Estudio geotécnico in Valenzuela

In Valenzuela, soils formed by limestones, dolomites and marbles predominate, together with a significant presence of sandstones, conglomerates and flysch, while fine sands and silts are observed only occasionally. These lithologies, which are generally little deformable and have low permeability, usually provide an adequate bearing capacity for shallow foundations. However, in areas where deposits of sands and silts crop out, ground stability may be compromised; therefore, a detailed analysis of the support level is recommended before defining the foundation type.

As regards seismicity, Valenzuela shows notable activity, with 54 events over the last 30 years and a maximum recorded magnitude of 4.6, which requires that seismic risk be considered in the structural design of any building. It is also worth highlighting the presence of zones with predominantly expansive clays, which considerably increases the danger of differential movements and problems associated with ground heave. Therefore, the main constraint for projects in this municipality is the geotechnical risk arising from expansive clays, which must be evaluated in detail through a specific geotechnical study.
