Estudio geotécnico in Majadahonda

In Majadahonda, the dominant ground is made up of sandstones, conglomerates and flysch, accounting for more than 90% of the surface. These materials usually exhibit good bearing capacity and low deformability, which favours the selection of shallow foundations in most cases. Limestones, dolomites and marbles occur in isolated locations; these lithotypes also allow adequate foundation resistance, unless they present significant fracturing, which should be assessed on a case-by-case basis. In general, the presence of moderate aquifers also suggests taking into account the possible variability in the ground moisture at certain depths.

The seismicity recorded in Majadahonda is very low, with a low event index and a maximum magnitude (Mmax) of 1.7, so it does not constitute a relevant constraint for structural design. With regard to expansiveness, the analysis indicates a non-clayey matrix with the presence of non-expansive or dispersed clays; therefore, the risk of expansiveness is low and does not represent a significant limitation for the project. In conclusion, the selection and sizing of the foundation in Majadahonda will depend mainly on the specific lithological variability and interaction with aquifers, without any severe geotechnical constraints associated with soil seismicity or expansiveness.
