Estudio geotécnico in Barbate

In Barbate, the dominant substrate is made up of limestones, dolomites and marbles, accompanied by sandstones, conglomerates and flysch, which indicates the presence of hard and competent materials. This type of substrate favours high bearing capacities for foundations, making it suitable for shallow or direct foundations in most cases. The local occurrence of compact gravels and sands can provide equally valid alternatives, provided that the consistency and homogeneity are assessed, whereas fine sands and silts, due to their low bearing capacity, must be analysed before they are accepted as a support level.

Seismicity in this municipality is very low, with only 4 events in the last 30 years and a maximum magnitude of 3, so seismic risk is not considered relevant for construction. The non-clayey nature of the substrate rules out the risk of expansivity in the soils of the area. Given this geotechnical context, the main technical consideration focuses on the point-specific characterisation of the materials on site and verifying that there are no sandy or silty layers beneath the proposed foundations.
