Specializing in horizontal directional drilling since 1984, J-C General Engineering, Inc. has developed into one of Northern California’s most reliable underground utility contractors. Our company is based out of Lodi, CA, where equipment is maintained and modified in a state of the art metal fabrication shop. Owned and operated by John Coughran, J-C General successfully continues to increase in assets to facilitate job variance. Four different sized drill rigs along with the latest locating technology allow J-C General to produce jobs ranging in any size or sedimentary formation up to 4000 feet. In the 25 plus years of the company’s history, there has yet to be a job that J-C General has been unable to complete. We take pride in the work that we do and guarantee a quality that few companies can match.
