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 Drilling is an industry leader in of ground anchor solutions. Our ground anchor drill rig fleet consists of several dozen machines, including conventional Klemm 803, 806 and 807 tieback machines, custom built excavator and forklift mounted, crane suspended drill basket platforms, and an 80 foot stroke “rocket launcher” drill. Drill Tech Drilling has successfully installed ground anchors in every imaginable type of ground, with design loads in excess of 2,000 kips and lengths in excess of 300 feet.
The steel tendons have a free stressing (unbonded) length and a bonded length. The bonded portion of a tieback is the length of the tendon bonded to the anchor grout and transmits the applied tensile load into the ground. The unbonded length is the portion of the tendon that is free to elongate and transfer the resisting force from the bond length to the anchorage. Tieback anchors can be corrosion protected with epoxy coating or corrugated plastic sheathing to provide a permanent service life. For temporary shoring applications, bare strand or bar can be used.
