Estudio geotécnico in Daroca

In Daroca, sandstones, conglomerates and flysch materials predominate, providing soils with mechanical characteristics suitable for shallow foundations, provided that local uniformity and compaction are verified. The occasional presence of limestones, dolomites and marbles increases the strength of the subgrade, although it can also introduce variability in the geotechnical response. In addition, there are areas with gypsum, anhydrite and salts, which increase the risk of dissolution on contact with water, and this must be assessed in phases prior to the design of deep foundations. Slates and schists, although less common, may present weakness planes that condition local stability. In all cases, the generally low permeability limits the flow of water, but it is essential to identify any shallow aquifers that could alter the behaviour of the ground.

The seismicity of the area is significant, with 68 events over the last 30 years and a maximum value (Mmax) of 4.8, so the seismic parameters must be incorporated into the structural design of the project. Given the predominance of carbonate materials, the possible presence of karstification requires specific assessment before carrying out any foundation works, since hidden voids may jeopardise the safety of the works. The non-clayey subgrade rules out expansivity-related risks, allowing swelling problems to be ruled out, but the main geotechnical constraint will be checking for underground cavities and the potential dissolution of gypsum or salts.
