Estudio geotécnico in Terradillos

In Terradillos, sandstones, conglomerates and flysch predominate as the geotechnical substrate, representing more than 79% of the soils present. These materials, of lithified nature and high compressibility, generally provide an adequate bearing capacity for shallow foundations, although the less competent flysch facies and the possible presence of interbedded layers of sand and silt should be assessed locally, as they may influence the distribution of stresses. The limited presence of limestones, dolomites and marbles, together with some gravels and sands, reinforces the predominance of highly consistent materials; however, in situ testing is recommended to confirm the geomechanical uniformity at the specific site.

Seismicity in Terradillos is very low, with only one event detected in the last 30 years and a recorded maximum magnitude of 1.8, which implies a practically negligible seismic constraint in structural design. There are no signs of karst processes or risks linked to expansivity, since the geotechnical substrate is not clayey. Therefore, the main consideration in geotechnical studies focuses on the accurate characterisation of the stiffness and continuity of the dominant materials in order to define the optimal foundation depth.
