Impact Moling

Impact Moling
Impact Moling is a displacement method suitable for the installation of pipes, ducts and cables up to 150mm in diameter over shorter distances where HDD is either not required or is not feasible/suitable.

This is a traditional method of installing new trenchless pipelines and is performed by pneumatically driven equipment. Diameters from DN25 to DN150 are available. 

Distances: Pipe lengths up to 50 metres. 

Installation rates: Up to 50 metres per day dependent on the required diameter and the ground conditions.

Accuracy: +/- 50mm Ground dependent.

Chiltern Thrust Bore has considerable expertise in Impact Moling services with over 20 years in the field installing pipes for various applications beneath items such as:

  • Domestic installations
  • Roads
  • Various watercourses including major rivers
  • Railways.
  • Runways and taxiways
  • Coastal sea defences
  • Environmentally sensitive areas
  • Embankments/bunds etc...

the list goes on!

Advantages of Impact Moling

  • Dry method of installation – no slurry removal
  • Quick, efficient and therefore economic/cost effective
  • No disruption to the surface infrastructure or services
  • Unaffected by surface obstacles
  • Cost effective and time saving alternative to open cut methods when installing pipes amidst extensive underground infrastructure or at significant depths
  • Small overall footprint for the Works
  • Pipework and cables can be installed in either straight or curved lines to help avoid underground complications
  • Impact Moling requires minimal, or in some cases no excavations due to the equipment that is used
  • Cost effective when compared to more traditional trenching methods
  • A reduced requirement for possessions, road closures, opening notices etc, if required
  • A reduced requirement for restricted working hours
  • A reduced requirement for premium rate working
