Estudio geotécnico in Vallmoll

In Vallmoll, the predominant substrate is composed of sandstones, conglomerates and flysch, accompanied by gravels, compacted sands and a significant presence of fine sands and silts. This combination generally provides a medium to good bearing capacity, allowing for direct foundation solutions in most cases; however, it is recommended to check the homogeneity of the strata and to avoid levels of fine sands and silts if they present low density or high moisture content. It is important to consider that these formations are usually poorly permeable at the surface, although they may host aquifers at greater depth.

Seismic activity in the municipality is very low, with just 5 events over 30 years and a maximum recorded magnitude of 1.9. This indicates that the impact of seismic movements on structural design is practically negligible and, consequently, does not represent a relevant constraint. Likewise, the non-clayey substrate rules out the risk of expansivity, enabling a safe foundation approach without critical geotechnical constraints associated with movements of clays or the dissolution of soluble materials.
