Earth Retention Systems

Stable Foundations and Retention Systems

The Ayers Advantage

We understand how to stabilize large industrial structures with stable foundations and earth retention systems. We’ve assembled the best products and professionals over decades of providing excellent service. When the foundation of your business is at stake, we bring stability and peace of mind.


Shotcrete is mortar or concrete that is applied as a spray, through a high-pressure hose and application nozzle. In the hands of a skilled operator, shotcrete offers the versatility to construct, repair, and reinforce walls, bridges, tunnels, channels, and other structural elements.

Shotcrete is an especially noteworthy innovation in concrete technology. Sometimes referred to as “wet gunning,” shotcreting involves spraying concrete or mortar through a high-pressure hose to fill a form, repair a damaged surface or cover an armature or other substrate.

Soil Nails

Soil Nails

Soil nailing is a method of earth retention that relies on reinforcing strands or members installed within a soil mass to create an internally stable gravity wall/retaining system.  

Helical soil nails consist of a square shaft lead and extensions with a diameter around 6 to 8 inches. Helix plates are spaced evenly along the entire shaft. The helical soil nail is installed by application of torque, similar to the installation of a helical tieback.

Our soil nail solutions have the following advantages:

  • More economical than conventional concrete
  • Typically shorter than tiebacks for similar wall heights
  • Less impact to adjacent structures
  • Quicker than other earth retention methods
  • Perform well during seismic loading events due to the overall system flexibility
