Estudio geotécnico in Los Corrales

In the municipality of Los Corrales, the substrate is dominated by sandstones, conglomerates and flysch, present in more than 90% of the area, followed secondarily by gravel and compact sands. These materials generally exhibit good bearing capacity, which favours the use of shallow direct foundations, although the compactness and continuity of the load-bearing layers must be confirmed at each specific site. It is important to consider that the permeability of these materials is low at the surface but they may host aquifers at greater depths; therefore, it is recommended to assess possible variations in the groundwater table level in order to avoid impacts on the foundation design.

Seismicity in Los Corrales is very low, as shown by a single event over 30 years and a maximum magnitude of 1.7, so it does not constitute a relevant constraint for structural design. However, it should be noted the local presence of expansive clays, especially in certain climatic zones, which implies a potential risk of ground swelling and shrinkage. This factor can notably affect the stability of the structure, so it is essential to investigate its distribution and depth before defining the foundation; this is the main geotechnical constraint in the area.
