Estudio geotécnico in Cove

In the municipality of Cala, the predominant materials are slates and schists, accompanied to a lesser extent by granite, gneiss and igneous rocks. This type of mineralogical substrate is usually characterised by high strength and favourable bearing capacity for most building projects, provided that the degree of weathering is not high. The low permeability of these soils also contributes to foundation stability, although it is advisable to analyse the possible presence of shallow aquifers in certain areas before defining the most suitable foundation type.

Seismicity in Cala is very low, with only two events over 30 years and a maximum recorded magnitude of 1,7, meaning that seismic risk is practically negligible in structural design. Since the substrate does not contain clays, there is no concern regarding expansivity. However, as it is an area with a possible presence of karstification, it is essential to carry out a detailed check on the existence of cavities or dissolution before executing any foundation, since this is the main constraint to be controlled in the local geotechnical study.
