Tunneling is the process of installing large pipe, box or liner through excavation of a horizontal hole. Tunneling is trenchless excavation, allowing for installation without disturbing the surface, particularly useful when utilities must cross beneath existing infrastructure.
Tunneling may be accomplished through either hand mine techniques, or through use of large Tunnel Boring Machines (TBM’s). TBM’s are designed to bore through different types of materials, from hard rock to softer materials including mixed soil or even wet sand. We are skilled in a variety of tunneling methodologies, adaptable to the project requirements and the geological conditions.
