Impact Moling is a pipe or duct installation / replacement technique in which a pneumatic piercing tool, the Mole, is used to create a bore hole between two particular points. Typically a pit is dug at the start and finish points and the mole progresses horizontally between these points without surface disruption. The ground is compacted and displaced by the mole rather than excavated and removed .
This technique, also known as trenchless technology, is often favoured to install services such as:- Water pipes, Electric cables, Telephone ducting, Gas pipes, Drain & Sewer pipes and Ducts up to 150mm. Its non surface disruptive nature makes it very suited to go under Roads, Drives, Lawns, Buildings & Rough Terrain.

Pipe ramming is a trenchless method for the installation of steel pipes used when sandy soil is present and impact moling is not possible, or where larger pipes or ducts are required.
The pipe rammer is locked into the end of the steel pipe and the pipe is driven through the ground by pneumatic percussive blows to one end. The soil is forced internally up the pipe and on completion is then augered out.
The pipe can then be used as a water pipe (irrigation), drain or as a duct for another service.
