Estudio geotécnico in Cacabelos

In Cacabelos, the dominant ground consists of sandstones, conglomerates and flysch—materials that provide good bearing capacity for conventional foundations. Complementarily, the occasional presence of compact gravels and sands favours optimal conditions for load transfer. The shales and schists, although present, do not usually pose serious complications for residential or light foundations and, as the substratum is non-clayey, the risk of expansiveness is ruled out. Water bodies and deposits of fine sands and silts occur residually and must be analysed on a case-by-case basis in geotechnical studies, particularly if construction is planned in their vicinity.

Seismicity in Cacabelos is very low, with a single recorded event every 30 years of low magnitude (Mmax 1.7), so this parameter does not represent a relevant limitation in structural design. Since no karst phenomena or risk of expansive soils are reported, the main constraint to consider in the geotechnical study will be lithological heterogeneity, especially in projects that require deep excavations or are located close to areas of surface water.
