Trenchless or no-dig technologies are those which enable utilities such as watermains, sewers, and cables to be installed, repaired, or renovated without the need to excavate a trench. This document is an introductory guide to some of the available trenchless technologies specifically designed for non-man-entry sized pipelines and utilities. Each section of the guide contains a summary description of the technology and its applications, accompanied by reproductions of commercial literature from manufacturers and service providers of trenchless technologies. The technologies reviewed include hydro-cleaning, resin repairs, sliplining, sprayed cement mortar lining, inverted polyester lining, renewal by pipe-bursting, renewal by pipe replacement using microtunneling, directional boring systems, and microtunnelling systems.
