Project Description

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.

Project Data:

  • Investment: USD 312 millons
  • Power generation: 160,4 MW
  • Length of the dam: 480 meters
  • Concrete used to build the dam: 225.000 cubic meters
  • Shotcrete: 55.000 cubic meters
  • The dam was built for aluvional defense, potable and irrigation water and power generation
