Estudio geotécnico in El Provencio

In El Provencio there is an absolute predominance of formations composed of gypsum, anhydrite and salts, materials recognised for their low permeability and susceptibility to dissolution processes. The bearing capacity in this environment may be compromised if the substrate is not correctly characterised, given the possibility of the appearance of underground voids and phenomena associated with the solubility of these minerals. This affects both the choice of foundation type and the control of any possible differential settlement.

Seismic activity in the area is moderate, with 40 events over 30 years and a maximum magnitude of 4.1, which recommends considering this factor in structural design. It is essential to verify the existence of karst processes before founding, due to the presence of gypsum and salts. The fact that the substrate is non-clayey rules out the risk of expansivity. The main constraint lies in checking for instability due to dissolution and the presence of karst, both of which are critical aspects for any construction intervention.
