Estudio geotécnico in Corral de Almaguer

In Corral de Almaguer, sandstones, conglomerates and flysch predominate, accompanied in significant frequency by gypsum, anhydrite, salts and limestones. This combination forms a subsoil with low to medium bearing capacity depending on the compaction and the degree of alteration. Carbonate formations such as limestones and dolomites also stand out, as they favour shallow foundations on competent rock in localised areas. However, the considerable presence of gypsum, anhydrite and salts may induce dissolution phenomena, which implies the need for a detailed analysis in order to choose the safest and most durable foundation type.

Seismic activity in the area is moderate, with 11 recorded events over 30 years and a maximum magnitude of 3,9, which implies considering moderate seismic loads in new-build projects in accordance with the current regulations, although without reaching severe conditioning factors. It is relevant that the subsoil has non-clayey characteristics, ruling out expansivity risks. However, due to the frequent presence of materials susceptible to the development of karstic phenomena, it is essential to carry out specific checks on ground stability before constructing foundations; this is the main geotechnical constraint in the locality.
