The specification 

The brief for the project was to renovate the graduate centre and to link to the main college by creating a new entrance to the building. This led to the construction of a new building, the McCall MacBain Graduate Centre, which also now provides access to the Barbara Naylor rooftop gardens above the different reading, media and seminar rooms of the graduate centre. With the ageing existing waterproofing exceeding its life expectancy, the roof garden terrace was in need of a replacement roof system.

As an accessible area which will experience a significant amount of foot traffic, the Bauder Hot Melt was determined to be the best solution for this roof. With a durability to match the expected life of the building and a self-healing system, the Bauder Bakor Hot Melt System is ideal for use on protected roofs such as inverted, paved, ballasted and terrace roofs.

Products applied

Bakor 790-11:
Hot applied, rubberised bitumen formulated to provide a monolithic fully bonded roofing and waterproofing membrane.

The result

Approved contractor Deane Roofing & Cladding carefully removed 439m² of the existing waterproofing, stripping the rooftop back to the concrete deck surface before installing the different layers of the Hot Melt system.

The completed roof terrace now provides a modern and peaceful garden area where graduate students can relax and socialise between their work periods. Following several site visits by Bauder’s expert Site Technicians and a final leak test, a 20 year guarantee was issued for the roof terrace.
