Estudio geotécnico in San Sadurniño

In San Sadurniño, the ground is dominated by outcrops of slates and schists, followed in smaller proportions by granite, gneiss and other igneous rocks. These materials, characterised by their low permeability, generally provide a firm base for foundations, ensuring good bearing capacity. However, it is important to take into account the possible local presence of fine sands and silts, although these are infrequent and require special attention to avoid differential settlements.

Seismic activity in the municipality is very low, with a single minor recorded event over the last three decades and a maximum magnitude of 2.2, practically ruling out seismic risk for structural design. In addition, the non-clayey substratum eliminates risks of expansivity associated with clays. In conclusion, the main geotechnical consideration for San Sadurniño lies in the local assessment of the continuity and condition of the rock materials, since the low permeability and the absence of other limiting factors provide a stable environment for most foundation solutions.
