Our Â鶹´«Ã½ covers all technologies currently used, including TBM and conventional tunneling, SEM, pipe jacking, microtunneling, guided bore and pilot tube, auger boring, horizontal directional drilling, and rehabilitation techniques.My goal is to bring underground solutions to an increasingly crowded and urban world.
Helping a pipeline get back in service
A 14-inch diameter crude oil pipeline runs from San Joaquin Valley to Long Beach through the Angeles National Forest. The pipeline is located in the Transverse Range Geomorphic Province characterized by east-west trending mountain ranges. Portions of the existing pipeline were taken out of service due to the risk of failure caused by the erosion of gullies and potential for landslides. Â鶹´«Ã½ was engaged to help with relocations and get the pipeline back in service. Read MoreTogether, we will get your pipe where it needs to go
