Estudio geotécnico in Gilena

In Gilena, the subsurface is dominated mainly by sandstones, conglomerates and flysch, accompanied by certain areas with limestones, dolomites and marbles, as well as the occasional presence of fine sands and silts. These materials, in general, provide a good bearing capacity and stability for the foundations of buildings, although the impermeability of the overall formation may favour the appearance of local shallow aquifers. No muds or peats are detected, so site conditions allow conventional foundation solutions to be selected, avoiding the need for special treatments except in the areas of silts.

Seismic activity in the municipality is very low, with only 3 recorded events over 30 years and a maximum magnitude of 3.9, so the seismic effect does not represent a relevant constraint for structural design. The non-clayey substrate eliminates the risk of problematic expansivity, providing greater safety against swelling movements. However, the presence of carbonate materials such as limestones and dolomites implies that the existence of karst features must be verified in advance before undertaking any foundation works, this being the primary geotechnical condition to take into account in field studies.
