Refurbishment with a new 2 layer Soprasun 3-4 AR Torch on Membrane completed by SRG Global. This system was installed after existing ballast had been moved exposing an old black butyl rubber membrane. The advantage of this the butyl rubber membrane meant that it was conductive of electricity and therefore could remain in place for testing purposes, with only the loose and damaged sections needing removal.

SGR cleaned and prepared each section to the manufacturers specification, cleaning and grinding all perimeter gutter, which would be recoated in Alsan Flashing with mesh reinforcement. Once the membrane was installed and cured, Detec Australia carried out its leak detection service, noting and photographing any breaches for the client's report. All repairs were carried out prior to replacement of drainage cell, insulation board and rock ballast.
