THE NEW GENERATION
Grundomat soil displacement hammers

Trenchless pipe installation with impact moles

The pneumatically driven impact moles work according to the soil displacement method. Unlike steerable horizontal boring machines, the non-steerable mole hammer compacts the spoil into the surrounding soil when moving forward. Thus a channel is produced, into which short pipes with smooth sockets, or long pipes made of plastic (PE, PVC or PE-X) up to OD 160 or cables are pulled in. Depending on the type of soil, lengths up to 25 m can be either pulled in directly or later on. For operation, a compressor with 6 - 7 bar operating pressure is required. That way, crossings underneath valuable surfaces and house service connections can be established with the mole hammers in a cost-effective and environmentally friendly manner.
 
The optimised design of the new GRUNDOMAT impact moles features new technical solutions, which further improve durability and minimise time and service effort for trenchless pipe installation. The variety of applications with the mole hammer is also retained and new options, such as servo- control for small machine sizes, simplify handling.

Working principle of the Grundomat impact mole 

The GRUNDOMAT soil displacement hammer’s high target accuracy is due to the 2-stroke principle. With this proven concept, the piston initially strikes the chisel, which advances forward in order to produce the bore hole and to destroy any obstacles along the way. The casing is impacted in the second stroke and pulled in with the pipe attached. That way peak resistance and casing friction are separated and alternately easier to overcome. This makes the GRUNDOMAT mole hammer work dead on target even in stony grounds.

Advantages of impact moling with Grundomat 

  • High penetrating power and reliable thrust
  • On-target pipe installation in 2-stroke principle thanks to movable head
  • With crowned or step head for pipe installation even in difficult soils 
  • For house connections and undercrossings up to 25 m in length
  • Durable, low-maintenance technology 'Made in Germany'
  • Flexible and versatile application range

APPLICATION RANGE Grundomat impact moles 

  • House connections:
    Fast, safe and economical construction of house connections for fibre optics (FTTH), gas, water without trenches directly into or out of the building 
  • Undercrossings
    When crossing underneath roads, railway tracks, gardens, buildings and other valuable surfaces, the GRUNDOMAT impact mole is unbeatably fast, accurate and reliable
  • Pile foundations:
    When used vertically, foundations, e.g. to set piles or signs, can be created easily and safely with the GRUNDOMAT mole hammers               

SPECIAL APPLICATIONS Grundomat impact moles

  • Pipe ramming (from type 130 on)
    for driving steel pipes by attaching different ram cones
  • Pipe renewal (from type 130 on)
    with modified mole hammers using dynamic pipe cracking
  • Extraction of steel pipes 
    with attachment mandrel for simultaneous pulling-in of new pipes
