Estudio geotécnico in Les Masies de Voltregà

The subsoil of Les Masies de Voltregà is composed mostly of sandstones, conglomerates and flysch, materials that are recurrently present in the area. Owing to their lithological nature, these soil types generally provide a notable bearing capacity and are suitable for the direct support of conventional shallow foundations. However, the low permeability of these formations means that it is necessary to consider the drainage behaviour and the occasional presence of shallow aquifers, especially in areas with seasonal water input.

In terms of seismic hazard, Les Masies de Voltregà records very low seismicity, with only 5 events registered in the last 30 years and a maximum magnitude of 1.6, so the associated risk is practically negligible in the context of structural design. Since the dominant substrate is not clayey, the risk of expansivity is ruled out, which simplifies the foundation design and execution process by removing the need for special measures associated with expansive soils.
