Estudio geotécnico in Cuéllar

In the municipality of Cuéllar, soils of compacted gravel and sand predominate, together with frequent outcrops of limestones, dolomites and marbles, which provides good bearing capacity and favours shallow foundations for buildings with moderate or high loading. However, the occasional presence of gypsum, anhydrite and salts introduces a risk of dissolution that must be analysed thoroughly to avoid foundation-related pathologies. The formations show low surface permeability, although relevant deep aquifers may develop from a hydrogeological point of view.

Seismicity in Cuéllar should be considered a priority factor in structural design, as it has a high number of recorded events (more than 150 in 30 years) and an estimated maximum magnitude of 4,7. Likewise, given the calcareous-dolomitic substrate, the possible presence of karstification requires specific checks before undertaking any foundation. The non-clayey substrate rules out the risk of expansivity, so the main geotechnical constraint lies in the interaction between seismicity, karst and the dissolution processes associated with gypsum and salts.
