Helical Tieback Structural Reinforcement

In most cases, yes. If the seawall panel still has structural integrity, helical tiebacks can stop the movement and typically recover 50–80% of the displacement from vertical. Full straightening is rarely possible, but stopping further movement is achievable in virtually all cases.

Depth depends on the soil conditions and the depth at which stable, non-eroded soil is found. Most coastal Florida installations reach 8–20 feet into the soil behind the wall. We calculate the required depth using soil borings or local geotechnical data.

We use high-strength galvanized steel and marine-grade epoxy-coated hardware throughout. Exposed fasteners and waler hardware are stainless steel. Properly installed tiebacks in Florida's marine environment have 40+ year service lives.

Our hydraulic torque head equipment is compact and barge-mounted when installed from the water side. We can install tiebacks with a walk-behind torque driver from the land side in many cases, with no heavy equipment footprint on your lawn.

Traditional deadman anchors use a large concrete block buried behind the wall, connected by a tie rod. They require excavation and can fail if the soil between the deadman and wall erodes. Helical tiebacks are drilled deep into stable soil past the failure zone — they don't rely on the eroded backfill.
