Where a CCTV survey shows that the pipeline is beyond repair or the system requires the line to be up-sized the client has no option but to replace the pipeline. This can be done by open cut with all the associated costs and disruption or burst the existing pipeline whilst pulling in a new pipe-line in its place.
Pipe bursting is one of the most economical ways to replace a buried pipeline. The direct costs are lower than the traditional costs of dig-and-replace methods, but when pipes are buried under process plants or other services the costs are very low and in some cases the only answer to replacement. When time, disruption and restoration are taken into account pipe bursting is the only logical way for pipe replacement.
With pipe bursting, a wide choice of replacement materials is available. Polyethylene, PVC, glass fiber and many types of metal pipes have all been used successfully.
