Estudio geotécnico in Tomares

In the municipality of Tomares, the geological substrate is dominated by the presence of water-bearing masses and a significant proportion of carbonate materials such as limestones, dolomites and marbles, together with occasional occurrences of fine sands and silts. This composition confers generally adequate bearing capacity; however, in areas where sands and silts outcrop, it is important to assess their compactness and possible susceptibility to settlement. The dominant presence of local and discontinuous aquifers indicates moderate permeability, which may require special attention to the management of groundwater levels and drainage in foundation projects.

Seismicity in Tomares is very low, with hardly any events occurring every 30 years and a maximum recorded magnitude of 1.7, so it does not represent a relevant constraint for structural design. No karstification has been reported in the surrounding area, which minimises risks associated with underground voids. However, the presence of non-expansive or dispersed clays in a non-clayey matrix is detected, implying some risk of expansivity that must be verified through specific testing during the geotechnical study campaign. This aspect is the main constraint for ground characterisation and for selecting the most recommended foundation type in the area.
