The Volute piling technology developed by Collis Civil Engineering saw its first commercial use on December 13 to install a signal post near Peterborough in the UK. The Volute Pile technique is designed to minimise soil displacement, with design loadings based on bearing plate capacity in undisturbed soil. The technique also allows for more rapid installation of lineside structures.
