Estudio geotécnico in Palma de Gandía

In Palma de Gandía, the geological substrate is dominated by limestones, dolomites and marbles, accompanied by significant proportions of fine sands and silts. These materials generally provide a good bearing capacity for construction, although the local presence of gypsum, anhydrite and salts introduces risks associated with dissolution in contact with water, an aspect that is critical for foundation design. Given the low occurrence of clays and hard marls, the problem of differential settlements due to soft soils is limited, and the low permeability of the materials restricts the circulation of groundwater, except in small shallow aquifers.

Seismicity in the municipality is very low, with barely a recorded event every 30 years and smaller magnitudes, so the setting does not impose significant restrictions with regard to the seismic design of structures. Nevertheless, the existence of karst processes associated with the calcareous substrate requires an exhaustive prior assessment of possible cavities, as these may compromise the stability of the foundation. The main constraint in Palma de Gandía is therefore the potential presence of karst, which must be specifically evaluated in any geotechnical study prior to construction.
