Estudio geotécnico in Cornellà del Terri

In Cornellà del Terri, the dominant geological substrate is composed mainly of sandstones, conglomerates and flysch, which represent most of the underground environment. These formations usually show low permeability at the surface, although they may host aquifers at greater depth. The secondary presence of limestones, dolomites and marbles, together with layers of gravels, compacted sands, fine sands and silts, provides a favourable context for foundations, as bearing capacities are typically suitable for building and civil engineering projects, provided that the thicknesses and compaction states of these materials are duly considered.

With regard to geotechnical risks, the area does not present any significant features of expansivity, since the non-clayey substrate rules out this problem. Seismicity in the area is very low, with barely two recorded events over three decades and a maximum magnitude that is considerably low. In addition, the absence of karstification simplifies the pre-foundation study. Therefore, the main focus should be on stratigraphic characterisation to determine the suitability of the support and to ensure the correct transfer of loads.
