Estudio geotécnico in Riosa

In the municipality of Riosa, geological formations of limestones, dolomites and marbles predominate, which implies the habitual presence of highly compact and resilient carbonate rocks. These materials provide appreciable bearing capacity for foundations and generally exhibit low permeability, although they may host shallow aquifers under certain conditions. The scant presence of clays and hard marls minimises the likelihood of problems associated with soft soils, facilitating the design of direct foundations on the compact bedrock.

Seismicity expected in the area is very low, with only 6 recorded events over 30 years and a maximum magnitude (Mmax) of 2.6, which allows the significant seismic influence on construction projects to be ruled out. However, given the dominant limestone nature, it is essential to carry out an exhaustive investigation to rule out or confirm the presence of karstic cavities, which can seriously affect foundation stability. As this is not an clayey substrate, the risk of expansiveness is ruled out, and the potential occurrence of karstic processes is the main local geotechnical constraint.
