HD is proud to be involved in an important jet grouting project in Sydney, Australia. 2 units of HD202 hydraulic drill rigs are currently doing jet grouting there, for column diameter 2.2 m, 6 – 8 m height, at around 25 m deep. This is for ground consolidation in a highway construction project. The highway network is currently being extended in Sydney, as the city is being built up.

The M6 Stage 1 Project (previously referred to as the F6 Extension - Stage 1) received planning approval from the Department of Planning, Industry and Environment. The project is a key element of the NSW Government's transport vision for NSW, connecting Sydney’s south to the wider motorway network.
