Estudio geotécnico in Paracuellos de Jarama

In Paracuellos de Jarama, water-bearing masses and detrital materials predominate, such as sandstones, conglomerates and flysch, with the occasional presence of slates and schists also observed. The existence of compacted gravels and sands, although in the minority, can provide favourable conditions for shallow foundations, provided these layers are located at the appropriate depth. However, the high proportion of soils with moderate permeability, associated with the presence of extensive or discontinuous aquifers, requires a detailed analysis of the groundwater table and may condition the type of foundation recommended depending on local stability and bearing capacity.

Seismic activity in Paracuellos de Jarama is very low, with only 5 events in the last 30 years and a low maximum magnitude, so seismic risk is of little significance for structural design. Although the clays present are not expansive or appear embedded in non-clayey matrices, there is some risk of expansivity, so it is essential to identify this among the potential foundation materials. The main technical constraint in the municipality stems from the management of groundwater and the appropriate characterisation of bearing capacity in areas of detrital soils and the presence of water.
