GEOSYNTHETIC USE IN TRENCHLESS PIPE REMEDIATION AND REHABILITATION

The traditional method of repairing broken or otherwise nonserviceable underground pipes is by excavation (usually requiring sheeting and shoring), pipe removal, pipe replacement, backfilling and then restoration of the site to its original condition. With the advent of an array of trenchless pipe construction techniques, the remediation and rehabilitation of underground pipes (particularly sewers) has drastically changed. These trenchless methods only require access at periodic locations (often at existing manholes) thereby eliminating most of the objections associated with traditional construction operations. The currently used trenchless techniques for pipe remediation and rehabilitation are described in this paper. They will be accompanied with commentary on their respective advantages and disadvantages. Typical costs and other details will also be presented. Focus is placed on those systems which employ geosynthetics or other polymeric materials. While the main application area is on underground sewer pipelines, the transition of the presented material to other underground pipeline and tunnel situations can readily be made.
