Estudio geotécnico in Felanitx

In Felanitx, white or soft expansive clays predominate, together with a significant percentage of limestones, dolomites and marbles, as well as fine sands and silts. This alternation of materials implies variability in bearing capacity, making it necessary to analyse the thicknesses and continuity of the clay layers in order to define the most suitable foundation solutions. The presence of gypsum, anhydrite and other salts, although infrequent, introduces an additional risk factor due to dissolution, particularly in areas where these lithologies crop out or are located close to the bearing level.

Seismicity in the municipality is moderate, with 24 events recorded over the last 30 years and a maximum magnitude lower than the critical structural values, so it constitutes a secondary constraint in the design. It is important to note the possible existence of karst-related phenomena associated with the carbonate formations, which makes it necessary to verify the presence of cavities or dissolutions before defining any type of foundation. In conclusion, the main conditioning factor of the geotechnical study in Felanitx is lithological diversity and the potential impact of karst processes.
