TRB-02 permanent ground anchors are usually used in the construction of bulkheads and diaphragms, where the type of ground does not have any particular geo-technical problems and where permanent ground anchors are needed with the free length having a double protection.

The anchor is made as follows:

• In the active part, the bar is separated from the corrugated sheath by special spacers/centralizers arranged radially to the bar itself.
• The free length is protected by inserting a corrugated sheath in H.D.P.E. The separation of the free length from the active part is achieved by way of NBR rubber buffers, which allow both parts to be perfectly hermetic. A smooth external PVC sheath guarantees the sliding of the anchor free length during tensioning.
