Estudio geotécnico in Sant Vicent del Raspeig/San Vicente del Raspeig

In Sant Vicent del Raspeig/San Vicente del Raspeig, sandstones, conglomerates and flysch predominate as the geotechnical substrate, providing a firm foundation for shallow foundations and ensuring adequate bearing capacity for domestic and industrial buildings. In a complementary way, limestones, dolomites and marbles appear, together with occasional lenses of fine sands, silts and compact gravels. The very scarce presence of clayey materials and the low frequency of soils containing gypsum or salts generally indicate ground conditions suitable for direct foundations. However, it is recommended to analyse the possible point presence of gypsum, anhydrite and salts due to the risk of dissolution, which may affect the durability of the foundation in specific areas.

The municipality is characterised by very low seismicity, with only two events in the last 30 years and a low maximum magnitude (Mmax 2.1), so seismic risk is not a relevant constraint for structural design. The non-clayey substrate rules out concern about expansivity in the soils. Given the proportion of limestones and dolomites, the potential existence of karst must be verified thoroughly before carrying out any foundation works, as this is the main aspect for control in the geotechnical analysis of the ground for projects in Sant Vicent del Raspeig.
