Estudio geotécnico in Begur

In Begur, geotechnical studies reveal the predominance of fine sands and silts alongside formations of limestones, dolomites and marbles, suggesting a combination of granular and compact materials with notable bearing capacity. The secondary presence of slates, schists, granite and gneiss may provide varied options for selecting the optimal foundation level depending on the specific sector of the municipality. The identification of white, soft expansive clays, although occasional, requires localised attention, whereas the formations usually show low permeability, which limits liquefaction and erosion risks in most projects.

From a geodynamic standpoint, Begur lies in an area of very low seismicity, with a maximum magnitude reported of 2.4 over the last 30 years, which minimises the influence of this factor on structural design. The absence of a prevalent clay substrate rules out any significant risk of expansivity for most foundation projects. The main constraint in this municipality will therefore be lithological heterogeneity and the correct identification of the substrate type to ensure foundation stability.
