Kingscliff Foreshore Revitalisation – Stage 1 Seawall

Due to exposure to an extremely aggressive marine environment, engineers specified concrete to be of low permeability to chloride ion penetration to reduce the risk of corrosion to embedded reinforcement. As part of the performance spec, the majority of marine grade concrete, including precast elements to be cast below the waterline, were treated with Xypex's High Performance Admix Solutions to significantly enhance the durability and extend the service life of this high-profile structure.

Specialist consultation was provided by Xypex Australia's Technical Department, with a view to provide significant extension of life of the asset for the Council considering the aggressive marine tidal/splash zone exposure. Our aim was to provide a solution that significantly mitigated ongoing maintenance costs. A whole of life approach was adopted, with a view to provide a robust system without extensive ongoing maintenance. Our high-performance Permeability Reducing Admixtures were welcome here, as they removed the construction timeline delays, risks associated with human application error and the significant application cost associated with physical barrier systems that are often adopted in these environments.

A Port Authority, were engaged by a lithium processing business to commence the holding of Spodumene, an important source of Lithium for mobile phones, automotive batteries etc.

The shed that was available didn't have a sound concrete base slab within it which was a requirement of the client as they would need to run loaders in and out for the handling process. Although spodumene is a non-toxic powder once broken down, the EPA were looking for a long-lasting, maintenance-free, durable option that would give flexibility to house several different items should they need to in the future.

Xypex Australia put forward the use of Xypex C-5000 Admix which would offer all the protection requirements they'd need now and for the life of the concrete, which was backed by independent test reports and data. Based on the provided reports and data, the client then proposed a reduction of the original design slab thickness. This was approved by the Port and by doing this it became a very cost-effective way of delivering a very durable slab. Xypex C-5000 was specified into 17,500 m2 of concrete and will now be the first option for future slabs at the port.
