Jack and Bore is a trenchless excavation method used to install steel casing and carrier pipes beneath roads, railways, and other critical infrastructure without open‑cut excavation. This technique provides a safe and reliable solution for crossing areas where surface disruption is not permitted.
The process involves excavating a launch pit, setting a boring machine on a guided track, and using hydraulic jacks to push steel casing pipe forward while simultaneously boring out the soil. As the casing advances, spoil is removed from inside the pipe, creating a clean, stable tunnel. Once the casing reaches the exit point, the carrier pipe—such as water, sewer, gas, or electrical conduit—is installed inside the casing.
Jack and Bore is known for its precision, structural integrity, and ability to handle large‑diameter installations in challenging soil conditions. It is widely used for municipal, industrial, and utility projects requiring minimal surface impact and long‑term durability.
