Estudio geotécnico in Alegia

In Alegia, soils formed by limestones, dolomites and marbles predominate, representing more than 86% of the substrate. These rock materials are generally compact and provide good bearing capacities, which facilitates the execution of direct foundations of a shallow or deep type depending on the local stratigraphy. Occasional layers of fine sands and silts may show lower stability; therefore, their location during site works is fundamental to avoid founding on less competent strata.

Seismic activity in Alegia is very low, with a single recorded event in the last 30 years and a maximum magnitude of 2.8, so seismicity does not represent a severe constraint for structural design. The non-clayey substrate eliminates the risk of expansiveness. However, due to the karstified nature of the carbonate formations, it is essential to verify the presence of cavities or dissolution before undertaking any type of foundation, thereby making the karst phenomenon the main local geotechnical constraint.
