Estudio geotécnico in Carballeda de Avia

In Carballeda de Avia, the subsoil is dominated mainly by sandstones, conglomerates and flysch, materials that are characterised by their compact nature and good mechanical strength, which is favourable for the bearing capacity of shallow or semi-deep foundations. The occasional presence of slates and schists provides some heterogeneity, but, in general terms, it does not represent significant limitations for supporting structures. It is important to avoid those specific areas with masses of water to ensure stability and prevent possible differential settlement.

Seismicity in this municipality is very low, with just 4 events in the last 30 years and a maximum magnitude of 2.4, so the seismic consideration in structural design has less influence. Since the subgrade is not clayey, the risk of expansiveness is eliminated, making it easier to select the most suitable foundation type according to the project loads. The main geotechnical factor to take into account will be the accurate identification of impermeable layers or surface aquifers that could affect the durability and stability of the works.
