Estudio geotécnico in Torredembarra

In Torredembarra, compact gravels and sands predominate, representing the ideal base for shallow (direct) foundations owing to their high bearing capacity and good mechanical performance. Fine sands and silts, together with the limestone, dolomite and marble formations, appear occasionally and may imply variability in ground behaviour, although without posing major challenges in terms of stability, except in localised areas. Deltaic muds and peats, present only sporadically, should not be used as a foundation support level due to their high compressibility and low strength; therefore, it is essential to avoid these horizons during the design phase.

The seismic activity recorded in the area is very limited, with only three low-magnitude events in the last thirty years, which rules out seismicity as a relevant conditioning factor for the geotechnical study. The substratum presents no risk of expansivity, as no expansive clay layers are identified. Therefore, the main geotechnical consideration in Torredembarra is to identify and avoid the influence of saturated organic soils, giving priority to areas of compact gravels and sands as support for the foundations.
