DESCRIPTION Shotcrete Retaining Wall
A landslip seriously compromised a heavily trafficked section of the Pacific Highway in the Hunter Region. Specialist Site Services was contracted to supply and install permanent ground anchors and reinforced shotcrete to a piled shotcrete retaining wall.
The permanent post tensioned ground anchors were 24 metres long and installed through the piles. Pressure grouting was employed to provide integrity to much of the poor quality ground. Load cells were also installed to facilitate monitoring of the ground anchors during construction and into the future.
Structural shotcrete was applied between the piles, complete with reinforcing mesh and sub surface strip drainage. A final layer of coloured shotcrete was then applied to complete the shotcrete retaining wall project works.
