There are several methods of trenchless cable laying, each suited for different site conditions and project requirements. The two most common methods are:

• Horizontal Directional Drilling (HDD): This is the most widely used method. An HDD rig creates a pilot bore along a pre-determined path. The bore is then enlarged, and the cable or conduit is pulled through from an exit pit to the entry pit. This method is ideal for crossing rivers, roads, and other busy or sensitive areas.

• Mole Ploughing: This method is a more direct approach for laying cables in open ground, such as fields or rural areas. A powerful tractor or winch pulls a plough with a vibrating blade through the ground. The blade creates a narrow slit, and the cable is simultaneously fed into the ground directly behind the blade. This method is exceptionally fast and cost-effective for long, straight runs.
