Estudio geotécnico in Massalfassar

In the municipality of Massalfassar, the most common substrate is made up of compact gravels and sands, present in more than 80% of cases, standing out for their excellent bearing capacity, which significantly simplifies foundation options for buildings and civil works. Although areas with white expansive and soft clays are also recorded occasionally, the predominance of granular materials contributes to high strength and stability, and enables rapid drainage thanks to the high permeability associated with extensive and productive aquifers. Therefore, the usual shallow foundation procedures are entirely feasible in most of this geotechnical environment.

With regard to seismic hazard, statistics indicate moderate seismicity, with 27 events recorded over the last 30 years and a maximum magnitude (Mmax) of 3.4, a figure that does not require any special considerations in structural design beyond the usual regulatory parameters. The expansivity analysis concludes that the predominant substrate is not clayey, so the presence of significant geotechnical risks associated with expansivity is ruled out. The main geotechnical constraint in Massalfassar is to ensure compatibility between the high soil permeability and aquifer protection during the execution of the foundations.
