Estudio geotécnico in Las Navas de la Concepción

In Las Navas de la Concepción, the predominant ground consists of slates and schists, representing more than half of the underlying surface, followed by sandstones and conglomerates in a lower proportion. These materials generally exhibit low permeability and stable structural behaviour, providing good bearing capacity and making it easier to select shallow direct foundations in most cases. The occasional presence of water masses and loose soils such as fine sands or silts requires localised attention, as these can affect the ground’s moisture content and surface stability.

With regard to geotechnical risks, seismicity is very low, with a single event in the last three decades and a maximum magnitude of 3.1, so it does not represent a relevant constraint for structural design. There is no development of karstification in the area and, as it is a non-clayey substratum, the risk of expansivity is ruled out. In this way, the main aspect to be considered in the geotechnical study will be the local heterogeneity of materials and the possible presence of low-competence soils associated with areas of surface water.
