Estudio geotécnico in Rotglà i Corberà

In Rotglà i Corberà, the subsoil is dominated by compact gravels and sands, which provide high bearing capacity and favourable conditions for shallow foundations, provided that the groundwater table allows it. The frequent presence of gypsum, anhydrite and salts introduces specific risks related to dissolution processes, which may affect the ground’s stability and the long-term behaviour of structures, especially if there is water circulation. Limestone and dolomites are also identified, which suggests a possible influence of karst processes, and although hard clays are rare, they do not represent a relevant expansive constraint.

Local seismicity is very low, with only 3 events over the last 30 years and a low maximum magnitude of 1.8, so this factor does not pose a significant restriction for the design of infrastructure. It is essential to verify the presence of karstification phenomena before designing any foundation, due to the soluble nature of gypsum and the existence of limestone. In this way, the main constraint to be assessed in the geotechnical study will be the karst potential and the dissolution processes associated with the area’s evaporite materials.
