Estudio geotécnico in Alange

In Alange, compact gravels and sands predominate as substrates, standing out for their high bearing capacity and adequate drainage, which makes it easier to select conventional shallow foundations. Slates and schists are also present with some frequency, providing good stability, provided that their degree of weathering is assessed. Similarly, the presence of hard clays and marls in smaller proportions may offer a stable foundation, although it will be necessary to verify the regularity of these strata. Granitic formations or igneous rock, although less common, provide excellent support for deep foundations.

Seismicity in Alange is notable, with 52 events in the last 30 years and a maximum magnitude of 4.4, which requires specific attention in structural design to ensure the stability of the building against seismic movements. As there are no karst phenomena or appreciable risks of substrate expansivity, the main geotechnical limiting factor will be determined by the seismic response of the ground, as well as by the careful selection of the strata with the best bearing and draining characteristics in the presence of groundwater.
