Due to the rock falls and possible overturning on bottom drainage valves booths, a stabilization of the existing slope is needed in Canales reservoir. Before the start of drilling, shotcreting with dramix is realised on the affected area to avoid possible material falls on workers. Later, steel bar gewi type passive anchors with a diameter of 50 mm are implemented in a 3x3 meters grid executed perpendicularly to the fracture planes so as to support these blocks. The anchors will realise a virtually cutting work.
