Home About Us Boring Tunneling HDD Communications Shaft Construction Safety Consulting Contact Us Boring Technology Auger Boring Pilot Tube Microtunneling Slurry Boring Boring Technology Boring Technology consists of several methods each designed to cut a hole through the earth and install smooth, round pipe through the hole. The initial step with each of the techniques is to establish a path for the bore. The drill, auger or pilot is then advanced from the launch shaft to the exit shaft along this path. Guidance methods vary depending on the bore method selected. Ground conditions, the amount of ground cover above the hole, the size and length of the bore, and the presence of ground water must each be assessed to determine which type of bore will be most successful. While the physical process of creating the hole can be similar, the machines and tooling required for different types of bores varies greatly. For a comparison of the different types of bores, follow the Boring Method Selection link for a chart. We’re here to help!

Home About Us Boring Tunneling HDD Communications Shaft Construction Safety Consulting Contact Us Ring Beams & Lagging Rib and Lagging is a primary tunnel liner used to shore horizontal excavations in soft ground. A rib and lagging tunnel is formed by constructing rings made of wide flange beams which support steel or wood lagging. Once a rib is installed, it is expanded in place. This expansion compacts the material outside of the tunnel eliminating the need for grouting. These tunnels can be built in a variety of shapes including round, square and arch. We’re here to help!

Home About Us Boring Tunneling HDD Communications Shaft Construction Safety Consulting Contact Us Soldier Pile Shaft Soldier pile shafts are used for large, deep excavations where a large working area is required below grade. These shafts are installed by drilling and sinking I-beams or concrete piers around the proposed excavation and driving steel plates between the beams. The ground is excavated as the plates are installed. Timber is often used in Soldier Pile Shafts as an entry or exit portal for trenchless construction. For extremely large and complex shafts, concrete walls may be poured in place for the shaft walls. We’re here to help!
