Home About Us Boring Tunneling HDD Communications Shaft Construction Safety Consulting Contact Us Tunneling Pipe Jack Tunneling Tunnel Liner Plate Ring Beams & Lagging Wood Box Tunneling 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. We’re here to help!

Home About Us Boring Tunneling HDD Communications Shaft Construction Safety Consulting Contact Us Slurry Boring Slurry boring is named for its use of bentonite drilling fluids during the boring process. A slurry bore is initiated by “shooting” a pilot along the desired line and grade. After an accurate pilot is established, the bore hole is reamed by a cutter head to the desired diameter. The product pipe is then pushed into the open hole. Slurry boring is also known as “slick boring” or “wet boring.” We’re here to help!
