Earth Retention systems are constructed to provide excavation shoring and support and mitigate slope instability. Earth retention systems can have permanent service lives or only provide temporary shoring during construction activities. The design and construction of earth retention systems must consider stabilizing lateral earth pressures, controlling movement, and draining potential water pressure.
Drill Tech Drilling & Shoring, Inc. designs and builds earth retention systems for numerous applications including excavation shoring, landslide mitigation, and permanent retaining walls. We routinely utilize soil nail walls, soldier pile walls, tieback anchors, sheet pile walls, and cutter soil mixing for these applications.

Drill Tech has been an innovator in soil nail design and construction for geotechnical construction in the western United States for over 20 years. Our custom built drill rigs consistently outperform our competition allowing for faster and more cost-efficient design and construction of permanent and temporary soil nail walls. On average, Drill Tech constructs approximately 1,00,000 SF of soil nail walls each year.
Drill Tech’s staff of professional engineers has designed over 1,000 soil nail walls, ranging in height to 130’ tall. Our professional engineers and project managers have developed working relationships with countless cities, counties, developers, and government agencies to facilitate the review and approval process.
The concept of soil nailing is to reinforce and strengthen an existing ground mass by installing closely spaced horizontal ground anchors (soil nails). Soil nail walls are typically constructed in stages from the top down in “cut wall” applications and are feasible in virtually any dewatered ground condition. Drill Tech has installed soil nail walls ranging from as short as five feet tall to in excess of 130 feet tall.Soil nailing can be used for permanent retaining walls as well as temporary shoring. The shotcrete facing may then be finished in a variety of ways, from sculpted andstained to resemble natural rock, to a smooth trowel flat finish.
