Estudio geotécnico in Parets del Vallès

In Parets del Vallès, the predominant substrate is composed of sandstones, conglomerates and flysch, materials known for their good bearing capacity and suitability as a foundation for different types of foundations. In addition, the presence of compact gravel and sand strengthens overall geotechnical stability, facilitating the execution of shallow foundations. The layers of fine sand and silts, although occasional, require localised analysis to rule out losses of bearing capacity in specific areas. Owing to the high permeability of the ground and productive aquifers, it is crucial to take the groundwater table level into account during the planning of the works.

Seismicity in the municipality is very low, with only one minor event recorded every thirty years and a very low maximum magnitude, which minimises this factor as a relevant constraint in structural design. As the substrate is non-clayey, the risk of expansiveness is ruled out, which makes it easier to model and carry out conventional foundations. Consequently, the main geotechnical constraint in Parets del Vallès lies in the hydraulic behaviour of the soils, particularly in relation to the level and control of groundwater, rather than in factors of instability or seismic activity.
