SYNOPSISThe primitive ‘age’ of trenching has been with us for a long time, but it is now being overtaken by the ‘New Age’ of trenchless technology. If the benefits of the ‘New Age’ are to be fully realized, there must be proper co‐ordination of utilities' pipes and cables under urban streets.

Developments in trenchless technology
Tunnelling and Underground Space Technology, 1989Abstract It has been a matter of economic necessity to improve the efficiency of old underground plants by devising systems of rehabilitation rather than by providing the much greater funds required for their traditional replacement. With the worldwide “explosion” in surface traffic, replacing outworn services and installing new ones by disruptive ...
