United Structural Systems’ Commercial Division

Shotcrete application is the pneumatic application of concrete onto a vertical or horizontal surface in order to stabilize soil or structures. It uses a wet-mix method, meaning the concrete is premixed and pumped through the hose. USS uses shotcrete application often in commercial projects as it is a great solution for adhering concrete to irregular structures and vertical walls. Common applications of shotcrete include pools, drains, and vertical cliffs on roads. We also perform gunite application, which is a dry-mix method of concrete application where concrete is applied dry but water is injected inside the hose before application.

Soil nails

If you are in need of earth retention systems, USS is your Murfreesboro expert at soil nailing – a type of retention system that uses anchors in a grid pattern with a reinforced shotcrete face. Most often soil nails are used for temporary construction walls or excavations for buildings, plants, or parking structures. However, soil nails have a wide variety of uses in other situations. Our experts can change the design of your soil nailed walls based on site conditions, meaning your project keeps moving at a good pace whatever challenges present themselves.

Underpinning and foundation repair services

We are Murfreesboro’s construction companies and engineers’ number one choice for underpinning and foundation repair services. From residential projects such as the Brighton Valley Apartments or Hickory Glade Condos, to government buildings like the U.S. Post Offices of Antioch and Brentwood or the Montgomery County Municipal Buildings, USS has proven our expertise when it comes to underpinning. This method of foundation repair is similar to residential home foundation repair in that it extends the load bearing portions of the foundation into deeper, more stable bedrock. We hydraulically drive the piles into the bedrock and use them to lift your structure back into its original elevation.
