Economics of Trenchless Technology
1992Operators are faced with the difficult decision of determining when it is economical to use trenchless methods over conventional technology. Trenchless methods have been historically selected for the following reasons: 1. Restoration costs are high. 2. Municipal authorities prohibit the open-cut trenching of key streets or highways.

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 ...
