Hall has played a vital role in protecting the Cotton Tree coastline against erosion, having delivered Stage 1 of the Maroochy Groyne Renewal Project on behalf of Sunshine Coast Council.
The scope of works included the removal of the existing geotextile container seawall and two northern groynes as well as construction of two new groyne structures and a 220-metre seawall.
The structures play an important role in protecting community infrastructure such as the nearby surf lifesaving tower, viewing deck, car parks, roads, park and playground from severe erosion.
As part of the project, Hall used purpose-built 5m3 geotextile containers to construct the groynes, increasing the stability of the structures significantly.
In addition to the marine civil works, Hall also used its dredging capabilities to pump 50,000 cubic metres of sand from the lower Maroochy River to Maroochydore beach to assist in upholding the erosion buffer.
