National Concrete Solutions were engaged to extend the service life of 32 existing structural piles and headstock that were to be used in construction of a new concrete decking area that extends out over the boardwalk along Brisbane River.

The piles were suffering from chloride ingress, and corrosion had already initiated. NCS worked with Quakewrap to design a solution of encapsulating the piles from the pile caps, down to the seabed. They installed a 720-degree wrap system that encased the piles and filled the annulus with an underwater grout. The top and bottom of the annulus’s were poured with epoxy grouts, and the top was sealed with a membrane. This process will lock out any further moisture and oxygen ingress, halting corrosion and extending the life of the asset.
