Estudio geotécnico in Vilafant

In Vilafant, sandstones, conglomerates and flysch predominate as the substrate, representing approximately half of the municipality’s ground. The also significant presence of fine sands, silts and, to a lesser extent, limestones and dolomites indicates lithological heterogeneity. These materials, generally of low permeability, give the subsoil a medium to good bearing capacity, although the possible presence of deep aquifers may require studies of hydraulic stability. For foundations, it is essential to correctly identify the local nature of the ground, particularly to avoid differential settlements at contacts between different strata.

Seismic activity in Vilafant is very low, with only 2 events over thirty years and an Mmax of 1.6, which represents a low seismic risk for structural design. However, since there are carbonate formations (limestones and dolomites), the presence of karstification must be verified before proceeding with any foundation work, as this factor can significantly affect long-term stability. The absence of clayey substrates rules out expansivity-related risks, with the main constraint being prior investigation into possible karst cavities.
