Flaxmill Bay Coastal Protection

Flaxmill Bay is a popular holiday destination located within Mercury Bay on the east coast of New Zealand’s north island.

An existing sea wall that was constructed several years ago needed to be replaced due to coastal erosion of the bank that supported the road network located above it.

The road is vital to the community and a structure was required that could protect the sand dunes on the shore without causing disruption.

The client was looking for a timely and cost-effective solution while reducing the impact on holiday goers to the area during the summer period.

Due to its location, Flaxmill Bay has no natural breakwater and is prone to larger waves breaking onto the beach which undermines the bank supporting the roading network above.

The previous seawall was constructed using incorrect materials which caused the wall to collapse and allowed the erosion of the bank.
