Estudio geotécnico in Hornachuelos

In Hornachuelos, soils formed by slates and schists predominate, providing a competent substrate, albeit with low to very low permeability. These materials usually offer a good bearing capacity for traditional shallow foundations, although they may require specialised excavations if very fractured layers are encountered. The occasional presence of levels of limestones, dolomites and marbles introduces the possibility of finding localised areas that are stiffer, whereas fine sands and silts are restricted to minimal percentages and generally do not constitute the main support level.

With regard to geotechnical risks, seismicity is moderate, with 24 events over 30 years and a maximum magnitude of 3.5, so the setting does not impose major seismic constraints on current structural projects. It is relevant to consider the possible presence of karst associated with limestones and dolomites, as this can develop voids that must be verified in detail before any foundation is executed in those areas. The non-clayey substrate rules out the risk of expansivity; therefore, the main focus should be on checking for the karst phenomenon wherever carbonate levels are detected.
