On the maintenance carried out by OCENSA for slope stabilization in areas with geotechnical issues, protection of lateral streams’ banks, maintenance of the Right of Way (RoW) embankment or access roads, sheet piles have been successfully used. The paper describes the different alternatives and their uses. Among them are: terraces to facilitate drainage and plant recovery, PVC sheet piles for protection of stream banks, sheet piles made of carbon steel pipe and steel deck in which the piles can be driven by percussion or previously excavated with drilling machine.

Usually, the definition of geotechnically homogeneous zones is established through the analysis of information on a regional (and even national) scale of those characteristics that define the topographic, geological, climatic, and land use conditions by categorizing them and applying algorithms of interaction between these variables. However, in technical literature and in technical reports of state entities that manage natural hazards, new advances are being made in the determination of other aspects or variables that detail the condition of geotechnical susceptibility; at the same time, nowadays there are technological tools for the massive analysis of information and its spatialization. This article presents a new approach to the definition of geotechnically homogeneous zones using these technological tools. A comparison is made against the conventional definition.
