Estudio geotécnico in Villahermosa

In Villahermosa, the dominant subsoil corresponds to gypsum, anhydrite and salts, present in more than 70% of the soils, which significantly conditions the bearing capacity and the type of foundation that is viable. The presence of these materials implies a relevant risk of dissolution processes; therefore, it is essential to carry out a rigorous geotechnical study to determine ground stability. Limestones, dolomites and marbles, although less frequent, may appear as local hard points; whereas fine sands and silts and white/soft expansive clays are poorly representative and usually do not provide ideal support for shallow foundations.

The area shows moderate seismicity, with 25 events over the last 30 years and a maximum recorded magnitude of 4.2, a factor that should be incorporated into structural design for new projects. Given the possible presence of karstification, especially over gypsum and limestones, it is essential to verify the development of cavities or underground conduits before proceeding with the execution of foundations. As there is no dominant clayey subsoil, the risk of expansivity is practically ruled out. The main constraint for any work in the area is the geotechnical risk associated with the dissolution of gypsum and the existence of karst voids—issues that require particular attention during the design and execution phases.
