Impact Moling

Mole Group have been trenchless installers since 1986 – which makes us one of the first in the UK.

Impact moling is a method of underground pipe installation that uses a pneumatic hammer to drive a steel pipe into the ground. It is typically used to install new pipes or to repair existing pipes that are difficult to access.

We can harness impact moling as a trenchless technique to swiftly and accurately install cables and utilities underground, reducing excavation and surface disturbances while maintaining efficient installation.

Method: Drill or Mole?

To determine if we will need to drill or mole, the factors we consider are:

  • Ground conditions

  • Distance to cover

  • Launch accessibility

  • Pipe diameter

  • Depth requirement

  • Underground obstructions

This method is ideal for both waterpipe replacements/domestic services.

Moling is a trenchless method of laying pipes or cables underground, where a pneumatically driven machine known as an Impact Mole forces a path through the ground, displacing soil rather than removing it.

Impact Moles come in all sizes, from 25mm diameters up to around 63mm in diameter. We will pick the appropriate size Mole for your project, and it tends to be a quick and simple way to install smaller pipes underground.
