Schnabel

Civil engineering can be dated to the very first time someone placed a roof over their head. These days, it encompasses every critical part of the built environment from roads and bridges to canals, airports, dams, sewerage systems, railways, pipelines and much, much more. If you have a career in civil engineering, you’re a part of a critical and honorable profession that gives you the opportunity to help design and construct the world around us. At Schnabel, our civil engineers have even greater opportunities, because we are a design-build company with a nationwide footprint. What Makes Schnabel Different? At Schnabel, our civil engineering recruiters are always looking for talented individuals to help design, build and supervise the geostructural projects we’re known for. Balancing design, construction, field and office work experience, this exciting position exposes you to different facets of our business while allowing you to grow your career. A longstanding family-run organiz...

  Underpinning is used to transfer the load from an existing structure’s current foundation level to a deeper level in the ground. There are several reasons why this may be required. Often an excavation for a new structure will occur within feet or inches of an existing foundation, and the bottom of the new excavation will be lower than the bottom of the existing foundation. To prevent damage to the existing structure, its foundation may need to be extended to an elevation below the bottom elevation of the proposed excavation using underpinning  Learn more here: https://posts.gle/usM9m

Tiebacks are used to provide the lateral resisting force for many of the excavation support systems and anchored retaining walls that Schnabel builds. They are constructed by grouting a high strength steel bar or strand bundle into the soil or rock behind the failure surface of the retaining wall. After the grout has cured, every tieback is tested, and the load is locked in to limit movement. Learn more: https://posts.gle/s3Ekj  

Soil nailing is an in-place reinforcement of the existing soil/rock at a site that utilizes steel tendons grouted into drilled holes to create a stable block. Shotcrete, reinforced with wire mesh and/or reinforcing steel, is applied to the face of the excavation to secure the soil between the nails. Soil nailing is installed from the top down as an excavation is made in 4 to 6-foot lifts. Learn more here: https://posts.gle/QWBYp

Proper soil mixing is an essential step in creating durable earth-retention solutions. When done correctly, the mixing process yields a soilcrete mixture that has both increased strength and reduced permeability. Learn more here => https://posts.gle/udNEd

Shotcrete is a pneumatically applied low-slump concrete that is blown onto the receiving surface with compressed air. Shotcrete has a relatively low water/cement ratio, high cement content, and typically small aggregate not exceeding pea gravel size. High compressive strengths in excess of 5,000 psi are commonly attained. The sticky nature of shotcrete allows it to be placed on vertical and even overhead surfaces without the need for formwork. With proper quality control, a wall surface can be built out to an 8- inch thickness or more in a single pass. Learn more here: https://posts.gle/abx5f

  Secant pile walls are constructed by drilling in a series of alternating primary (drilled first) and secondary (drilled second) overlapping shafts to form a continuous secant wall. The concrete in the shafts can be all low-strength, all high-strength, or a combination of low-strength primary and high-strength secondary shafts. Steel piles or reinforcing steel are typically placed in the secondary shafts. Unreinforced high-strength shafts can also be constructed in a self-supporting circular ring, such as those frequently used for access shafts to tunnels.

  Permanent tieback, soil nail and cantilevered pile retaining walls are a practical and economical solution when a permanent wall is to be built in a cut or partial cut-and-fill situation. This is particularly true when it is desirable to leave a road, structure, slope or other feature behind the wall undisturbed. Learn more here: https://posts.gle/Yrkry

Micropiles are small-diameter, typically 12 inches or less, deep-foundation piles. Because they can be installed with relatively small drilling equipment, micropiles are a cost-effective foundation system inside existing buildings, under existing bridges, and in other types of low-overhead or restricted-access conditions. An innovative micropiles construction company, Schnabel has specialized drills that can even travel through a standard doorway and drill under an 8-foot ceiling.

  A landslide occurs when the driving forces on a soil mass exceed the internal resisting forces of that soil mass and the land starts to move. Schnabel’s landslide repair service utilizes proven techniques to stop or prevent a landslide including installing tieback anchors, soldier piles, and/or micropiles to provide additional external resisting force.

  Also known as shoring, excavation support systems (ESSs) are designed to support the ground behind an excavation. The excavation support system may also be designed to resist groundwater pressure, building loads, construction traffic, roadways, railroads, and many other types of surcharge loads.
