Estudio geotécnico in Granja de Rocamora

In Granja de Rocamora, the subsoil is formed mainly by fine sands and silts, which affects both the bearing capacity and the choice of foundation type. The near-exclusive presence of this type of ground requires an accurate assessment of compaction and homogeneity, since both sands and silts can show local variability, affecting stability under loads. The low permeability detected indicates that problems with the accumulation of water at the surface and within the groundwater levels may occur, so it is advisable to investigate the presence of aquifers during any geotechnical study prior to construction.

Seismic activity in the area is very low, with only 5 recorded events over the last three decades and a maximum magnitude of 3.8, which notably limits the impact of this phenomenon on buildings. Nevertheless, the possible existence of karstification in the subsoil must be taken into account; it is essential to verify the presence or absence of cavities and dissolution processes before undertaking any foundation work, as these could seriously compromise stability. The absence of clayey soils eliminates the risk of expansivity, so the determining factor in geotechnical studies will be the control of karst conditions and the detailed characterisation of the deposits of sands and silts.
