ENEL Hydroelectric Power Plant
Andonno (Cueno), Italy
ENEL is a global energy provider and Italy’s largest power company; the power plant in Andonno is one of the company’s most important. PENETRON products helped restore a 2km section of the main tunnel by waterproofing a total area of 24,000m2, including the joints and tunnel walls.
The tunnel walls were treated with PENETRON, which was applied by spray application. The joints and cracks were treated with PENECRETE MORTAR with an additional amount of PENETRON in liquid form that was injected by resin to ensure a deep penetration of the PENETRON crystals into the concrete structure where cracks had damaged the surface. This method ensures a further tightening of the concrete matrix, preventing water ingress through joints and cracks.
