Originally built in the 1920s, the concrete bridge spanning a small creek to supply a water power plant was in serious need of repair. Water leakage was reported in several areas of the bridge; sealing the structure against water penetration and to protect the embedded reinforcement steel from corrosion was a priority.
The water flow was stopped to repair the inside of the bridge and compromised concrete areas were renewed. The whole area was treated with two coats of PENETRON and the bridge was filled with water again. Within a few days all leaks were completely sealed.
