Estudio geotécnico in Elda

In Elda, the predominant substrate is composed of sandstones, conglomerates and flysch, occupying almost 68% of the municipality, which ensures soils with good strength and moderate bearing capacity for buildings. The occasional presence of gypsum, anhydrite and salts requires special attention due to the potential risk of dissolution, whereas compact gravel and sand layers, although rare, can provide optimal ground conditions for shallow foundations. In general, the low permeability of the formations makes it necessary to check for the presence of deep aquifers before determining the most suitable foundation system.

Seismic activity in Elda is very low, with a single minor event (Mmax 2.1) in the last thirty years, so seismicity does not represent a relevant structural constraint. However, due to the possibility of karst development in areas with limestone, dolomites or gypsum-bearing rocks, it is essential to carry out a detailed verification of the karst phenomenon before constructing any foundation, as it could affect ground stability. Since the substrate is not clayey, the risk of expansiveness is ruled out as the main problem in this municipality.
