishment works to safeguard the school building’s future.
The existing roofs at the 7,000sqm site had experienced continuous water ingress issues, where multiple roof penetrations from the roof lights leaked, the existing waterproofing system and the overlaid bituminous membrane were failing; resulting in splits and blistering, and the metal roof had rusted beyond repair. With rain seeping directly into the classrooms below, swift action was needed to ensure a safer and more comfortable learning environment for the students and staff.
Garland UK’s Technical Manager, Paul Boole, carried out a thorough investigation of the school’s roof assets for Kendall Kingscott, supporting the CIF bid application. Paul provided the essential core sampling data, detailed condition surveys, U-Value calculations and technical expertise to outline the critical condition of the school and advise the necessary measures to keep their buildings safe and in good working order.
In addition to the roofing refurbishment project, Kendall Kingscott proposed a new-build element to create an enclosed space from an existing rear courtyard. With a diverse set of requirements from new-build to refurbishment in one project, Paul specified a blend of Garland’s high-performance waterproofing systems, including bituminous membrane StressPly Flex, metal trapezoidal R-MER CLAD and Dura-Coat liquid-coating systems.
Utilising a range of systems across one project meant that Corfe Hills could benefit from greater design choice, allowing versatility in the final specification to specify the optimum system that matched the varied building requirements.
Throughout the project, the Garland UK Technical Manager visited the site twice weekly to monitor the progress and quality of the installation, with the Garland UK Approved Contractor, providing regular reports to the School and stakeholders.
The roof system refurbishment saw a drastic improvement to the building’s thermal efficiency, with the new U-Value calculations achieving a 0.18 rating. By reducing the heat loss through the roof, Corfe Hills School can now maintain a comfortable temperature for students and staff while reducing energy costs and overall emissions.
The new-build roof in the courtyard gave a new lease of life to the unused space for the students, creating an inviting area to sit, congregate during breaks and move between classrooms unaffected by weather conditions.
Corfe Hills School were provided with Garland UK’s leading Single-Point Guarantee, offering 20 years of coverage, accepting the total liability for the design, material and quality of the installation workmanship for all three waterproofing systems.
Jeremy Wood at Kendall Kingscott adds, ‘The technical advice and support from Garland UK played an essential part in securing the best waterproofing outcome on this project, utilising three very different systems has meant that there were no restrictions to the roof’s design and we can offer our clients a trusted single-point guarantee that safeguards their building’s future.’
