What is Horizontal Directional Drilling (HDD)?
Horizontal Directional Drilling (HDD) is a trenchless method used to install underground pipes, cables, and utilities without digging large trenches. It involves drilling a guided hole along a planned path and then pulling a pipe or conduit through it.
Pilot Drilling – A small, guided drill bores a hole along the planned path.
Hole Enlargement – The hole is widened using special tools.
Pipe Installation – The final pipe or cable is pulled through the hole.
Less Surface Disruption – No need for large trenches, protecting roads and landscapes.
Cost-Effective – Reduces labor and restoration costs.
Ideal for Hard-to-Reach Areas – Works under rivers, roads, and buildings.
HDD is widely used for installing water, sewer, gas, telecom, and power lines, making it a smart, efficient, and environmentally friendly choice.
