Estudio geotécnico in Orusco de Tajuña

In Orusco de Tajuña, soils formed by sandstones, conglomerates and flysch predominate, accompanied in good proportion by limestones, dolomites and marbles. This lithic substrate generally provides adequate bearing capacity for shallow foundations, although the occasional presence of compact gravel and sand can offer viable alternatives depending on the depth of the competent stratum. The geological formations present tend to have low near-surface permeability, but they may host significant aquifers at depth, which must be taken into account when defining foundation levels and drainage systems.

With regard to seismic behaviour, the municipality shows moderate seismicity with 33 recorded events over 30 years, although of low maximum magnitude (Mmax 2.4), which reduces the impact of seismic requirements on structural design. However, given the predominance of carbonate materials such as limestones and dolomites, there is a possibility of karstification developing, so it is essential to check the stability and continuity of the ground before proceeding with the foundation. In conclusion, prior verification of karst phenomena is the main geotechnical constraint in the area.
