Lake Burley Griffin Wall Renewal Program
Through innovative processes, the NCA is working on the Lake walls to give them at least another 50 years of life. Adam Deutsch from the NCA explains in this video:
The National Capital Authority has recently embarked on a three year lake wall renewal program to repair, strengthen and renew the walls of Lake Burley Griffin to ensure the walls a further 50 years of useful life. Since the filling of the lake in 1963, wind and wave attrition has weakened mortar joints between rocks which has led to loss of soil from behind the walls, stones have dislodged and paving has become loose at the top of some walls. With the help of specialist consultants, the NCA finalised plans and specifications which will inform the remediation work on the formal concrete and stone pitched walls. Repairs and remediation are planned to be finalised late-2021.
