Estudio geotécnico in Carcaboso

In the municipality of Carcaboso, granite and gneiss predominate as the substrate alongside other igneous rocks, which ensure a notable bearing capacity for the foundations of buildings. Sandstones and conglomerates appear only occasionally, but the widespread presence of shallow aquifers between these formations and the low permeability of the ground are factors to take into account, particularly with regard to the drainage design and possible seepage. Phyllites and schists are infrequent, so they generally do not significantly affect the overall approach to foundations.

Seismicity in Carcaboso is significant, with 56 events in the last 30 years, although the maximum recorded magnitude (Mmax 3.1) remains at moderate levels for the area. No signs of karst processes are evident, and since the substrate is mainly non-clayey, the risk of soil expansivity is ruled out. The main geotechnical constraint lies in the low permeability and possible localised aquifers, which require special attention in the design of foundations and moisture-control systems on site.
