Estudio geotécnico in Caldas de Reis

In Caldas de Reis, a substrate made up of sandstones, conglomerates and flysch predominates, accounting for more than 60% of the territory, which provides a generally competent base suitable for receiving structural loads. Areas with fine sands and silts, although less frequent, may show some compressibility and lower bearing capacity; in these cases, a detailed analysis will therefore be recommended to avoid differential settlement. Additionally, the presence of slates and schists in certain sectors may involve local variability in ground resistance, although overall the municipality lacks relevant low-consistency materials that would seriously condition foundation options.

The level of seismic activity in Caldas de Reis is very low, with only three events in thirty years and a maximum recorded magnitude of 2.1, ruling out seismicity as a relevant constraint for structural design. On the other hand, the non-clayey substrate eliminates the risk of expansiveness, allowing greater confidence in selecting foundation systems. In conclusion, the main focus should be on identifying local lithology changes and, in the case of areas with sands or silts, carrying out targeted studies to ensure the suitability of the support, since the other geotechnical factors do not present significant risks in the municipality.
