Sutherland Shire Council, south of Sydney, used the Rocla PermaTrak® concrete boardwalk system to enhance an urban park at Caringbah.
The PermaTrak® system was originally specified to minimise damage to exposed tree roots. Existing mature trees provided a pleasant shaded area, but were in danger of root damage from a conventional concrete pavement.
The steel-reinforced concrete treads and bearers of the PermaTrak® boardwalk system are supported on small concrete stumps that can be spaced at two or three-metre intervals to suit site restrictions.
The council’s own construction contractors assembled the system. Although it was the first time they had used the system, the installation went smoothly.
Mike Walker, the council landscape architect, designed the installation. “Although we specified the system as a practical solution,” Mike said, “there was also an aesthetic reason, as the boardwalk enhances the park environment.” Seating platforms were also created, branching from the sides of the boardwalk, to provide an opportunity for passers-by to sit in the shade of the trees and, eventually, appreciate the garden beds planted beside the pathway.
