Wednesday, 17 February 2021
6:00 PM - 9:00 PM


Kirribilli Club
11 Harbourview Crescent , Lavender Bay NSW 2060


Please note in 2021 NSW seminars commence at 6pm.

This seminar will focus on the invisible frontier of concrete piling and foundations together with the difficulty of placing concrete underground. Recent piling works at Wamberal on the Central Coast will be discussed. During July 2020, there was a large amount of coastal erosion in the area and a number of residential homes suffered damage.

In addition, this event will focus on the challenges associated with placing concrete underground within a complex reinforcement cage. Following the presentations, there will be an opportunity to network and socialise while enjoying a drink and something to eat at the Kirribilli Club. We look forward to seeing you all on the night.
