Geotechnical study in Mollina

In Mollina, the ground is characterised primarily by the presence of fine sands and silts, as well as sandstones, conglomerates and flysch. These materials, dominant in the area, usually show a medium bearing capacity, which allows direct foundation solutions in most cases, although the frequent fine-grained nature of some of these soils may require specific verification of the bearing level. Occasional layers of limestone, dolomite and marble may increase the strength of the stratum at greater depths, while the generally low permeability could affect the management of groundwater during the construction phase.

Seismicity in Mollina is very low, with only 6 events recorded over 30 years and a maximum magnitude of 2.8, which implies a low risk of relevant seismic activity for structural design. However, the potential existence of karstic formations requires checking the integrity of the subsoil before carrying out the foundation, since the presence of cavities or subsurface dissolution may compromise stability. The non-clayey subsoil rules out expansivity problems, establishing the possible presence of karst as the main geotechnical constraint to be examined in the area.
