Horizontal Directional Drilling
Precise installation of underground services without trenching. Diameters from 2" to 26" with ranges up to 2000 meters.
What is Horizontal Directional Drilling?
Horizontal Directional Drilling (HDD) is a trenchless underground construction technique that allows the installation of underground pipes, conduits and cables without the need to excavate from the surface.
This technology uses a steerable drilling head that can navigate around obstacles and follow precise trajectories, making it ideal for urban areas, environmentally sensitive zones and crossings under rivers, roads and railways.
Drilling Process
Pilot Drilling
A small diameter pilot hole is drilled along the designed trajectory using a steerable drill head.
Reaming
The pilot hole is enlarged to the required diameter using progressive reamers.
Pipe Pullback
The product pipe is attached and pulled back through the enlarged hole.
