Estudio geotécnico in Arjonilla

In Arjonilla, formations of limestones, dolomites and marbles predominate, providing a competent and stable substrate for construction. Local infills of fine sands and silts occur only occasionally, and hard clays or marls are fairly rare in the area. The high prevalence of carbonated materials usually ensures excellent bearing capacity, facilitating the design of shallow foundations in most cases, although it is recommended that a specific geotechnical study be carried out to verify homogeneity and the location of any potentially loose areas or materials with low strength.

Seismic activity in Arjonilla is very low, with a maximum of three events over 30 years and a maximum magnitude of 2.3, so seismicity does not represent a relevant constraint for structural design. In addition, the composition of the substrate rules out expansivity-related risks associated with clays. These factors place the main geotechnical focus on identifying areas with specific sands or silts, which must be characterised in detail in order to size the foundation correctly.
