Koombana Drive

As part of the City of Bunbury’s Koombana Foreshore Redevelopment, Ertech was awarded a contract for the redevelopment of Koombana Drive, which included the design and construct of 600m of vinyl sheet pile wall.



J Steel was awarded the contract for the design and supply of the vinyl sheet pile wall and tie rods and the design of the anchor wall and capping.


J Steel’s design team provided the full design package for the anchored vinyl sheet pile wall. A number of different design scenarios were modelled to optimize material and construction costs over the 600m wall length for the differing ground profiles and geometry. J Steel was able to work with Eretech to provide an efficient buildable anchoring system that allowed Koombana Drive to remain open to the public during the duration of the project. The vinyl sheet pile system is a durable, sustainable solution utilizing 90% recycled PVC.
