Geotechnical study in Chella

In the municipality of Chella, calcareous materials such as limestones, dolomites and marbles predominate; these make up most of the subsoil and habitually exhibit a high bearing capacity, suitable for most shallow foundations. It is important to note the occasional presence of gypsum, anhydrite and salts, which may pose risks of dissolution in certain areas, as well as smaller layers of fine sands and silts that could locally affect the uniformity of the supporting ground.

Seismic activity in Chella is very low, with a small number of events and moderate magnitudes, so seismicity does not constitute a primary constraint in structural design. Nevertheless, the presence of an environment with karst development implies the need to verify the existence of cavities at depth before founding, this being one of the most relevant factors for the feasibility and safety of construction projects. The absence of clayey strata rules out expansivity as a potential problem.
