Estudio geotécnico in Salas

In the municipality of Salas, shales and schists predominate, representing more than half of the substrate materials, which provides an essentially rocky base with low permeability. Limestones, dolomites and marbles appear in a punctual way, locally adding lithological variability. In general, these soil types confer good bearing capacity for supporting buildings, although the arrangement and the state of fracturing of the metamorphic rocks can influence foundation design, particularly in areas where superficial aquifers associated with the low permeability of the materials may exist.

Seismicity in Salas is classified as very low, with only one recorded event over a period of 30 years and a maximum magnitude that does not represent any significant structural risk. However, given the presence of carbonate materials such as limestones, it is essential to verify the existence of karst processes before carrying out any foundation work, as the possibility of underground cavities could affect stability. The non-clayey substrate eliminates the risk of expansivity, so the main focus should be on checking for karst as an essential geotechnical conditioning factor.
