Sliplining of Sandstone Box Culvert Under Rail Tracks, Luna Park, Lavender Bay, NSW

Abstract

Sydney Trains identified that their sandstone culvert at Lavender Bay was in need of urgent repair. Whilst the culvert was in fair condition structurally, there were numerous leaks and a high level of water infiltration as well as significant wall displacement that was catching flow debris. These deformations caused ongoing blockage issues and as a result Sydney Trains were eager to resolve the problem and the risk to their network.
