Perforations and attaching bar bolts

Attaching bar bolts or anchors, whether active or inactive, is a method for holding up and reinforcing meshes. Its purpose is to prevent big landslides and it is done by means of stitching a mass of rock with fissures and securing individual blocks and large masses in general.

The absolute interior of the bar is attached to healthy and stable rock with the injection of grout to form a bulb and, the absolute exterior is attached to the distribution plate and the female coupling, thereby fixing the unstable mass of rock.
