Estudio geotécnico in El Coronil

In El Coronil, the subsoil is dominated by formations of limestones, dolomites and marbles, materials which make up the entirety of the soils found in the area. These types of rock usually provide good bearing capacity for shallow and deep foundations, provided they are not altered and do not contain loose backfill, and they favour adequate stability of the works. Load transfer is facilitated by the cohesive, dense nature of these materials, although the presence of extensive but discontinuous aquifers may require specific studies to determine the groundwater level in each plot.

Seismicity in El Coronil is very low, with only one reported event in the last 30 years and a maximum magnitude of M1.7, ruling out the need for seismic requirements in structural design. However, the main factor to consider in the area lies in the presence of predominant expansive clays or areas documented as having problems with expansivity, which implies a clear risk of differential movements that may affect the integrity of the foundations. Therefore, thorough control and characterisation of the soils’ expansive potential should be the central focus of any geotechnical study in this municipality.
