Estudio geotécnico in Las Mesas

In Las Mesas, the subsurface is dominated by sandstones, conglomerates and flysch, forming ground with detrital and sedimentary lithology. These types of soil are usually characterised by their compactness and relative stability, which favours an overall acceptable bearing capacity for conventional buildings. However, the low near-surface permeability of these formations implies that, although the possibility of deep aquifers exists, the near-surface hydrogeotechnical behaviour remains almost impermeable, affecting the proper selection and design of the foundations.

Seismic activity in Las Mesas has a moderate impact, with 40 events recorded over thirty years and a maximum magnitude of 4.1, which makes it necessary to take certain seismic parameters into account in structural calculations, especially for special or unique buildings. There is no karst risk and no significant problems related to expansivity associated with the substrate are identified. Therefore, the main geotechnical constraint lies in the compactness of the strata and the appropriate assessment of the local water table level in the foundation design.
