The Telstra Tower that overlooks Canberra is synonymous as a landmark and a tourist destination for many Australians when visiting the Nation’s Capital. Since being closed to the public in 2021 during COVID and only maintaining its operational capacity since, Architectus have led the team a team tasked with bringing together the revitalisation of the landmark as both a functional telecommunications tower and tourist attraction for Telstra and the ACT Government.

Waterproofing Integrity were engaged in 2024 for early design works to investigate and report on the state of the 50-year old structure from a waterproofing integrity perspective. Further to this, early concept reviews took place to advise on the feasibility and key considerations in reactivating the podium concourse with a cafe and landscaping to reestablish the site as a tourist and cultural facility. Design works are currently progressing with a builder to be engaged shortly for the site to be made open to the public again in 2027 and once again light up the Canberra sky.

The Brisbane Gallery of Modern Art summer exhibition 2020, Water, featured a range of indoor water themed exhibits.  The artist Olafur Eliasson used 100 tonnes of materials to create the vast indoor landscape of rocks and streaming water named Riverbed, for the first time in the southern hemisphere. 

​

Waterproofing Integrity was contracted to perform Electronic Leak Detection (ELD) and Seam Probe Testing on the Ardex TPO sheet waterproofing.  With the substructure design detailing this waterproofing system as the only line of defence against water escaping into other areas of the gallery, it was critical that a high degree of quality control was implemented.

​

Even the best materials and installation methods can fall victim to damage from a stray screw or dropped tools.  ELD is able to identify micro penetrations through a membrane of coating that may not be easily identified by traditional visual inspections.

The Art Gallery of NSW redevelopment, known as ‘Sydney Modern’ sits in The Domain in Sydney, adjacent to the naval base Garden Island. Waterproofing Integrity has been involved in consultation around the design and application in addition to onsite testing, which included inspecting a waterproofing membrane that had been buried since the 1930s. 

​

Electronic Leak Detection (ELD) was used on the membrane once exposed, which sat above fuel tanks used by the Navy which will become gallery spaces upon the projects completion. Waterproofing Integrity determined that although the membrane being in a good condition given its age, it would still need to be replaced given the damage during excavation. Waterproofing Integrity would return to ensure the new layers of torch-on membrane were continuous prior to concrete pours.
