Estudio geotécnico in Santa Cruz de la Zarza

In Santa Cruz de la Zarza, the predominant geological substratum consists of limestones, dolomites and marbles, frequently accompanied by sandstones, conglomerates and materials of the flysch type. These rock-like soils generally offer good bearing capacities, facilitating the execution of shallow foundations directly on them provided they are found at an adequate depth. However, the presence of gypsum, anhydrite and salts is also detected, which requires particular attention due to the risk of dissolution of these materials, which may affect the stability and durability of the foundations in the long term. Extensive and highly permeable aquifers can increase vulnerability to this phenomenon, making it essential to verify it in any geotechnical study prior to construction.

Seismic activity in Santa Cruz de la Zarza is very low, with fewer than 10 significant events over thirty years and a maximum magnitude below 4.0, so seismicity does not represent a relevant technical constraint in the usual structural design. The non-clayey nature of the substratum also rules out risks of ground expansivity. Nevertheless, the existence of carbonate materials makes it necessary to rule out active karst processes through a specific study, since their presence could decisively condition the choice and foundation system to be adopted, becoming the main factor to control in local geotechnical feasibility.
