Frequently Asked Question

Is Underboring Better Than Trenching?

Neither method is always better; the route, surface, grade and service decide.

Underboring is often useful for a direct crossing beneath a driveway, road, footpath or slab. Trenching is usually more flexible for long runs, multiple branches, pits, drainage grades and work that needs full exposure.

Compare the complete job: access, existing services, surface restoration, length, connection points and the following trade's requirements. The right method protects the project, not just the surface.
