Anchors

Anchors are stabilization and support elements that transfer tension loads using high-strength steel bars or steel strand tendons. A full-length hole is drilled through the soil and into the bond zone in the soil or rock using casing if necessary. Thread-bar, or strand tendon, is inserted into the hole and the hole is filled with high-strength grout and any casing used is then extracted. The length of the bar or strand above the bond zone is covered by a bond breaker to eliminate the load transfer above the bond zone. The anchor head is then generally tensioned and connected to the structure requiring the support.
