Duratec was engaged by Curtin University to perform repair works to building 201 which was constructed in 1967.


The building consists of 7 levels with a terracotta tiled roof laid on timber battens. Level 7 ceiling comprises a fibrous plaster glass ceiling with a sprayed vermiculite finish. Air conditioning units are mounted on the roof.

The roof had deteriorated significantly over time as a consequence of poor construction and ambient factors. Historical roof leaks were occurring on regular basis due to cracked/damaged roof tiles, improper sarking installation, failed sarking joint and cracks in the copper gutters. The scope included:

Internal repair works:

  • Removal of existing ceiling finish.
  • Repair of defects.
  • Installation of new screws and timber battens.
  • Application of vermiculite gypsum.
  • Application of acrylic sealer undercoat.
  • Application of 2 coats of paint.
  • Installation of light fittings.

External/leak rectification works:

  • Installation of anti-ponding boards.
  • Sarking repairs.
  • Service relocations.
  • Copper gutter waterproofing.
  • Tile replacement.
  • Replacement and installation of 9 new roof mounted air conditioning units.


  • Works were completed on a tight time frame during the university’s Christmas break to allow the building to open for the new semester.
  • A 300 tonne crane was mobilised to install the air conditioning units.
  • All works were completed to the client’s satisfaction and were injury free
