A ‘Living wall’ erosion control solution has been installed at the Kuratau River mouth. The grassed wall provides a robust edge to the grassed reserve and is a more natural solution than hard structures like concrete.
Mesh ‘socks’ are placed over a compacted pumice base, which in turn is overlaid with a geotextile cloth designed to contain the pumice material behind the wall while still allowing water to pass through. The upper three tiers are filled with a soil/grass mix, the lower three tiers are filled with a scoria mix.
The system has been used on other lake shores around the world with great success, so we are hopeful that it will withstand the wave action that Taupō can generate during severe weather events.
