The recent east coast low caused massive erosion at Wamberal Beach on the Central Coast of NSW.
Homes were undermined and large areas of the beach washed out to sea.
Access on the what is left of the beach is very difficult. Options are limited.
Flexibility to deploy an erosion management solution in quick time was important.
The Kyowa rock bags were chosen for their flexibility to be used without the need for site foundation works.
They could be prepared offsite and easily craned onto the beach and still provide protection to the beach face.
The Central Coast Council team were very efficient, filling the bags in under 5 minutes per bag.
They even reduced bag filling time to just over 3 minutes!
The crane operators lifted each bag onto the beach in just under 5 minutes per bag.
Progress was quickly made to prevent further erosion at an average deployment of up to 15 rock bags per hour.
