Estudio geotécnico in Olocau

In Olocau, calcareous soils predominate, accompanied by frequent outcrops of sandstones, conglomerates and flysch, with soils of limestones, dolomites and marbles. These materials generally provide good bearing capacity, enabling efficient shallow and deep direct foundations. The presence, although rare, of gypsum, anhydrite and salts introduces a certain risk of dissolution, which must be assessed particularly in areas where these materials crop out. The scarce occurrence of hard clays minimises the risk of differential settlements, and the nature of the subsoil generally allows for a good structural response. Local aquifers and those with moderate production may influence the planning of trenches and drainage.

Seismic activity in Olocau is moderate, with 27 events in the last 30 years and a maximum recorded magnitude of 3.4, so seismic risk, although not a priority, must be taken into account in relation to the current regulations. The non-clayey subsoil rules out the problem of expansive soils. Given the predominance of carbonate rocks, verifying karst features is an essential aspect prior to foundation works, since the presence of cavities can significantly affect ground stability. In this municipality, the possible presence of karst and the local existence of gypsum are the main geotechnical factors to be investigated in depth before any construction development.
