Estudio geotécnico in Jarandilla de la Vera

In Jarandilla de la Vera, the prevailing geological substrate is composed mostly of granite, gneiss and other igneous rocks, which accounts for around 69% of the municipal surface area. These lithologies are characterised by very low deformability and high bearing capacity, making them suitable for supporting loads from medium and heavy buildings by means of shallow (direct) foundations. In addition, smaller areas occur with sandstones and conglomerates, whose mechanical strength is also usually good, although they may require complementary studies to assess the point presence of looser or heterogeneous materials. The low permeability of the predominant materials implies little susceptibility to settlement due to the washout or transport of fines, but it is recommended to verify the groundwater level in the vicinity of water bodies.

The seismic activity in the municipality is rated as notable, with 56 events in the last 30 years, although the maximum magnitude recorded (Mmax 3.1) is considered low and does not entail special requirements for the seismic design of structures. There are no signs of karstification or risks associated with swelling, since the non-clayey substrate rules out this type of pathology. Thus, the most important geotechnical conditions to consider are the presence of rock masses as a foundation horizon and the possible local variability of secondary detrital materials.
