Trenchless technology refers to construction methods for installing new pipelines or rehabilitating existing pipelines in areas where traditional open-cut construction would not be permitted, practical or possible. Examples of typical trenchless technology applications include pipeline crossings under highways and railways, rivers and lakes, steep slopes, environmentally sensitive areas, city streets and other developed areas.
Over the past 20 years, GeoEngineers’ staff experts have completed more than one million feet of trenchless projects, including pipelines from 4 to 116 inches in diameter, installed by horizontal directional drilling (HDD), microtunneling, Earth Pressure Balance Machine (EPBM) tunneling, pilot-tube-guided boring, pipe ramming, shield tunneling, auger bore and jack, pipe bursting and pipe reaming. We have completed hundreds of HDD pipeline crossings throughout the United States, Central and South America, Asia, and Africa with lengths in excess of 8,000 feet and pipe diameters up to 56 inches.
Within the trenchless market, GeoEngineers has a particular expertise with United States Army Corps of Engineers (USACE) design and permit requirements for trenchless technology crossings of levees. In fact, our work on hydraulic fracture and fluid loss is incorporated in an official USACE publication on installing HDDs under levees. This expertise is recognized worldwide and has made our firm a leader in geotechnical site characterization studies for pipeline crossings.
We assist our clients in all phases of trenchless technology projects as part of an integrated suite of services, including:
We've found that advanced planning is one key to pipeline project sucess. If you have a project that's nearing the pre-planning stages, we invite you to contact us to discuss your project needs with one of GeoEngineers’ trenchless technology specialists.
