Estudio geotécnico in Benissanó

In the municipality of Benissanó, soils formed by limestones, dolomites and marbles predominate, which implies the presence of a bedrock substrate with a high bearing capacity, suitable for robust shallow foundations provided that the excavation level remains over sound, unaltered matrix. The occasional presence of fine sands and silts introduces local variability where bearing capacity may be lower, requiring a specific analysis of the stratigraphy before defining the type of foundation. The associated soils act as very permeable aquifers, which can influence drainage positively but requires control during the execution of deep foundations.

Seismicity in Benissanó is considered moderate, with 27 events over 30 years and a maximum magnitude below 4.5, so the usual structural seismic requirements will be sufficient in most cases. It is essential to verify the presence of karst in the calcareous substrate before founding, as cavities or voids may affect the stability of the structure. Although expansive clays occur in a subordinate arrangement or in climatic zones without water deficit, their influence is usually secondary given the predominance of carbonate materials. The main geotechnical constraint, therefore, is the characterisation and recognition of karst, prioritising an exhaustive ground investigation before any foundation design.
