Estudio geotécnico in Rodeiro

In Rodeiro, formations of sandstone, conglomerates and flysch predominate, constituting more than 68% of the subsoil, followed by shales and schists. These soils are commonly compact and provide a good bearing capacity for shallow foundations, although the abundance of laminated materials and the possible presence of mudstones in the flysch may require analysis to avoid differential settlements. Mostly low permeability implies that any drawdown in the groundwater table, if present, will be slow, and the drainage conditions during the construction phase should be assessed.

With regard to geotechnical risks, seismicity in Rodeiro is moderate, with 13 events over 30 years and a low maximum magnitude (Mmax 2.2), so no specific reinforcement is required for seismic activity in the structural design. The non-clayey subsoil eliminates the risk of expansivity, providing additional stability. There are no risks associated with karst. Therefore, the most relevant condition to control will be the proper identification of the laminated lithology and its degree of compaction before founding, particularly in areas with a high flysch content.
