Horizontal Directional Drilling (HDD)

Horizontal Directional Drilling (HDD) is a minimal impact trenchless technology for installing pipes, conduits, and cables in underground bore-path construction. This technology allows us to install pipe or conduit under roads, rivers, and existing structures without disrupting the surface.

Directional boring is useful because it makes boring underground holes possible without disturbing the surface. It reduces surface disturbance and minimizes impact on traffic and residents. Also, the HDD technique is used when conventional excavation is not practical or when minimal surface disturbance is required. Directional boring is safe, fast, environmentally friendly, and suitable for many soil conditions.

This method comprises a three-stage process. In the first stage, a pilot hole is drilled on the pre-determined path. The second stage enlarges the hole by passing a larger cutting tool knows as the reamer. Finally, the pipe or conduit is placed in the enlarged hole.

We can bore from 3/4 inch to 12 inches in diameter.

• Safer for workers
• Safer for the environment
• Avoids extensive open cut trenches
• Minimal surface disruption compared to traditional methods
• Reduces risk of groundwater pollution
• Faster installation times
• Limits traffic disruption

• Underground conduit installation (telecommunications or power)
• Underground pipe installation (water or natural gas)
• Pipe rehabilitation
