One of the nation’s premier shotcrete contractors and specialty foundation companies, Schnabel provides tailored solutions for unique project challenges. When uneven surfaces complicate the construction process, Schnabel can install reliable shotcrete retaining walls to ensure the structural integrity of your project.

Shotcrete is a special mix of concrete that is sprayed pneumatically onto a vertical or sloped ground surface. Shotcrete is typically used in conjunction with other elements such as soil nails to provide a safe and reliable earth-retaining solution.

A leading Geostructural Design & Construction contractor, Schnabel has the expertise to provide durable shotcrete retaining walls for your unique construction project.



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.

An experienced shotcrete contractor, Schnabel typically uses shotcrete to build temporary and permanent facings for our soil nail retention walls, but it can also be used as a facing for any other type of earth-retaining wall. For soil nail walls, a temporary shotcrete layer of 4 to 6 inches is applied directly to the excavated ground surface. If the wall is to be permanent, an additional 6 to 12 inches of reinforced shotcrete will be applied after the soil nails and temporary shotcrete are installed. The surface of the permanent facing can have a finish that varies from sculpted and stained to gun finished or finish-troweled, similar to a formed concrete wall.

Contact one of Schnabel’s branch offices to see if shotcrete retaining walls are right for your project.

Positive outcomes are the inevitable outcome.

Southeast Corridor Multi-Modal Project (TREX)

Schnabel designed and constructed ten permanent soldier beam and lagging tieback walls finished with a 10-inch permanent shotcrete facing for the Southeast Corridor Multi-Modal Project (TREX) in Denver, Colorado.

The 725 Ponce project was one of the first projects in Atlanta where Schnabel installed permanent shotcrete walls for the below grade basement of the structure. The basement are typically cast-in-place concrete, however, on this project the shotcrete system proposed by Schnabel improved the overall project budget and schedule.
