Soil Nail Walls
Drill Tech has innovated soil nail design and construction for over 20 years. The process involves reinforcing existing soil by installing closely spaced steel bars (soil nails) into a slope or excavation face at a slight incline. These walls are typically constructed top-down in staged excavations.
Construction Process
Soil nail walls are constructed top-down in stages; steel bars are installed in rows at descending heights to reinforce the soil. The facing can then be finished in a variety of ways using shotcrete; our technicians often sculpt and stain facings to resemble natural rock or smooth the shotcrete down for a trowel flat finish. Soil nail walls are feasible in virtually any dewatered ground condition and can be used for permanent retaining walls as well as temporary shoring. Drill Tech has experience installing soil nail walls ranging between 5 and 130 feet in height.
Benefits of Use
Soil nail walls are highly versatile and can be installed in almost any ground condition. Drill Tech’s engineers and project managers have working relationships with countless cities, counties, developers, and government agencies, so the review and approval process is expedited for our projects. Our custom-built drill rigs consistently outperform our competition, which allows for quick, cost-efficient design and construction.
