Before works could begin, temporary pollution control measures were required to avoid any foreign bodies entering the watercourse whilst the works took place.
This included the installation of a silt curtain to control the dispersion of any mud and dirt. As a precaution, an oil boom was also used downstream of the works to ensure any fuel spillages would be contained.
A CAT scan of the area was conducted prior to the excavation of a 3m trench and the installation of support stakes along the river and bankside. Rock rolls were then laid horizontally and securely tied to each other and the hardwood stakes, ensuring a sufficient hold.
Drainage shelves and trenches were dug into the bank and filled with stone to create a constant gradient that will allow the bank to drain during a flood event and protect the surrounding areas.
Once fully installed, soil was layered over the rock rolls followed by a coir roll matting to provide further stabilisation to the bank and prevent future soil erosion.
A final layer of top soil was used to cover the matting and grass seed was distributed across the bank and surround areas.
