Completed in 1998, the dam is 100 meters (330-feet) high and 442 meters (1,460-feet) wide and has a reservoir capacity of 327 million m³ (86 billion gallons) of water, making the Jucazinho Dam the largest reservoir in Pernambuco.
To seal the cracks and eliminate the surface scaling, the concrete walls were treated with a combination of PENETRON INJECT FLEX, a spray applied liquid sealer, PENESEAL PRO and PATCHLINE SM, a polymer-modified mortar. PENETRON INJECT FLEX, a resin injection, was used to seal 6,000 m (20,000-feet) of concrete joints. PATCHLINE SM was applied to over 20,000 m2 (220,000-square feet) of dam walls at a thickness of 2 cm. PENETRON ADMIX was added to the shotcrete to improve the concrete performance and waterproof the drainage galleries.
