Estudio geotécnico in Alzira

In Alzira, fine sands and silts predominate as the most frequent soil types, accompanied by formations of limestone, dolomites and marbles present in a significant part of the municipality. This lithological set generally favours a bearing capacity that is adequate for shallow foundations, although the local presence of gravels and compact sands may allow even simpler solutions due to their greater compactness. The scarce occurrences of expansive clays and hard marls imply a low risk of expansion-related problems, while the limited permeability of most materials implies the possibility of shallow aquifers at localised points.

Seismicity in the area is notable, with 64 events in the last 30 years and a recorded maximum magnitude of 3.4; this level of activity requires moderate attention to dynamic aspects in structural design, although the recorded maximum magnitude does not oblige extreme measures. It is also essential to check the possible existence of karstification processes in the areas with limestone and dolomites, as these condition the safety and stability of the foundations. The main factor to consider in Alzira is the presence of karstic ground and lithological variability, which makes it necessary to carry out detailed geotechnical study campaigns before executing any foundation.
