In order to solve problems related to the instability of natural slopes or hillsides, diverse techniques in terrain treatment have been employed: jet-grouting, micropiles, wall or anchored piles, etc. Amongst these systems, the use of more or less rigid inclusions, with or without anchors and introduced on both sides of the fracture surface, can be distinguished. This paper describes the possibilities of the use of resistant, discontinuous "buttresses" to increase the stability of the embankments on the natural slopes analysed. These "buttresses" can be formed by close reinforced injections up to pile rectangular modules (5 × 1 m, plan view). Real examples of the application of these "buttresses" with differing rigidities are included.
