Djerdap 1 (Iron Gate I) Hydroelectric Power Station is the largest dam on the Danube River, located in the Iron Gate Gorge on the Serbia-Romania border. At the time of its inauguration in 1972, the dam was the 10th largest hydroelectric power station in the world.
The facility is jointly operated by Serbia and Romania and has a total output of 10.89 TWh (5.24 TWh on the Serbian side and 5.65 TWh on the Romanian side) based on its generating equipment.
In 2008, renovation began on the 36-year old concrete structure on the Serbian side of the dam. After the failure of previously applied repair solutions, Penetron Hellas was invited to present the PENETRON System in early 2019. The product demonstrations showed that PENETRON INJECT could successfully solve issues of deeply embedded voids and honeycombs. Shortly thereafter, the PENETRON solution was approved for the project.
Subsequently, PENETRON was applied to several concrete elements and sections on the project, including the facility building, retaining walls, slabs, ceilings and columns. Several thousand square meters of concrete surface were treated with a PENETRON coating to seal the structure against further water ingress and prevent further deterioration.
PENEPLUG, PENECRETE and PENETRON slurry were applied to complete repairs on the water reservoirs and construction joints to permanently seal cracks and other concrete defects.
Thanks to the effectiveness of Penetron’s concrete repair and protection solution, the Iron Gate I project management team continues to rely on PENETRON for the ongoing repair works at the Danube River’s largest hydroelectric power station.
