Geotechnical study in Aldaia

In Aldaia, the near-surface ground consists fundamentally of fine sands and silts, which determines a moderate bearing capacity and requires special attention to ground compaction for foundation projects. The aquifers, of a highly permeable nature, facilitate good drainage but may require control measures in the event of deep excavations. Compact gravel and sand, as well as hard clays and marls, appear only very scarcely, so they generally do not condition the choice of the foundation system except in specific cases.

Seismicity in Aldaia is classified as moderate, with 27 events recorded over the last 30 years, but with a maximum magnitude of 3.4, which does not impose any special structural requirements. The absence of relevant clayey soils eliminates the risk of swelling due to the non-clayey nature of the ground. There are also no karst risks in the area. In short, the predominant factor for the geotechnical study in Aldaia is the control of permeability and the variability of the particle-size distribution of the materials, for the correct selection of the foundation and protection against possible movements of groundwater.
