DYWIDAG Bar Anchor Systems are used in a wide variety of geotechnical applications. The principal fields of application include the stabilization of slopes and excavations as well as the counteraction of uplift forces.

The Principle:

DYWIDAG THREADBAR ® Anchors are used both in permanent and temporary applications.

Continuously threaded steel is used as a tendon for permanent and temporary anchors.

Permanent DYWIDAG THREADBAR ® Anchors are mainly used for slope stabilization.

Temporary DYWIDAG THREADBAR ® Anchors are mainly used for tying back excavation walls.

Thanks to their excellent load capacity and versatility, DYWIDAG THREADBAR ® Anchors can be easily and economically used in a wide variety of geotechnical applications.

The Characteristics:

  • Ease of system handling
