Geotechnical study in Xeraco

In Xeraco, soils of compacted gravels and sands predominate, followed by formations of limestones, dolomites and marbles, which translates into excellent bearing capacity and favourable conditions for shallow foundations. The extensive presence of highly permeable aquifers supports ground stability, although it is recommended to check the depth of the water table during the geotechnical study. Clays and hard marls are infrequent, which reduces the difficulties associated with plastic or compressible soils.

Seismic activity in Xeraco is very low, with only 3 recorded events in the last 30 years and a maximum magnitude of 2.3, meaning that seismic risk is not relevant in design for construction. However, the presence of carbonate materials implies potential karst development, so it is necessary to confirm the absence of cavities or dissolution processes before defining the final foundation. The non-clayey substrate rules out expansiveness risk; therefore, the main technical constraint in the area is the thorough verification of karst in areas with limestones and dolomites.
