Estudio geotécnico in Corvera de Toranzo

In Corvera de Toranzo, the strata formed by sandstones, conglomerates and flysch predominate, together with a significant presence of limestones and dolomites. These lithologies provide good conditions for bearing capacity and are suitable for shallow foundations on rock. However, the limited presence of fine sands and silts, as well as the granite and igneous rocks, does not influence in a determining way the usual design of the supports. The low permeability of the ground requires attention to possible accumulations of water at ground surface level, particularly in large-scale projects.

Seismicity in the area is very low, with only 1 event in 30 years and a low maximum magnitude, which minimises this factor in structural design. It is nonetheless essential to verify the possible existence of karstification in the carbonated areas before defining the foundation, as it could compromise ground stability. The non-clayey substrate rules out the risk of expansivity, so the possible presence of karst cavities is established as the main factor requiring attention in any geotechnical study for developments in this municipality.
