What Are Commercial Helical Anchors & Tiebacks?
Helical anchors and tiebacks are steel shafts fitted with helix-shaped plates that are advanced into stable soil beyond the area of movement. They attach to a wall or structure to provide lateral support and help prevent further movement.
Unlike helical piers, which carry structures from below, helical tiebacks are typically installed at an angle to resist sideways forces. The helix plates transfer those forces into stable soil, offering support with no grout or cure time.
When Nashville Commercial Projects Need Helical Tiebacks
Helical tiebacks can stabilize retaining walls, commercial foundation walls and other structures that are leaning, rotating, sliding or bulging. Movement can also surface as horizontal wall cracks or shifts in pavement and loading areas behind the wall.
They can also supply lateral support on planned commercial projects, such as excavation shoring, soldier pile and lagging systems, seawalls and bulkheads, and tiedown applications where uplift or overturning forces must be resisted.
Our Commercial Helical Anchor & Tieback Solutions The Foundation Specialists
Leaning, Cracked or Overturning Retaining Walls
Permanent Helical Tiebacks for Walls
Permanent helical tiebacks provide lateral restraint for retaining walls, foundation walls, sheet pile walls, seawalls and other structures showing lateral movement. Installed through or behind the wall and driven into competent soil beyond the failure plane, the anchors carry lateral loads into stable soil to help stabilize the structure and resist further movement.
Excavations That Need Lateral Support Next to Existing Structures
Temporary Helical Tiebacks for Shoring
Temporary helical tiebacks deliver lateral support for excavation and shoring systems where surrounding soil needs to be restrained during construction. They can be paired with soldier pile and lagging, sheet pile and other earth retention systems, including work near existing buildings where excavation movement and available working space are key considerations.
Structures Resisting Uplift, Overturning or Lateral Thrust
Helical Tiedown & Tension Anchors
Helical tiedowns and tension anchors secure structures against forces that can pull, overturn or move them from their designed position. Advanced into load-bearing soil, these anchors can deliver tension resistance for new construction and other commercial applications where foundations or structural members must resist uplift, overturning or lateral forces.
How Commercial Helical Tiebacks Are Designed & Installed
Helical Tiebacks vs. Grouted Tiebacks & Soil Nails
Helical tiebacks install with no grout or cure time, need minimal excavation and can be loaded immediately after installation. Installation torque is monitored as each anchor is installed to help verify it meets project requirements.
Grouted tiebacks use grout to secure the anchor in the ground and can be better suited to certain high-load or rock conditions.
Soil nails take a different approach, strengthening the soil behind a wall or excavation rather than anchoring the wall itself.
Which earth retention system is right depends on the loads it must support, soil conditions, wall design, site access and other project requirements.
