Estudio geotécnico in Algaida

In Algaida, the dominant geological substrate is composed mainly of limestones, dolomites and marbles, which generally provides a good bearing capacity and allows the execution of shallow direct foundations in most cases. The presence of white or soft expansive clays, although common in certain areas, is secondary to the predominance of hard, compact materials. Isolated outcrops of gypsum, anhydrite and salts are also found, which may locally pose risks of dissolution and sinkholes if they are not properly identified during the geotechnical study. It is essential to avoid direct foundation on soluble materials in order to guarantee long-term stability.

Seismic activity in Algaida can be classified as moderate, with 24 events recorded over the last 30 years, and a maximum magnitude of 3.2, indicating that the seismic impact on structures is low, although not negligible. Given the characteristics of the substrate, karst development is frequent; therefore, it is essential to verify the presence of cavities or instances of dissolution before carrying out any foundation, as these can compromise the integrity of the structures. The absence of significant expansivity risks in the main substrate means that monitoring karst-related phenomena is the main determining factor of the geotechnical study in Algaida.
