Estudio geotécnico in Bonares

In Bonares, limestones, dolomites and marbles predominate as subsoil materials, accounting for more than 80% of the area, creating a typical scenario of soils with high compactness and good bearing capacity for foundation design projects. Their presence generally ensures favourable conditions for transmitting loads to the ground, although possible minor lithological variations should be assessed, such as the occasional presence of sandstones, conglomerates and flysch, which may show differences in the soil–structure interaction. Water bodies, although scarce, may indicate the presence of shallow aquifers or areas locally saturated, which would require a specific assessment in the design of supports.

Seismic hazard in Bonares is very low, with only about 2 events over 30 years and a maximum recorded magnitude of 1.9, so it does not constitute a relevant factor in the sizing of structures. There are no indications of karstification that would condition the local geotechnical model, and the dominant formation lacks a significant clayey substrate, which limits the risk of expansivity despite the presence of non-expansive or dispersed clays in the matrix. In general, the main requirement in the geotechnical studies for this locality will be detailed lithological characterisation to confirm the suitability of the bearing layers and rule out zones that are locally problematic.
