Trenchless Technologies

What are Trenchless Technologies?

Trenchless technologies are innovative means of placing pipes, conduits, and fibres below pavement and other surfaces without having to create surface-level, open-cut trenches. Horizontal Directional Drilling, Microtunneling, and Pilot Tube Microtunneling allow trenches to be drilled below ground where an enlarged borehole is created, and the pipe or other material is pulled the length of the underground trench.

Trenchless technologies eliminate severe surface disruption, which is typically an unavoidable side-effect of open-cut trenches. By laying the material below the ground’s surface, trenchless efforts remove the need for costly surface restoration and minimize disturbance to surrounding areas.

The technologies are more economically viable, as the trenchless installations reduce much of the clean-up and restoration costs incurred by open-cut trenches. In situations where open-cut trenches are not practical, such as installations that must occur across waterbodies, trenchless technologies provide invaluable alternatives that allow the construction to be efficiently completed.
