The anchors are structural elements which are capable of transmitting stress to the ground by means of steel strand wires and various anchoring devices. These consist in a particular application of prestress in the field of civil engineering and their most common applications can be found in the anchoring of sheet piles, secant piles, diaphragm walls as well as other panels and floors subject to hydrostatic pressure.

The anchor is essentially made up of three parts: Anchor head, free part and bonded or foundation part.
