Directional drilling, often referred to as horizontal directional drilling, is a technique used to install pipes and ducts along a carefully planned underground route. The process starts with a small entry pit, followed by a guided pilot bore along the required alignment. Once the bore is complete, the new pipe is drawn back through and positioned in place.
Modern compact drilling rigs are well suited to property connections and smaller diameter utility installations, including gas, water, electricity, fibre broadband and pressurised drainage systems. This method allows the bore to curve, change depth and navigate around existing underground services where needed.
