Challenge

Korere drive in stonefield area of Auckland is a hilly area with weathered rock strata. Due to the weathered strata, it has surficial instability issues which leads to boulders/debris detachment from the slope frequently. And hence hinders the traffic. A permanent solution was required for this problem.

Solution

After the due diligence, Maccaferri high resistance steel wire mesh, steelgrid HR50 with polymeric coating was selected for secured drapery system. A geocomposite mesh- SteelgridHR50_P with ropes inserted into DT mesh with high tensile strength, high stiffness, greater density and superior coating for long durability has been chosen for the project. Erosion control matting is used below the mesh at selected upper zones of the scoria mixture regions. The work started in Q3 2024. At present the construction is going on, and the project is expected to be completed soon.
