Geotechnical study in Bujalance

In Bujalance, the substrates of limestones, dolomites and marbles predominate, which generally ensures a high bearing capacity for foundations. The presence of fine sands and silts is occasional and, although they may locally affect the ground’s homogeneity, in most cases the rock formations allow direct and stable foundation systems. The inherent impermeability of these materials limits water migration, although surface aquifers may exist due to local accumulation.

The seismicity of the area is very low, with only 4 recorded events over 30 years and a low maximum magnitude, which removes the need to reinforce structures on account of seismic effects. Although expansive clays exist in a subordinate manner, their location in environments without a moisture deficit mitigates the risks of expansivity. Thus, the main factor to consider in the geotechnical studies of Bujalance is the point-specific characterisation of any possible levels of sands and silts in order to optimise the appropriate foundation solution.
