A gravity concrete dam built 61 years ago in South America is diagnosed due to the cracking and signs of deterioration detected in the spillway and other elements. Besides the interest to identify the causes, the authorities are concerned by the structural effects on the concrete slab road bridge that is supported on the spillway. This road is one of the main routes for transportation of the country. A comprehensive diagnosis on the state of the dam is presented, including research of the historical documentation, visual inspection of the dam, performance of tests and numerical simulations. The case study is particularly interesting since several phenomena occur, including expansive reactions of different origin.
