Estudio geotécnico in Molvízar

In Molvízar, the dominant geological substrate is mainly composed of slates and schists, occurring in 95,84% of the local soils. These formations, characterised by low permeability, generally provide sufficient bearing capacity for shallow foundations, except in areas with intense weathering or near-surface fracturing, where it is advisable to carry out a specific analysis of the degree of alteration. The platy structure of slates and schists requires precautions in excavations and slopes, and it is common to find some variability in the mechanical response depending on the orientation of the foliation.

Within the municipality, seismic activity is very low, with only 7 recorded events over the last 30 years and a maximum magnitude of 2,4, which implies that seismicity is not a relevant constraint for design. As the substrate is not clayey, the risk of expansivity is ruled out. However, since this is an area with potential for karstification to develop, it is essential to check for the presence of cavities or processes linked to karst before executing any foundation. Thus, the most determining factor in the viability and safety of foundations in Molvízar will be the possible karst influence on the stability and uniformity of the ground.
