Rock Drilling
Rock Drilling or Horizontal Directional Rock Drilling as it is sometimes referred to provides a safe solution of installing pipes, cables and ducts when traditional HDD methods are not acceptable or practical due to high strength ground conditions.
This technique enables non-displacement boring into solid rock, gravels, cobbles and boulders.
With diameters ranging from DN63 to DN710mm available, this method is suitable for the installation of steel and Polyethylene pipes.
With our specialist equipment and experienced operators, we have the upmost confidence in successfully installing pipelines in the toughest of locations/ground conditions.
What can we do for you?
Distances: Pipe lengths up to 400 metres.
Installation rates: Up to 20 metres per day dependent on the required diameter and the ground conditions.
Accuracy: +/- 50mm Ground dependent.
Pipe installations: Diameters varying from 63mm to 710mm
Advantages of Horizontal Directional Rock Drilling
-
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
-
Relatively small overall footprint for the Works
-
Pipework and cables can be installed in either a straight or curved alignment to help avoid underground complications and services
-
Able to install ducting in ground conditions that are too aggressive for conventional open cut / drilling methods.
-
HDD requires no deep excavations due to the equipment that is used
-
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
