Weatherproofing Advisors Limited were instructed, by Savills Plc, to carry out the roof replacement project to an office block in the centre of Uxbridge.
The project consisted of removal and replacement of the existing inverted flat roof covering. The new waterproofing system consisted of a vapour control layer, tapered insulation system to meet current Building Regulations, and IKO Mach One mineral felt.
The roof covering provides the client with a 25 year material and workmanship guarantee.
The nine storey, fully glazed high level building offered numerous challenges, in particular the vast amount of HVAC equipment that remained in situ throughout the project.
WPA had to develop a system that enabled the waterproofing system to be installed, while at the same time ensure that the building remained fully operational and without disruption.
Each HVAC unit was independently supported during the works, with a ‘Big Foot’ support system retrospectively installed once the new waterproofing was in place.
