The project consist in an earth dam with 1.300 hectare of reservoir, 116 meters high, with a central impermeable core, where the tunnel work was emphasized. The deviation tunnels and the adduction tunnels, which were 15 km long, with different diameters, were totally shotcreted with Sigunit-L22 (1.100 tons), using a robot arm. Shotcrete was also used in the hillside where we have provided with two Aliva -246 machines.
