Estudio geotécnico in Calamocha

In Calamocha, sandstones, conglomerates and flysch predominate as sub-strata, together with a significant presence of limestones, dolomites and marbles—materials that ensure good bearing capacity and favourable conditions for shallow or deep direct foundations. Shales and schists appear occasionally and may require attention to their behaviour under load, while the presence of gypsum and salts indicates a localised risk of dissolution, which can compromise the stability of foundations if they are not studied properly. Permeability in the area is, in general terms, low, although surface aquifers associated with discontinuities may exist—an aspect that is relevant for water control during excavations.

Seismic activity in Calamocha is very low, with only 2 recorded events over 30 years and a very low maximum magnitude (Mmax 2.1), ruling out seismicity as a relevant conditioning factor for structural design. Although the ground does not show expansive clays, so the risk of expansivity is ruled out, the possibility of karsitic development associated with the carbonate formations requires careful verification before any excavation or foundation work, since the existence of voids can compromise the safety and stability of the works. The main factor conditioning geotechnical studies in this municipality is the assessment of karst potential and the checking of possible zones with gypsum or salts that may be susceptible to dissolution.
