Tie Rods

DYWIDAG Threadbar™ systems can be adjusted with ease for use as versatile tie rods.

DYWIDAG Threadbar™ systems can transfer tensile forces and be used as tie rods. The systems can be adjusted on-site, independent of installation conditions or existing deviations or alterations.


The continuous thread on the DYWIDAG Threadbar™ means bars can be cut, anchored, and coupled at any point—and adjusted to requirements on-site. 

Tie rods are used in

  • The assembly of sheet pile harbor walls

  • Cross-linkings

  • The tie back of walls in deadman anchored structures

  • The positional stability of joint connections, corner joints, and foundations

How tie rods work

The continuous thread on the DYWIDAG Threadbar™—which allows bars to be cut, anchored, coupled at any point, and adjusted on-site—makes the system completely independent of installation conditions or existing deviations or alterations. 

Corrosion protection

Depending on requirements and steel grades, a variety of methods can be used to protect tie rods from corrosion:

  • Loss of cross-sectionial area—sacrificial corrosion

  • Galvanizing

  • Coal tar expoxy coating

  • Specialized Tape Wrapping

  • Double Corrosion Protection (DCP) for the highest protection


  • Different steel grades

  • Various corrosion protection systems are applicable

  • Comprehensive range of accessories for anchoring and coupling

  • The system can be easily, quickly and safely adjusted to on-site conditions

  • No limitation of installation tolerances

  • Prestressing for deformation minimization

  • Weldable bars and accessories
