HORIZONTAL DIRECTIONAL DRILLING

Loy Clark Pipeline, founded in 1957, has been a pioneer in the horizontal directional drilling industry and a local pioneer in the HDD industry since the late 1980s. In that time, we have become an elite provider in the directional drill industry due to our broad experience, highly trained workforce and state-of-the-art equipment. Loy Clark Pipeline was one of the first companies to own and operate directional drills in the Portland Metro area. Our exceptional performance for more than two decades has earned us a proven track record that speaks for itself within the industry. We employ some of the best directional drillers in the horizontal directional drilling field, where there is no substitute for experience.

HDD technology

Since the 1980s, horizontal directional drilling technology has grown and developed exponentially. These machines now allow underground infrastructure to be installed without the need to disturb or remove most of the ground or hard surface above the installed infrastructure. In addition, the new utility will be installed while the bore head and steel are being guided by the crew and the machine’s electronics to avoid existing underground infrastructure so a new utility can be installed from the entry to the exit points of the bore. Whether it be a single half-inch service line or a multiple conduit duct bank, with this technology we can complete installation with less disruption to your yard, sidewalks, parking lot and/or streets.

In addition to hard surface areas, horizontal directional drilling technology can be used to install utilities under waterways, such as creeks, rivers, pond and lakes. The electronics can maintain both depth and direction so even waterways can be crossed in a safe and efficient manner. Another benefit and use of horizontal directional drilling technology is that it can be used to install infrastructure beneath sensitive areas, such as established landscape areas, old growth forests and riparian zones, all while causing minimal disturbance to the surface or to the sensitive ecological areas, thereby adhering to the strict municipal, county, state and federal environmental laws and other green initiatives.

Directional drilling fleet

We have a fleet of directional drills that range from a pull-back power of 5,000 to 60,000 pounds with the capability to bore and install pipe ranging from one to 36 inches in diameter in either single or multiple pipe configurations and length of runs up to 1,500 feet (based on pipe size). Due to our deep experience in the horizontal directional drilling industry and the fact that we own and operate several all-terrain drill machines, our crews have become efficient in all types of subsurface conditions that provide us the capability of drilling in clay, sandy, cobble, solid or fractured formations. We operate a state-of-the-art modern fleet of directional drilling equipment that is maintained by our in-house, full-time mechanics, welders and mobile service vehicles who work out of the shop at our headquarters building.

Loy Clark Pipeline provides service for both residential and commercial customers, as well as public utility entities. We are equipped to install underground natural gas, electrical, phone, cable television, domestic water and sewer infrastructure. At Loy Clark Pipeline, our primary focus is on you, the customer.
