Estudio geotécnico in Almacelles

In Almacelles, the dominant substrate is mainly composed of sandstones, conglomerates and flysch, accounting for around 71% of the ground present in the municipality. These materials, together with the secondary presence of compact gravels and sands, generally provide a good bearing capacity and favourable conditions for shallow foundation, with the low permeability of most of these formations being a relevant factor for the design of drainage and moisture control. Fine sands, silts and hard clays/marl appear only infrequently, so their influence is limited in the overall context of the geotechnical study, although it is recommended that they be identified in situ in order to avoid foundations on compressible or non-homogeneous horizons.

Seismicity in Almacelles is very low, with only three events in the last thirty years and a maximum magnitude of 2.5, which implies seismic risks that are practically negligible for structural design purposes. There are no karst phenomena in the area, and any potentially expansive clays appear only subordinately or within climatic settings of low risk, reducing the likelihood of significant volumetric movements. Therefore, in this municipality, the main constraint to be taken into account in the geotechnical study lies above all in the accurate identification of the bearing horizons and in controlling soil permeability to prevent problems associated with groundwater.
