Estudio geotécnico in Piñor

In the municipality of Piñor, the dominant geological substratum consists of sandstones, conglomerates and flysch, present in almost 60% of the territory. Slates and schists are also frequent, representing close to 39%. These materials generally provide a favourable bearing capacity for shallow foundations, although the local presence of fracturing or alteration could locally modify conditions. Given the generally low permeability of these formations, there are usually no relevant concerns regarding internal erosion or other risks associated with the migration of groundwater; however, it is advisable to check for the presence of shallow aquifers in specific areas of the municipality.

As regards seismic behaviour, Piñor exhibits very low seismicity, with only 3 recorded events in the last 30 years and a maximum magnitude of 2.7. This implies that structural seismic considerations do not represent a significant constraint in the design of buildings. In addition, the non-clayey substratum rules out risks of expansivity, reducing the likelihood of significant delayed movements or differential settlements. In this context, the main parameter to consider during the geotechnical study will be the accurate characterisation of the state of weathering and the identification of any possible local aquifers.
