DIRECTIONAL & HORIZONTAL Drilling SERVICES

HDD (Horizontal Directional Drilling) is a trench-less technology that uses surface-launched equipment to drill underground horizontally and install pipes, conduits, and cables. HDD is used in several industries, such as utilities and telecommunications, at sites with limited space (e.g., dense, urban areas) or where traditional vertical excavations are too hazardous (e.g., under lakes and rivers). Although HDD technology is thought to take less time, require fewer workers, and cause less surface damage compared to traditional open trench excavations, it is more difficult to avoid utility lines when using HDD because of the limited visibility inherent to the process.
