Estudio geotécnico in Redondela

In Redondela, sandstones, conglomerates and flysch predominate; materials that account for more than half of the ground and are characterised by their compactness and generally good bearing capacity. Slates and schists are also common, adding some heterogeneity to the substrate, although they do not usually seriously compromise foundations. Given the low overall permeability of these soils, the risk of collapses due to washout is low, but there may be localised shallow aquifers, which must be identified during investigations to ensure a stable foundation adapted to the ground conditions.

Local seismicity is very low, with only two events of maximum magnitude 2.2 every 30 years, so the impact of seismic loads is practically negligible in structural design. The non-clayey substrate rules out risks associated with expansive soils, allowing conventional foundations to be designed using bearing capacity and ground heterogeneity criteria, with the possible presence of water-bearing levels being the main aspect to control during the geotechnical study in Redondela.
