The Millari pond is a significant indigenous landmark within the Melbourne Museum grounds. The pond is a re-creation of a traditional Aboriginal dreaming site. The pond and landscape area with native flora and fauna is used for the re-creation of Aboriginal ceremonies and is a genuine sacred site. The pond is also used for educational purposes and School excursions. Effectively the pond was leaking significantly into the underground car park, the leaks were so bad the pond had been decommissioned and emptied pending a suitable fix and workaround all the Issues: Pond had to retain natural appearance to support live animals (turtles, yabbies, fish) fauna and flora, the area was a public domain hence strict OH&S issues needed to be observed. The leak was significant to the extent that the exhibit was rendered useless.
Surface preparation followed by WetsuitTM seamless spray on fluid applied tanking was used throughout to solve the leaking issues. Initial cleaning and extensive preparation of all surfaces was required. Native grasses and plant roots had destroyed the existing membrane and fractured the surface hence the existing damaged tanking had to be removed completely. The complete 3 part Wetsuit system including seam sealing was used across the entire pond area of approx. 90 sqm.
Pond leakage fixed completely with successful restoration of the native flora and fauna. Initial works were undertaken to the ‘lower’ pond area; 8 months later, with no leakage and the result proven, the Museum requested further rehab works to the joining and ‘upper’ pond sections, which were suffering from similar leakage issues. The upper area presented another set of unique rehab. issues. The complete pond exhibit is now in full use once again with no loss of native flora or fauna. The PH levels of water were critical to support native aquatic animals such as turtles, yabbies, fish and eels. All components of the pond such as rocks and logs were considered sacred and were carefully repositioned and blessed by the indigenous owners.
