Estudio geotécnico in Puig-reig

In Puig-reig, the predominant geological substrate is formed by sandstones, conglomerates and flysch. These materials exhibit low permeability at the surface and usually make up extensive formations, which in general ensures adequate bearing capacity for building work. However, the occasional presence of subordinate layers of expansive clays requires checking the exact location of the foundations in order to avoid potentially problematic areas, although the overall risk of expansivity is low due to their subordinate nature and local climatic conditions.

Seismic activity in the municipality is very low, with a single recorded event of low magnitude (Mmax 1.5) over the last 30 years, so seismicity does not represent a relevant limiting factor for structural design. No karstification phenomena associated with this geological context exist either. The main geotechnical constraint for projects in Puig-reig is the point identification of expansive clays and the specific analysis of the stratigraphic profile, ensuring foundation safety on the most competent materials.
