USE OF GEOSYNTHETICS IN LAUTARO DAM

The Lautaro reservoir is a 30 m high and 42 million m3 capacity earth dam. In an observation boring, pressures higher than 3 m water column above the ground level were measured at the downstream toe of the dam. The solution was a system of filter, drain and overburden. Taking into account the ground conditions, costs and other technical requirements, the best solution for the filter was a geotextile. The works were carried out and the filtrations now flow without any risk for the dam.
