Estudio geotécnico in Agulo

In Agulo, geotechnical studies show a clear dominance of sedimentary formations, mainly sandstones, conglomerates and flysch, which represent almost 80% of the substratum. These well-cemented lithologies offer adequate thickness and stability for supporting buildings with direct or shallow foundation solutions in most cases, although it may be advisable to carry out mechanical reconnaissance campaigns to verify the ground’s uniformity. The secondary presence of granite, gneiss and other igneous rocks strengthens the ground’s bearing capacity in specific areas, allowing even semi-deep foundations or isolated spread footings depending on the topography and effective depth of the competent substratum.

As regards seismic risk, Agulo exhibits moderate seismicity with 11 events recorded in the last 30 years and a low maximum magnitude (Mmax) of 2.2. These factors indicate that it usually is not a primary conditioning factor in local structural design. The municipality has no karst development and no soils with problematic expansivity, so the main geotechnical constraints focus on correctly characterising the composition and stratigraphy of the sedimentary layers of the ground in order to select the most efficient foundation, without the need for special measures to address instability problems associated with clayey soils or dissolutions.
