Background
Following a severe weather event in July 2024, there was a landslide on Mount Dandenong Tourist Road near Mason Grove in Sassafras.
Our first priority was to stabilise the landslide, cap and redivert an existing gas main service, and clear as much debris from the roadside as possible to ensure the road was safe to reopen.
Once those works were completed, our geotechnical experts completed a range of detailed design investigations including geotechnical, hydrological, underground services, pavement and visual inspections to inform the detailed design.
The site was further complicated by multiple underground utilities, steep drop-offs, its close proximity to the Sassafras Creek and road width.
Considering the damage caused to this section of the road, major retaining wall works were required to properly repair the landslide and safely reinstate the road to a two-lane road.
