Geotechnical study in Algímia d'Alfara

In Algímia d'Alfara, the predominant geological substratum consists of limestones, dolomites and marbles, materials with a high mechanical performance and good bearing capacity for shallow and deep foundations. To a lesser extent, sandstones, conglomerates and granular soils may occur, as well as deposits of fine sands and silts; however, the presence of hard clays is residual and the incidence of mud or peat is practically negligible. These factors favour the overall stability of the ground and enable versatile foundation solutions, tailored to the strength of the carbonated rocks and compact soils.

The recorded seismic activity is very low, with only two events in 30 years and a maximum magnitude of less than 2, which minimises the influence of seismicity on structural calculations. Although the substratum is not clayey, so the risk of expansive behaviour can be ruled out, the karstified nature of the limestones and dolomites makes it necessary to carry out a specific karst verification before executing any foundation. Control of cavities and voids will be the main technical constraint in the geotechnical studies for the area.
