Estudio geotécnico in Valverde de Leganés

In Valverde de Leganés, soils formed by sandstones, conglomerates and flysch predominate, representing more than 70% of the near-surface strata. These lithologies are characterised by adequate strength and low deformability, which provides good conditions for the bearing capacity of shallow foundations. Occasionally, overconsolidated clay and marl levels appear, as well as interbeds of slate and schist, but their presence is limited and generally does not determine the choice of foundation type, unless they are located in the specific bearing level.

The recorded seismic activity is very low, with only 5 events in the last 30 years and a maximum magnitude of 4.4, so this risk is low for structural design. On the other hand, the possible existence of karstic phenomena must be carefully verified before any foundation is carried out, although the risk of expansivity is ruled out since the substratum is not clayey. The main technical factor to take into account in this municipality is checking for cavities or solution features associated with karstic processes, which may affect the stability of the foundation.
