Earth Retention

Earth Retention systems are constructed to provide excavation shoring and support, and to 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.

Earth Retention Systems

Drill Tech Drilling & Shoring, Inc. designs and builds earth retention systems for numerous applications

Including excavation shoring, landslide mitigation, and permanent/temporary retaining walls. We routinely utilize soil nail walls, soldier pile walls, tieback anchors, sheet pile walls, and cutter soil mixing for these applications.

Soil Nail Walls

Drill Tech has innovated soil nail design and construction for over 20 years. On average, we construct approximately 1,000,000 square feet of soil nail walls each year, and our engineers have designed over 1,000 individual soil nail walls.

Tie Back Anchors

Tie Back Anchors

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.

Cutter soil mixing equipment

Cutter Soil Mixing

Drill Tech is continually at the forefront of the geotechnical industry, utilizing innovative new technologies for earth retention and ground treatment. Over the past 15 years, Drill Tech has expended a tremendous amount of time and effort to further develop the use of the cutter soil mix method for earth retention and ground treatment needs.

Retention Secant Pile Walls

Soldier Pile Walls

Soldier pile walls are earth retention systems that provide support through steel beams below the surface. Our team has experience installing soldier pile walls in both “fill” and “cut” wall projects and has found them especially beneficial for projects along property boundaries. Soldier pile systems are effective in both permanent retaining walls and temporary shoring solutions.

Ground Treatment Project

Secant Pile Walls

Mitigate slope instability and provide excavation shoring and support with earth retention systems—good for permanent structures or temporary shoring during a project. We design our systems to stabilize lateral earth pressures, control movement, and drain potential water pressure.

Sheet Pile Walls

Sheet Pile Walls

Support weak soil with deep foundation systems designed to transfer structural loads to stronger soil or rock below the surface. Our foundation support systems consider axial and lateral loads, uplift force resistance, and settlement control.
