Estudio geotécnico in Lourenzá

In Lourenzá, the subsoil is formed mostly by slates and schists, metamorphic materials with high compactness and very low permeability. This type of soil provides good bearing capacity, allowing shallow direct foundations when no significant alterations are detected in the rock. However, the presence of locally superficial levels that could store water via structural discontinuities must be assessed to prevent possible drainage problems in the foundation.

Seismic incidence in Lourenzá is classified as moderate, with 10 recorded events in the last 30 years and a maximum magnitude of M3.4, indicating that seismic action does not constitute a critical constraint in structural design. Given the karst nature present in the region, it is essential to thoroughly verify the existence of any possible cavities before proceeding with the foundation construction, as they could compromise stability. The non-clayey substrate rules out the risk of expansivity as a relevant factor, leaving attention focused mainly on the geotechnical study of the karst.
