What Is Trenchless Technology? Underground utility work in Ontario does not have to mean tearing up roads, disrupting traffic, and spending weeks on surface restoration. Trenchless technology offers a faster, less disruptive alternative, and understanding how it works can help municipalities, contractors, and utility providers specify the right method for their next project. Trenchless technology, also called no-dig construction, is a group of underground construction methods

Key Takeaways Hydrovac excavation uses high-pressure water to break up soil and an industrial vacuum to remove it into a truck-mounted debris tank. No mechanical equipment contacts the ground. It is the standard excavation method for scopes where buried infrastructure is present and mechanical digging would create unacceptable damage risk. Applications include slot trenching, curb-stop repair, frozen ground excavation, personnel maintenance access holes, drill fluid removal,

Key Takeaways • Open-cut per-foot installation cost is often lower, but total project cost frequently favours trenchless once restoration, traffic control, and excess soil management are factored in. • Ontario’s O. Reg. 213/91 imposes escalating safety requirements for open-cut excavations beyond 1.2 metres deep, including shoring, engineered support systems, and professional engineer involvement at 6 metres. • Municipal tenders that default to open-cut without requiring m

Key Takeaways • Horizontal directional drilling (HDD) installs underground utilities in three stages: pilot bore, reaming, and pullback. Each stage serves a distinct function and requires different equipment configurations. • The pilot bore is steered using a sonde transmitter tracked by a walkover locating system, allowing the operator to navigate around existing utilities and maintain the designed bore path. • HDD installs water, sewer, gas, electrical conduit, and fibre
