Estudio geotécnico in Igorre

In Igorre, the ground is characterised mainly by the presence of sandstones, conglomerates and flysch, rock formations of considerable strength and low deformability that ensure good bearing capacity conditions for shallow foundations. Limestones, dolomites and marbles also occupy a significant portion of the subsurface, providing stiffness and stability, although locally they may present certain discontinuities. The occasional presence of fine sands and silts requires a targeted analysis, but broadly speaking the dominant bedrock favours conventional foundation design, and the impermeability of these materials limits the susceptibility to moisture-related problems on site.

From a seismic point of view, the area shows notable activity with 94 events over 30 years, although the maximum magnitude reported (Mmax 3.7) is moderate and does not impose extraordinary requirements for structural design beyond the usual regulations. No active karst processes are observed, nor is there significant presence of expansive clays, since the non-clayey substratum rules out risks associated with expansivity. In summary, the main factor to consider for the geotechnical study in Igorre is to ensure the local homogeneity and compactness of the ground, together with specific verification in areas where more loose materials outcrop.
