Picton Projects Perfect Pivot

Earlier this month, our crews were presented with the challenge of providing a temporary solution for two gas-attacked and eroded concrete maintenance holes that were identified by Sydney Water.
Due to the location, our crew had to adapt and overcome some challenges. The project was near a creek that regularly flooded and, which a week prior had inundated the project site to be one meter under water.
No entry was allowed into the maintenance holes until the structure was supported, as they were not considered structurally stable. This ruled out traditional repair methods including internal support or bracing. The project also required a double pump station shutdown, meaning short working windows for our crews.
Our solution was to utilise our Expanda lining system and winding it vertically to create an internal support structure for the maintenance hole. This bought the client time to develop a methodology for rebuilding the maintenance holes.
Well done to the team for overcoming the elements and finding ways to solve our customer’s problems.
