Estudio geotécnico in Ribamontán al Mar

In Ribamontán al Mar, hard materials predominate, such as sandstones, conglomerates and flysch, accounting for more than half of the substrate, while calcareous formations — such as limestones, dolomites and marbles — are also significant. These soils generally exhibit high bearing capacity, allowing conventional direct foundations; however, it will be fundamental to prevent any impact on layers of fine sands and silts, which appear occasionally and may present low compaction and drainage problems. The impermeability of most formations facilitates hydrogeological control on site, although in places superficial aquifers may be found that require specific measures for their management and for the design of foundations.

Seismicity is very low, with only 3 events over 30 years and a maximum magnitude of 2.7, so seismic risk does not constitute a relevant constraint for structural design. However, the notable presence of calcareous materials makes it essential to verify the possible existence of karst cavities before carrying out any foundation work, since karst development is a specific risk factor in the area. The absence of clayey substrates eliminates the risk of expansivity. The main geotechnical constraint in this municipality, therefore, is the potential presence of karst in carbonate materials, which must be investigated in any geotechnical study prior to construction.
