SIG Design & Technology’s expertise in providing effective roofing solutions for listed buildings was invaluable for one of London’s first skyscrapers.
Standing 117 metres above the streets of the West End, Centre Point’s Tower is an unmissable landmark - the Grade II listed 34 storey structure cuts an impressive architectural figure. It’s part of a wider complex which is used for retail and residential purposes.
The Centre Point building comprises of a number of parts in addition to the iconic tower. SIG D&T brought its technical expertise at the base of the tower. SIG Design & Technology’s proven capabilities in providing effective roofing solutions for listed buildings meant their specification expertise was invaluable in meeting the various challenges.
The refurbishment project saw eight separate areas at Centre Point being waterproofing to SIG D&T’s design specification. To the iconic tower itself, the aesthetic requirement from the architect and client stated that no waterproofing on the terrace areas should be visible.
Having a waterproofing solution that could detail at interfaces and upstands with liquid and tight detail that was both compatible with the existing design and offered a guaranteed solution was also critical. Working with specialist sub-contractors. AC PLC, SIG advised on waterproofing for the window façades in part of the tower.
At Centre Point Tower, existing asphalt had cracked and failed over the years, allowing for unwelcome water ingress. Water was leaking into the existing buildings down to the ground floor level and caused problems during the strip-out of the existing ground floor. Water attenuation had become an issue, as the waste pipes had not been upgraded in recent years. SIG Design & Technology specified a build-up which will contribute to a sustainable urban drainage system (SUDS) including two green roofs, in order to slow down the release of surface water run-off.
In total, the refurbishment project saw eight separate areas at Centre Point being waterproofed to SIG D&T’s design specification.
