Estudio geotécnico in Quesada

In Quesada, the predominant ground is formed mainly by limestones, dolomites and marbles, accompanied in smaller proportions by sandstones, conglomerates and flysch. These materials generally offer a good bearing capacity, which is favourable for direct foundations, especially where compact materials crop out. However, the presence of granular materials such as compact gravels and sands is uncommon, as are fine sands and silts, whose low proportions limit their impact on the overall stability of the subsoil. The predominance of moderate aquifers suggests acceptable permeability, but it is essential to assess the degree of saturation and possible hydrogeological variations depending on depth.

Quesada is located in an area with notable seismicity, with 56 events over 30 years and a maximum recorded magnitude of 4.4, so seismic action must be taken into account in the structural design of new buildings. In addition, the karstic nature of the prevailing materials makes it necessary to verify the existence of cavities or dissolutions before founding, as these phenomena can significantly affect the stability of structures. As no clayey subsoils are found, the risk of expansivity is ruled out. The main factor conditioning construction projects in Quesada will be the appropriate characterisation of the karst and the local seismic response.
