Estudio geotécnico in Celanova

In Celanova, soils composed of sandstones, conglomerates and flysch predominate, accounting for almost 60% of the substrate, accompanied by shales and schists in a significant proportion. These lithologies are characterised by their firmness and low deformability, which generally provides good bearing capacity for the construction of shallow foundations, especially in compact sandstones and conglomerates. However, the occasional presence of water masses requires attention in specific drainage and stability studies before work begins, as certain areas may host shallow aquifers or accumulate moisture if there is discontinuity in the materials.

Seismicity in Celanova is at a moderate level, with 31 events recorded over 30 years and a maximum magnitude of 3.1; these values do not severely condition structural design, although it is advisable to take them into account in singular projects. There is no evidence of karstification or of relevant expansiveness, since the substrate is not clayey, which considerably reduces this type of geotechnical risk. In conclusion, the main constraint for geotechnical studies in Celanova stems from the variable permeability and the possible flow of groundwater, making it essential to correctly characterise the depth and extent of the bearing materials in each plot.
