Horizontal directional drilling (HDD) is a trenchless method of installing underground utility lines — water, sewer, conduit, and more — without digging an open trench. We bore a precise path underground and pulled the utility line through, minimizing surface disruption above.

Yes—that is one of our primary specialties. Our directional drill is specifically designed to navigate around and beneath obstacles that traditional excavators cannot address, including paved roads, building foundations, and established root systems.

Our Hydrovac Jetter is a large truck-mounted system that uses pressurized water and vacuum extraction to safely expose buried utilities without the risk of damaging them with mechanical digging equipment. It is also used to jet and clean sewer lines six inches in diameter and above—a service that is especially valuable for municipal sewer main maintenance and repair projects.
