Estudio geotécnico in Aldeanueva de Ebro

In Aldeanueva de Ebro, the dominant subsoil is made up of compact gravels and sands, followed by sandstones, conglomerates and flysch formations. These materials provide excellent bearing-capacity conditions and usually allow shallow direct foundations, as the compactness and granular character significantly reduce the risk of differential settlement. It is important to note the local presence of fine sands and silts, together with areas of groundwater mass, which requires specific controls to prevent impacts from saturation or possible washout, particularly in the design of the foundation support. Owing to its high permeability and aquifer character, it is recommended to pay careful attention to hydrogeological control during the construction phase.

The seismic profile of the municipality shows significant activity, with 200 events over 30 years, although the maximum recorded magnitude (Mmax 4) does not exceed structurally critical levels. The non-clayey subsoil virtually rules out any threat from soil expansivity. No karst phenomena are reported in the area, so the dissolutions and subsidence associated with this process do not constitute a constraint. In conclusion, the main parameter to consider in the geotechnical study will be the correct identification of the lateral variability of granular materials and the management of the groundwater table; these are key aspects for optimising the foundation design.
