Using geotextile sandbags for erosion control

The Basin campground in Ku-ring-gai Chase National Park is one of Sydney's most popular beach camping spots.

But after an existing rock wall was destroyed in the 2016 east coast low, erosion began to threaten campground assets and the local big Northfolk pines.

Our specialist Soil Conservation Service team was engaged to remove the damaged rock wall and build a modern geotextile sandbag structure to replace it.

The large geotextile sandbags allow the waves to dissipate their energy by sliding up the beach, instead of crashing into the rock wall. They also add amenity to the beach and mean a safer environment for visiting families.

Tides and the close proximity to the public presented challenges, but at the end of the day, our staff got the job done and kept safety as our number one priority.
