Freyssinet were engaged to complete repair works to wind turbine foundations at a windfarm in South Australia.

Movement at the base of the wind turbines had been detected and the source of the movement was examined. Upon investigation it was determined that water ingress between the foundation and turbine interface had been exacerbating the movement and creating voids.

Freyssinet’s works involved stabilisation of the turbines through repairs to the foundations and prevention of future water ingress to the foundation-turbine interface.
