This required our installations teams to make repeated visits to site, using both internal and external hoists for access; with work completed in March 2014.”“The inverted roof arrangement means the waterproofing is covered by insulation and either paving, ballast or planted medium,” he added. “Then there is also the sky garden at an angle of 45 degrees planted with trees and shrubs, which will be accessible to clients using the restaurant there.”For public-access terracing across levels 34-38 – as well as a series of applications on the Ground Floor, second floor and the concrete staircase – over 1,200m² of Radmat PermaQuik PQ6100 was applied.
