When deep excavations and retaining walls demand reliable lateral support, tiebacks deliver the counterforce your structure needs. Hark Drilling designs and installs retaining wall tie backs across the Intermountain West, helping developers, general contractors, and municipal planners anchor earth retention systems in some of the region's most demanding soil and rock conditions.
A tieback is a tensioned anchor installed at an angle through a retaining wall and into the stable ground behind it. The anchor is drilled into place, grouted, and, once the grout has cured, stressed with a hydraulic jack and locked off to apply a permanent load against the wall. That counterforce offsets the lateral pressure of the retained earth, minimizing wall deflection and protecting adjacent structures, utilities, and roadways as excavation progresses.
Tieback retaining wall systems are often paired with complementary earth retention methods, including:
Soldier pile and lagging walls
Drilled shaft and shotcrete walls
Soil nail systems
Micropile foundations

Our retaining wall tieback anchors are built from either high-strength steel bars or multi-strand cables, each with a defined bond zone and free length engineered for the specific load requirements of the project. We install tiebacks up to 100 feet deep, accommodating both temporary shoring during construction and permanent anchor systems designed for long-term wall stability.
Reduced wall deflection during deep excavation, particularly where sensitive structures sit behind the wall
Greater design flexibility for taller walls and tighter site footprints
Versatile application across commercial, infrastructure, and transportation projects
Adaptable to variable ground conditions, from dense clay to fractured rock
Streamlined coordination when paired with other Hark shoring and earth retention services


From the Wasatch Front to the Sonoran Desert, Hark Drilling understands how regional geology shapes a successful tieback installation. In Utah, we regularly engineer anchor systems for hillside developments along the Wasatch Range, basement excavations in downtown Salt Lake City, and infrastructure projects navigating the lake-sediment soils of the Great Salt Lake Basin.
In Arizona, our crews install tiebacks through the caliche layers of the Phoenix Valley, the weathered granite around Tucson, and the red sandstone formations near Sedona and Flagstaff.
With offices in both Salt Lake City and Phoenix, we mobilize quickly and bring region-specific knowledge to every job, whether that's a commercial basement cut in Lehi, a parking structure in Tempe, or a DOT shoring project in between.
