Estudio geotécnico in Casas de Juan Núñez

In Casas de Juan Núñez, soils of limestones, dolomites and marbles predominate, which form the greater part of the geological substrate. This type of material generally exhibits good bearing capacity, favouring the selection of shallow foundations in most cases. The gravel and compact sands, present in smaller proportions, provide adequate performance for founding, provided that density and gradation are controlled. Fine sands and silts are uncommon and, given their characteristics, are considered less favourable for supporting foundations.

Seismicity in the area is very low, with only seven events recorded over thirty years, with a maximum magnitude considerably lower, meaning that this factor does not condition the structural design of the buildings. However, given the predominance of limestones and dolomites, it is crucial to verify the presence of karstic phenomena before undertaking any foundation work, as underground voids may affect stability. In addition, the non-clayey substrate rules out the risk of expansivity. Thus, the main geotechnical constraint is the possible existence of karstic cavities, which requires specific prior investigation before design.
