Pipe Bursting

Question: What is pipe bursting?

Answer: Pipe Bursting is a technique for replacement of existing pipes. The existing pipe, once burst, becomes the guide path for the new pipe being installed. This technique bursts the old pipe and in so doing displaces the fragmented old pipe into the surrounding soil. This creates a hole of roughly the same dimension as the original. If a larger diameter pipe is to be installed a larger 'expanding cone' is used to increase the size of the hole. Once done, the new pipe is pushed or pulled into position.



This sewer line was 11 feet deep and 180 feet long passing under the swimming pool and a tennis court (not visible in picture). Over a two-day period, this line was replaced using the trenchless method with very little disruption to the landscape, saving thousands of dollars.
