Estudio geotécnico in Riudecanyes

In Riudecanyes, shales and schists predominate as the substrate, accompanied to a lesser extent by granite, gneiss and other igneous materials. These metamorphic and igneous rocks habitually provide a high and stable bearing capacity, which makes it easier to select direct or shallow foundation solutions. Fine sands and silts occur only occasionally and do not, as a whole, represent problematic typologies for the municipality regarding the installation of foundations, except in specific cases where it will be necessary to analyse the possibility of differential settlements.

The seismicity recorded in Riudecanyes is very low, with only five events over thirty years and a maximum magnitude of 1.8, which implies an almost negligible seismic risk for structural design. However, since the area shows karstification, it is recommended to thoroughly verify the presence of karstic cavities before carrying out the foundation, as they could affect ground stability. Thus, the main geotechnical consideration in this setting is the possible occurrence of karst processes, whereas the risk of expansivity is ruled out thanks to the dominant non-clayey substrate.
