Estudio geotécnico in Càlig

In Càlig, the subsoil is dominated by the presence of limestones, dolomites and marbles, which ensures in most cases a high bearing capacity and stable conditions for shallow or deep foundations. However, the complementary presence of fine sands, silts and the low frequency of gravel and compact sands introduces local variability, which may require an adjustment in the depth or type of foundation depending on the stratigraphic level in which each material is identified. The characteristically low permeability of these lithological formations, combined with the possible existence at depth of aquifers, recommends a detailed analysis in the project phases.

The seismic activity recorded in Càlig is very low, with only 1 relevant event in the last 30 years and a maximum magnitude of 1.6, which results in minimal seismic requirements for structural design. However, the main geotechnical constraint in the area is the presence of karstification features, typical of carbonate environments. Prior to the design and execution of the foundation, it is essential to verify the absence of voids or dissolutions that could affect the building’s stability. Expansive clays appear subordinately or in low-activity climatic contexts, which minimises their impact in most cases.
