Using a pilot bore created by a Grundomat® piercing tool, a Grundocrack® pipe bursting tool can be launched from street level into a manhole, with an absolute minimal amount of surface disruption limited to a small surface patch rather than a full entry pit. Grundowinch® constant-tension winch aids in this process.
Once a burst is complete, a Grundomat piercing tool is used to create a pilot bore from the end-point manhole to street level. The Grundocrack tool is disconnected from the newly installed PE pipe. Using a Grundowinch constant-tension winch as a guide, the Grundocrack pipe bursting tool is removed through the pilot bore with a minimum of disruption to the surface.
