INTRODUCTION TO TRENCHLESS TECHNOLOGY

Trenchless Technology involves the installation, replacement or renewal of underground utilities with minimum excavation and surface disruption. Several construction techniques and methods qualify as trenchless.

Trenchless technologies are and have been used successfully for all underground utilities from, water, sewer, gas, and industrial pipelines to electrical conduit and fiber optics.

Trenchless Technologies are a particularly attractive construction options in urbanised area with heavy vehicular and pedestrian traffic and numerous existing underground utilities. Trenchless is an attractive option for crossing roadways, and other transportation corridors, and rivers and waterways. Trenchless also can be used to install, rehab or replace utilities located in environmentally sensitive areas and locations where surface access may be restricted due to the existence of structures or vegetation.
