The GRUNDOPIT family

... take your choice

Grundopit is a bore unit which can be combined and applied in many different ways. Depending on the purpose of the bore, pipe diamter, soil type, bore legth and level of difficulty you can chosse among four power classes (Standard, Power and Manhole version).

.... what they have in common:

Practical job site experience has shown that steerable mini bore rigshave to be applied

• when space conditions are restricted,
• when complicated house connections have to be installed but non-steered soil displacement hammers cannot be used due to the terrain
• when a quick, clean, precise and economic solution is required,         
• when open-trenching should be avoided or is actually impossible to use and
• when controlled drilling is required for security reasons.

The main application is the subsequent installation of gas and telecommunication house connections in protection pipes up to OD 63. Parallel installations, street and small inshore water crossings are also possible.

• Depending on the model, Grundopit is started from the pit or outof a manhole
• Depending on the capacity of the machine, the maximum upsizing Ø is 200 mm.
• Depending on the equipment used, Grundopit can also be used in heavy soils with a hammer bore head which is driven by a hydraulic/pneumatic combined power unit.
• Grundopit can work either with a simple water-polymer or a Bentonite suspension, depending on the requirements.

The optimum system for starters is doubtlessly the standard version, which can be upgraded into the power version due to the TT modular system.
