Directional drilling is a versatile solution for various underground utility installations, offering minimal surface disruption and efficient project execution. It is commonly used for solar bores, driveway crossing bores, and parking lot light conduit replacements. Golf courses benefit from directional drilling for irrigation and utility installations, while drainage bores help manage water flow effectively. Fire hydrant water lines, typically requiring a 6-inch bore, and force main sewer bores also rely on this method. Additionally, it is ideal for electric car charger installations, ADU utility connections, and major infrastructure projects like water main and sewer bores. Utility providers, including PG&E, use directional drilling for fiber optic and power line installations, as well as gate electric and sign power bores, ensuring reliable and efficient underground connections.

We specialize in precise, short directional drilling bores for residential and commercial applications, ensuring minimal footprint and disturbance.
