Santa Juana Dam with the height of 103m in Chile was constructed with alluvial materials on the sandy gravel layer and first adopted an integrated anti-seepage system among the dams higher than 100 m. In the system, a linkage plate was used to connect the underground concrete wall and the plinth. The good anti-seepage performance of the project proved the effectiveness of the integrated anti-seepage system, which set a good example for the following dam construction. Santa Juana Dam was completed in Dec. 1995 and has been in good performance up to now.

The project is owned by Chile Public Works Ministry.
