Directional Drilling

Loy Clark Pipeline Company was founded in 1957 and has been performing horizontal directional drilling services since the late 80’s.  We have become an elite provider in the directional drill industry.  Loy Clark Pipeline was one of the first companies to own and operate directional drills in the Portland Metro area. Our exceptional performance for nearly two decades has earned us a proven track record that speaks for itself within the HDD Industry.

Loy Clark Pipeline's Drill Division has more than 100 years of experience within its work force.  We employ some of the best drillers in the HDD field where there is no substitute for experience.

We specialize in the small to mid-range drills with the capability to bore from 1” to 20” in diameter with single or multiple pipe configurations and lengths of over 1000’ feet (based on pipe size). We are experienced in all types of soil conditions with the capability of drilling solid or fractured formations.  We operate a modern fleet of directional drilling equipment that is maintained in-house, in our state of the art shop with full time mechanics, welders and mobile service vehicles.

Loy Clark Pipeline provides service for both residential and commercial customers as well as public entities. We are equipped to install natural gas, power, phone, CATV, water and sewer infrastructure. At Loy Clark Pipeline, our primary focus is on you, the customer.  Whether you are a small or large customer, we believe that exceptional service builds long lasting relationships.  We specialize in achieving customer satisfaction and delivering a quality product that will last.
