Anchors

Retaining structures without a tie-back? Almost unconceivable today. Since we invented it in 1958, the ground anchor has provided a technically elegant yet economical and commercially attractive structural engineering solution. Achievable in all types of soil including rock – whether temporary or permanent – excavation pits without obstructive struts have been a matter of course since then. With our many years of experience, we guarantee flawless technical implementation.

Temporary anchors

Grouted anchors for temporary applications

Temporary anchors – as bar anchors or strand anchors, fully or partially reconvertible – are used to safeguard retaining walls for a period of two years at most. The bearing behavior of each grouted anchor is tested and recorded during the acceptance process. Strand anchors can also be used in tight spatial conditions. 

Permanent anchors

Grouted anchors as permanent anchoring systems

Permanent anchors are used for a period of more than two years and are thus part of a permanent structure. They are designed as permanent strand anchors or single-rod corrugated tube anchors. The steel tendon and anchor head are protected against corrosion, each cavity of the anchor head is filled with permanently plastic corrosion-proof compound.
