Estudio geotécnico in Mancor de la Vall

In Mancor de la Vall, fine sands and silts predominate, accounting for more than 70% of the surface materials, occasionally accompanied by gypsum, anhydrite, salts and some fractions of limestones and dolomites. The presence of predominantly granular soils, together with layers of soluble nature such as gypsum and salts, requires a detailed analysis of bearing capacity and behaviour under loads, since the dissolution of these materials can compromise the stability of foundations. In addition, generally low permeability can limit the drainage of water, increasing vulnerability to certain geotechnical processes.

The seismic activity in the area is moderate, with 24 events over thirty years and a maximum magnitude of 3.2, which does not constitute a critical constraint for structural design. However, the presence of karstic development associated with the calcareous substratum makes it necessary to carry out a prior, thorough verification before undertaking any foundation. Since the substratum is not clayey, the risk of expansivity is ruled out. As the main constraint, the need to assess both the possibility of dissolution processes in gypsum and salts and the existence of karstic risk in the subsoil stands out.
