Estudio geotécnico in Santo Tomé

In Santo Tomé, the predominant soils are limestones, dolomites and marbles, which make up more than 80% of the substrate and present themselves as competent materials for foundations due to their high bearing capacity. However, these materials may exhibit significant fracturing and, in some areas, certain limestone units can develop shallow aquifers. Sandstones, conglomerates and flysch are considered infrequent, and due to their low presence, they rarely condition the design of foundations.

Seismic activity in the municipality is very low, with only 5 events in the last 30 years and a low maximum magnitude, which minimises structural concerns related to seismicity. Nevertheless, given the karstic features of the dominant materials, the possible presence of cavities and underground conduits must be investigated in any geotechnical study prior to the execution of foundations. The non-clayey substrate rules out expansivity risks, so the main geotechnical constraint lies in verifying and characterising the karst before any construction intervention.
