Pneumatic pipe bursting
for productive pipe renewal

Pipe cracking with Grundocrack

TheGRUNDOCRACK machines are pneumatically driven, modified horizontal rammers, which are applied for steel pipe installation as well as for pipe renewal applyingdynamic bursting. All GRUNDOCRACK machines are equipped with a reverse gear, allowing for the accessories to be disassembled quickly and ergonomically and the machines to be easily recovered, even in confined spaces.

The GRUNDOCRACK pneumatic pipe bursting machines are particularly suitable for renewing damaged pipes made of brittle materials. Applying dynamic bursting, the old pipe is broken open with dynamic impact energy and displaced into the surrounding soil. At the same time, new pipes made of PE-HD (long or short pipes) or PVC-U of the same or larger cross-section are pulled in.
 
In addition to pipe bursting for renewal, the GRUNDOCRACK machines can also be used for further dynamic drilling solutions such as pipe rehabilitation and, with the appropriate accessories, for dynamic steel pipe ramming.

Advantages of Grundocrack pipe bursting machines

  • For trenchless renewal especially of pipe made of brittle materials and pipe rehabilitation 
  • Drive of the pipe bursting machine with compressed air via a standard compressor 
  • Pipe renewal using dynamic pipe cracking allows for new pipes of equal or larger nominal diameter to be installed
  • Pipe bursting means a completely new pipe with a new service life of 80-100 years in the existing pipe path
  • Versatile use for pipe renewal applying dynamic pipe bursting (pipe cracking) and as pile driver for dynamic steel pipe jacking

Application range Grundocrack for pipe bursting

  • Pipe renewal in the  existing pipe path using dynamic pipe bursting, also with cross-section enlargement
  • Pipe rehabilitation using calibre pipe busting also with cross-section reduction
  • Pipe rehabilitation using the Tight-In-Pipe method

Application range Grundocrack for pipe jacking

  • Horizontal application for the construction of underpasses, smaller culverts and pipe screens for tunnel construction
  • Vertical application for foundations and pile driving, well construction, ramming of sheeting walls
  • HDD-Assist & Rescue to support horizontal directional drilling
