Estudio geotécnico in Venturada

In Venturada, geotechnical studies usually find as the dominant substrate shales and schists, followed by sandstones and conglomerates, with occasional occurrences of limestones and igneous rocks. The predominance of metamorphic and sedimentary materials implies generally adequate bearing capacity, although the low permeability of these soils may condition the drainage of water and the behaviour under loads during wet seasons. The existence of gypsum, anhydrite and salts poses a risk of dissolution, so it is essential to carry out a detailed characterisation to define safe foundation levels and rule out the possibility of differential settlement, particularly in areas where these soft or soluble materials coincide.

As regards stability, seismicity in Venturada is very low, with a single relevant event and a low maximum magnitude, which minimises the seismic impact on structural design. However, the possible presence of karst in the substrate makes it necessary to verify the existence of caverns and voids before proceeding with the foundations, as they can seriously affect ground stability. The non-clayey substrate rules out significant risks of expansivity. The main geotechnical constraint in the area is the verification and characterisation of karstic phenomena and the possible presence of soluble gypsum-bearing materials in the soils.
