Perforations are made 2 meters deep in the rock mass and steel rods are introduced into the perforations. Subsequently the drilling is filled with concrete mix. It is then proceeded to the placement of the courses of jets, the placement of the sanitation pipes and the mechinales of the jetty. Finally, the space between the set course and the rock slope is concreted.
The concrete blocks are prefabricated by molds by placing stone from the plot itself at the bottom of these and then filling with concrete. Each block has a steel clip on the back where to tie a steel cable during placement. Once unmold and cleaned, the blocks are transported to the plot. Perforations of two meters deep in the slope are executed and corrugated rods are introduced. Meanwhile, a concrete base is executed on which the first course is placed. Finally, the cables that tie the blocks to the rods anchored to the rock mass are placed and tensioned and the trasdos are filled.
