It consists on a rock curtain with a concrete surface, the body of the Dam is formed  with graduated materials that  support the concrete  surface formed with  panels of  15,0 m  height and variable thickness,  the concrete surface rests over the pedestal that also works as a platform to  make the injections of consolidation and i mpermeable screen  that alongside a  gallery  system excavated on both sides of the curtain’s engraved will form the stem plane.

The  concrete surface will have a system of  seals and cupper  joints and P. V. C.; that will be placed on all the joints of the concrete surface and on the perimeter  joint  of the  base-concrete  surface,  these  protections  should guarantee minimum filtrations.To measure these filtrations, a filtering gallery will  be placed on  the bottom of the curtain on downstream zone in order to be able to get all the filtrations that may occur on the body of the press and to be able to measure the filtering flow on any given time of the year
