In December of 2014 we were approached by Fulton Hogan to rectify a fault in a newly installed gravity sewer main in Karaka.
The pipe had sunk in soft material well below its tollerance level for several meters upstream and downstream from a man hole. Because of the depth of the pipe, open trenching the pipe would have been very expensive and time consuming operationally. We were asked if we could find a cost effective and time efficient way to level the pipe without the need for open excavation.
We arrived on site in January 2015 to implement our solution. Within two weeks we had successfully levelled the pipe for a fraction of the price it would have cost to open trench the site, and in a shorter time frame. This was the first time anything like this had been done, which created huge interest from many people who watched the project and its result very closely.
