Geotechnical study in Granja de Torrehermosa

In Granja de Torrehermosa, the presence of compacted gravels and sands predominates, together with slates and schists, forming a solid subsoil with low deformability. The bearing capacity of these materials is favourable for shallow foundations, and the use of piles is usually unnecessary unless there is a specific occurrence of fine sands and silts, which in isolated volumes may require additional checks. The predominantly impermeable nature of the ground reduces the risk of ground movement due to changes in moisture content and avoids the usual problems associated with soft soils.

Seismicity in the municipality is very low, with only 4 recorded events over 30 years and a maximum magnitude of 2.5, so it does not constitute a significant constraint in the design of structures. There are no signs of karstification, nor has the presence of expansive clays been reported, which translates into an absence of risks associated with undesirable volumetric movements. This highlights the stable behaviour of the ground, making lithological homogeneity and low permeability the key factors to be considered in the local geotechnical study.
