Geotechnical study in Tórtola de Henares

In Tórtola de Henares, the predominant substrate is made up of limestones, dolomites and marbles, which account for approximately 61% of the surface geology. These materials offer a high bearing capacity and are suitable for robust direct foundations, provided that the prior existence of possible voids or discontinuities characteristic of their karst nature is verified. The presence of extensive aquifers, derived from the high permeability of these rock masses, can influence ground stability and may require hydraulic conditions to be incorporated in the foundation design.

Seismicity in the municipality is significant, with more than 200 events over 30 years and a maximum magnitude (Mmax) of 4.6, a factor that makes it necessary to integrate seismic criteria into structural design. The presence of karstic ground requires detailed studies to rule out the existence of cavities or subsidence before building foundations. Expansive clays are subordinate or located in climatic zones without an appreciable deficit, which reduces the associated risk, although it is still recommended to verify their local presence. The main limiting factor in the area is the combination of notable seismicity and karst risk, which must be carefully assessed in any geotechnical study.
