Stretching 1.8 kilometres across Geographe Bay, Busselton Jetty is the longest timber-piled jetty in the Southern Hemisphere. It is appreciated for its spectacular Underwater Observatory, Jetty Train and myriad of recreational uses.
In May 2009, Marine and Civil Construction Company Pty Ltd was awarded the $27.1 million refurbishment contract. The refurbishment included
1. The complete replacement of approximately 50% of the 1.8km long existing jetty structure. This entailed demolition of approximately 900m of the existing jetty;
2. Temporary dismantling for substantial repairs to the remaining 50%;
3. Driving of approximately 200 new timber piles and 108 steel piles, predominantly for the new 900m section;
4. Reconstruction of various parts with timber decking for their heritage values;
5. Refurbishment of the small 'Scout Road Jetty' located 100m east of the main Busselton Jetty.
Xypex C-Series Admix was specified for all concretes used in the refurbishment, as all encompassing protection for ‘concrete used in a marine environment’.
