Impact Moling

Impact Moling For Installing or Replacing Pipework From 20mm to 32mm Over Distances Of 1 – 20 Meters.

Here at ADI Water Mains Replacement Impact Moling is just one of the three forms of underground technologies that we utilize.

Impact Moling is used to create brand new pipe runs underground, or to replace existing pipe runs by creating new runs next to the aged/faulty existing runs or where existing pipework can not be accessed.

Impact Moling works by utilizing a sending pit (where the mole is sent from) and a receiving pit (where the mole pneumatically hammers its way to, from the sending pit). Both of these pits need to be approx 1 meter x 1 meter x 1 meter.

Our teams carry out these excavation points in the most cost effective locations for you – where possible.

Impact Moling is not always plain sailing, it does come with some risks and time consuming tasks when compared to other forms of underground pipe replacement.

  • Maximum Recommended Mole Run Of Only 8 – 10  Meters – (This is the maximum distance between sending & receiving pits, however multiple runs can be carried out for runs of over 8-10meters) – Horizontal directional drilling is the solution for installing water mains over longer distances.
  • The Moling Process does create vibrations through the ground, therefore moling carries a risk of damage to other underground services
  • The Mole is positioned in the sending pit at the correct angle to reach the receiving pit, however rocks can cause the mole to go “off route” – causing additional expense & possible damage to other underground services.

These risks associated with Impact Moling are reasonably uncommon, however where we are unable to use any other form of underground pipe replacement technology we would still need to use a mole, or resort to costly traditional open trench techniques.
