Estudio geotécnico in Vilajuïga

In Vilajuïga, the predominant subsoil is composed mainly of granite, gneiss and other igneous rocks, accompanied in smaller proportions by overconsolidated clays and marls with a hard behaviour, as well as slates and schists that appear occasionally. These lithologies generally provide a high bearing capacity and low compressibility, which favours the use of shallow foundations in most situations. The low permeability of these formations limits the flow of groundwater, although small aquifers may exist at near-surface levels with local fracturing.

Seismic activity in the municipality is very low, with a small number of recorded events and a maximum magnitude below 4, which minimises the impact of seismicity on structural design. In addition, since the subsoil is not clayey, the risk of expansiveness due to swelling of clays is ruled out. The main geotechnical constraint in Vilajuïga is therefore the assessment of the quality and continuity of the rock mass at the specific project site.
