Estudio geotécnico in Valga

In Valga, the geological substrate consists mostly of sandstones, conglomerates and flysch, which exhibit good bearing capacity and are suitable for most conventional foundation systems. In smaller proportions, there are also shales, schists, as well as some areas of fine sands and silts; the latter require specific attention regarding possible differential settlements and drainage. The occasional presence of masses of water reinforces the need to check groundwater levels in the preliminary stages of the geotechnical study, although the predominance of low-permeability materials limits the extent of deep aquifers.

The recorded seismic activity in Valga is very low, with only one event in 30 years and a maximum magnitude of 2.1, so it does not constitute a relevant constraint for structural design. No karst development is presented and the non-clayey substrate rules out the risk of expansivity, favouring the long-term stability of the ground. The main aspect to consider in the geotechnical study is the correct characterisation of specific zones with finer materials or the presence of water, thereby ensuring the appropriate selection of the foundation type.
