Estudio geotécnico in Guissona

In the municipality of Guissona, the geological substrate is mainly made up of sandstones, conglomerates and flysch, which account for more than 80% of the materials found in the area. These soils generally provide good bearing capacity and allow the use of shallow foundations, provided that the thickness and compaction are adequate. In smaller proportions, it is possible to find fine sands, silts and carbonate formations such as limestones, dolomites and marbles; although the latter are marginal and the overall behaviour with respect to stability and deformability remains favourable for building development.

Seismicity in Guissona is very low, with only a single recorded event in the last 30 years and a clearly low maximum magnitude, which minimises the need to incorporate seismic requirements into the design of foundations. No significant cases of karstification have been reported, and the presence of a non-clayey substrate rules out the possibility of problems associated with soil expansivity. In short, the main geotechnical constraint in Guissona usually lies in assessing the compaction and continuity of the dominant materials.
