Estudio geotécnico in Serón

In Serón, the predominant subsoil is composed of phyllites and schists, which make up more than 80% of the ground. This type of soil is characterised by low permeability and competent behaviour, which benefits bearing capacity and allows shallow direct foundations to be considered in many cases. The occasional presence of compact gravels and sands may provide localised alternatives for foundation design, whereas fine sands and silts, due to their low frequency, rarely condition the design. It is important to note that the general permeability of the area may lead to isolated shallow aquifers.

With regard to seismic risk, Serón shows moderate seismicity, with 32 events over 30 years and a maximum magnitude of 4.5; therefore, this variable must be taken into account in structural calculations. The existence of karstification in the area implies the need to adequately verify the ground before any foundation, to rule out the presence of voids or cavities. The non-clayey substratum removes concern about expansive soils, so the main geotechnical constraint lies in the likelihood of karst and seismic action.
