Estudio geotécnico in Talamanca de Jarama

In Talamanca de Jarama, the predominant subsoil is made up of sandstones, conglomerates and flysch, which generally favours a good mechanical response for building foundations, provided that the competence of the bearing layer is verified. The occasional presence of slates and schists may locally introduce variations in bearing capacity. It is important to take into account the high proportion of mass of water at the surface, which could condition the optimum depth of support and require drainage measures or prevention against possible groundwater level rises in rainy phases. Limestones and dolomites are poorly representative in the area and do not usually determine the predominant behaviour of the soils.

Seismicity in Talamanca de Jarama is very low, with only 5 recorded events over 30 years and a maximum magnitude of 3, so the influence of seismic movements on the building is smaller and does not represent a relevant factor in foundation design. The non-clayey substrate rules out expansivity risks, favouring volumetric stability of the ground. The main constraint in building projects in the municipality lies in the possible presence of high groundwater levels and in the local variability of the bearing material; these are the key points to analyse through a specific geotechnical study.
