Estudio geotécnico in Cabra

In Cabra, the dominant substrate is composed of limestones, dolomites and marbles, materials that account for approximately 68% of the local soils. These lithologies provide a high bearing capacity and allow direct foundations to be considered in most cases. Nevertheless, the frequent presence of carbonate formations implies the possibility of encountering karstic structures, so it is essential to carry out a detailed check of the continuity and competence of the ground before defining the type of foundation. The fine sands, silts and other lithologies present in smaller proportions may cause localised variations in compactness and settlements, but they do not usually significantly condition the overall geotechnical design.

Seismic activity in Cabra is classified as moderate, with 21 recorded events over the last 30 years and a low maximum magnitude (Mmax 2.4), which reduces the need to adopt specific structural measures against seismic risk. The analysis of expansivity rules out hazards associated with clayey soils, as the substrate is not clayey. The main geotechnical constraint in Cabra is given by the possible presence of karstifications; these must be identified and assessed in detail, as they may affect both the stability and the feasibility of the foundation.
