Geotechnical study in L'Ametlla de Mar

In L'Ametlla de Mar, soils of calcareous nature predominate, including limestones, dolomites and marbles, together with significant areas of compact gravels and sands. This composition generally provides a high bearing capacity, facilitating the adoption of shallow, direct foundations in most cases. Good foundation performance is supported by the high degree of compactness and permeability of these materials, although attention is recommended regarding the possible presence of voids in carbonate areas.

Seismicity in the area is moderate, with a record of 30 events over 30 years but with a maximum magnitude of 2.5, which does not imply strict structural requirements, although it should always be taken into account when making decisions. The absence of clayey substrata eliminates risks of expansivity. However, given the karstifiable nature of the limestone and dolomitic formations, it is essential to verify any possible cavities before carrying out the foundation; this is the most relevant technical constraint for the geotechnical studies in the locality.
