Estudio geotécnico in Las Rozas de Madrid

In Las Rozas de Madrid, the predominant soils correspond to sandstones, conglomerates and flysch, which denotes a resistant lithological composition and a good bearing capacity compared with looser or clayey deposits. This rocky nature favours solutions for direct foundations, although it is essential to adequately characterise the continuity of these materials given the presence of local aquifers and areas of moderate permeability, which may influence the ground behaviour under structural loads.

The municipality is located in an area of very low seismicity, with only 5 recorded events over 30 years and low magnitudes (Mmax 3), which minimises the relevance of the seismic constraint in the design of structures. Although expansive clays are not predominant, their scattered presence within a non-clayey matrix indicates the need to verify expansivity in specific plot studies, as local risk could occur. Thus, the main limiting factor is the control of dispersed clayey soils which, although not widespread, could affect the choice of foundation in certain locations.
