Estudio geotécnico in Bunyola

In Bunyola, soils of fine sands and silts predominate, which form the main base of the ground, providing an intermediate bearing capacity and a variable response depending on the degree of compaction. The significant presence of gypsum, anhydrite and salts introduces the risk of dissolution of materials, a factor to be considered especially when selecting the foundation depth and type of foundation. Limestones, dolomites and marbles appear occasionally and may exhibit good bearing capacity but require specific studies to characterise their behaviour.

The seismicity in Bunyola is very low, with only one recorded event every 30 years and a low maximum magnitude (Mmax 2.5), so it does not represent a relevant constraint for structural design. However, the presence of materials susceptible to karst development, together with the risk of dissolution associated with gypsum and salts, requires a prior verification of the subsoil before any foundation. As it is a non-clayey substrate, the risk of expansivity is ruled out, with the main constraint being the potential instability arising from karst processes and chemical dissolution.
