Estudio geotécnico in María de Huerva

In María de Huerva, the dominant materials are gypsum, anhydrite and salts, together with frequent outcrops of limestones and dolomites. This composition significantly influences bearing capacity parameters, since both gypsum and salts pose a risk of dissolution and potential differential settlement, especially in the presence of extensive, highly permeable aquifers. In turn, the presence of fine sands and silts, although occasional, calls for additional caution due to their lower consistency, whereas foundations on compact gravels and sands are uncommon.

As for secondary geotechnical aspects, the area shows moderate seismicity, with 35 events over 30 years, although the maximum magnitude observed is low (Mmax 2.5), which notably reduces the seismic influence in structural design. It is essential to consider the possible presence of karstification in the levels of limestone and gypsum before executing any foundation work, since this phenomenon can cause cavities and unanticipated subsidence. The substrate presents no risk of expansivity because it is not clayey; accordingly, the main technical constraint is rigorous verification of karst processes and dissolution in gypsum-bearing materials.
