Wollongong, NSW

The penthouse units were causing leaks into the units below and the rooftop above the penthouse units were causing leaks into the penthouses. The tender included a few options for the committee to choose from including tiled balconies or exposed membrane, and rooftop waterproofing options. This allowed the committee to review the cost of these options and complete the works in a way that best met the committees requirements. Committee meetings with engineering consultation were also conducted to understand the committee needs and therefore most suitable option for this building. This allowed the committee to proceed with the cheaper option for the penthouse balconies but the best (more expensive membrane) option for the rooftops. This adjustment allowed the committee to understand their priorities and execute the project to best meet the requirements and future planning goals for the building.
The project itself required challenging waterproofing detailing to meet the construction detailing of this old 1960s building. The internal channel drains within the rooftop required special sections manufactured to suite the building and integrate with the waterproofing system – this further highlights the importance of choosing the right material for each project.
