Trenchless Technology is the science of installing, repairing or renewing underground pipelines, ducts and cables using techniques that minimise or eliminate the need for excavation. The use of such techniques has been proved to reduce the cost, environmental and social impact of utility works. The field of Trenchless Technology can be divided into four main areas:-

• The location and inspection of existing buried services
• Rehabilitation techniques such as cleaning, patching and re-lining
• Replacement techniques such as pipe bursting, pipe splitting and pipe extraction
• Installation techniques such as auger boring, tunnelling, pipe-jacking, impact moling & HDD
