Estudio geotécnico in Coreses

In the municipality of Coreses, granular materials predominate as the substrate, mainly compact gravels and sands, accompanied by lithic formations such as sandstones, conglomerates and flysch. These soils generally offer a high bearing capacity, which usually allows the execution of shallow direct foundations, particularly in areas where the sandy and gravelly deposits exhibit an adequate degree of compaction. Slates, schists and some limestones, present in smaller proportions, may require specific checks for strength and uniformity if they are encountered during the geotechnical study.

With regard to natural hazards, the area of Coreses presents a high level of seismicity, with 200 events recorded over 30 years and a maximum magnitude of 4.5, which makes it necessary to take this factor into account in structural design and in the type of foundation recommended in the geotechnical report. There is no problem relating to karstification and, given that the substrate is mostly non-clayey, the existence of risks arising from expansive soils is ruled out. Thus, the main geotechnical constraint in Coreses is seismicity, which must be considered as a priority in building and civil engineering projects in the locality.
