Quimbo Hydroelectric Plant
Potrerillos, Gigante, Huila, Colombia
The “El Quimbo” hydroelectric power plant 250 km (170 miles) south-west of Bogota is located on Colombia’s main river, the Rio Magdalena. The facility features a 160-meter (525 feet) tall and 700-meter (2,300 feet) wide main dam, a 66-meter (216 feet) tall and 400-meter (1,312 feet) long secondary dam and a 400MW power station. The new artificial basin created is the largest in Colombia and forms a 55-km (34 miles) long reservoir of over 8,000 hectares (19,770 acres).
After casting a total of 250,000 m3 (327,000 cubic yards) of concrete, cracks had formed on the spillway at El Quimbo due to aggressive temperature changes. These cracks were a concern for the developers in regards to the durability and operation of the plant with a service life of 50 years. Subsequently, a total area of almost 14,000 m2 (150,695 square feet) of the spillway was treated with the PENETRON repair system to the full satisfaction of the client.
