At GM Contracting, we provide high-quality trenchless piercing services to install service lines and small-diameter mains with minimal excavation. Our team utilizes small-diameter underground piercing tools that are pneumatically powered, making them ideal for water services and sprinkler systems. With the help of our piercing tools, we are able to complete horizontal boring underground at distances up to 100 feet with precision and accuracy.

Our trenchless piercing process begins by excavating a small launch pit at the main and another at the residence. The piercing tool is then positioned and lined up with the exit pit, and launched with its pneumatic action carrying it through the ground to the exit pit. Once the tool reaches the exit pit, the air hose is removed and the new pipe is attached to it. As the air hose is pulled back through the borehole, the new pipe is pulled into place.

Our trenchless piercing services allow us to install service lines and small-diameter mains with minimal surface disruption, making it an ideal solution for areas where excavation is not feasible or practical. We pride ourselves on our precision and accuracy, and our team is committed to providing our clients with high-quality, cost-effective solutions for their underground utility needs.
