Estudio geotécnico in Barberà del Vallès

In Barberà del Vallès, the predominant ground is made up of fine sands and silts, with an occasional presence of gravels, compacted sands and materials such as sandstones, conglomerates and flysch. In general, these types of subsoil provide a good bearing capacity, particularly in areas where the coarse and compact fractions predominate. The wide extent and permeability of the aquifers also favour drainage, which makes it easier to choose conventional shallow foundation solutions, always adapting to the variability in the soil’s particle-size distribution detected in the geotechnical study.

Seismic activity in Barberà del Vallès is very low, with only 5 recorded events over 30 years and very small maximum values (Mmax) of magnitude, which minimises the influence of seismicity on structural design. The fact that the subsoil is non-clayey rules out risks associated with ground expansivity. Overall, the main geotechnical aspect to be controlled will be particle-size heterogeneity and the presence of aquifers—points to be assessed before defining the optimum foundation solution.
