Estudio geotécnico in Colmenar del Arroyo

In Colmenar del Arroyo, the predominant geotechnical substrate is mainly made up of granite, gneiss and other igneous rocks, followed in frequency by shales and schists. This type of ground is characterised by a high bearing capacity, which is generally favourable for shallow foundations. However, it is essential to take into account the occasional presence of sandstones and other detrital materials, although their limited extent usually does not significantly affect the design. The formations present have very low permeability, so they do not usually give rise to problems associated with rising groundwater levels.

The municipality shows a very low level of seismicity, with just one recorded event in the last three decades and a maximum magnitude (Mmax) of 1.7, which minimises the requirements for the seismic design of structures. There is no risk of karstification or signs of expansivity, since the substrate is not clayey. In short, the main technical consideration in Colmenar del Arroyo lies in the mechanical characteristics of the rock materials, which provide safe and predictable conditions for foundation design.
