SYNOPSIS

Managing groundwater in underground construction remains a persistent challenge for engineers. Water ingress and the resulting hydrostatic pressure can cause long-term damage to tunnel linings and retaining structures, leading to deterioration, corrosion, and costly maintenance. Methods of managing water pressure is a difficult discipline and soil conditions can be uncertain and risky, both during construction and over the lifetime of the structure.
The webinar explores an approach to addressing water pressure in underground structures using a systematic, continuous drainage approach, integrated in monolithic shotcrete layers. The design enables water to be redirected before it accumulates behind the lining, helping drastically reduce construction time, cost and CO2 consumption and maintain structural integrity over time. The webinar will present examples of how this approach can be applied in different construction methods.
