Estudio geotécnico in Olleria

In l’Olleria, the dominant ground is formed mostly by limestones, dolomites and marbles, which account for approximately 98.7% of the substratum. These materials show high mechanical competence and usually provide a good bearing capacity for shallow foundations. In addition, due to their permeability and extent, the aquifers present in the area can influence the soil’s hydrological behaviour, so it is essential to consider the water table level and the possible effects of water in the design of the foundations.

Seismicity in l’Olleria is considered moderate, with 27 recorded events in the last 30 years and a maximum magnitude (Mmax) of 3.4, which does not represent severe seismic restrictions for normal building work. However, since the ground is made up of carbonate formations, it is a priority to check for the existence of karst phenomena, as the presence of cavities or dissolution can seriously compromise the stability of the foundations. The non-clayey substratum eliminates the risk of expansive effects, making karst the main geotechnical factor to be investigated before carrying out foundation works in the locality.
