Estudio geotécnico in Corvera de Asturias

In Corvera de Asturias, the dominant geological substrate is composed of phyllites and schists, materials that account for 21.02% of the area and that exhibit low permeability. The presence of urban anthropogenic infill is scarce and rarely affects the overall bearing capacity. These materials, thanks to their compactness and cohesion, provide good bearing-capacity conditions provided they do not show advanced weathering, and are usually suitable for conventional shallow foundations. However, local verification of the thickness and integrity of the infill is important to avoid differential settlements.

Seismicity in Corvera de Asturias is considered very low, with a recurrence of three events over 30 years and a maximum recorded magnitude of 2.3, which does not require special measures in structural design. Given the possible occurrence of karst environments, it is essential to carry out specific investigations to rule out the presence of cavities before executing any foundation. The absence of clayey substrates eliminates the risk of expansivity; the main geotechnical conditioning factor is the low permeability of the materials and the potential existence of karst zones.
