Estudio geotécnico in Malgrat de Mar

In Malgrat de Mar, the subsoil is composed mainly of fine sands and silts, as well as compact gravels and sands, with a secondary presence of granite, gneiss and schists. The predominance of these materials implies generally adequate bearing capacity, although in areas with sands and silts soil compaction or improvement may be necessary to achieve the stability required for the foundations. The granite and gneiss formations, which are frequently present, provide a robust base for supporting structures, while the schists, although less common, may require localised studies to assess their suitability.

As for the conditioning factors, seismicity in Malgrat de Mar is very low, with only a single registered event in the last three decades and a very low maximum magnitude, which minimises this aspect in structural design. The subsoil presents no risk of expansiveness, as the substrate is not clayey, and there are no indications of karstification. The main technical aspect to consider in the geotechnical study will be the detailed characterisation of the sandy and silty layers, to ensure stable foundations and control potential differential settlements in areas of contact with more competent materials.
