Estudio geotécnico in Écija

In Écija, fine sands and silts predominate, followed by carbonate formations such as limestones, dolomites and marbles. These materials usually confer medium to good bearing capacity, and are suitable for shallow foundations where adequate compaction and continuity exist. The occasional presence of sandstones and conglomerates further strengthens the load-bearing profile, while compacted gravels and sands, although infrequent, can provide localised points of high competence. Permeability is generally low or very low, which will minimise risks associated with piping and liquefaction; however, the existence of shallow aquifers must be taken into account, particularly when planning drainage.

Seismic activity in Écija is very low, with only three recorded events over thirty years and a maximum magnitude below 4, which minimises the need for special structural requirements for this aspect. However, the presence of limestone and dolomitic formations makes it essential to rule out the existence of karstification before carrying out any foundation, as it could affect the safety and stability of the structures. In addition, as the subsoil is non-clayey, any serious risk associated with expansive soils is ruled out, so the main factor to control will be the potential presence of karst cavities.
