Estudio geotécnico in Torregrossa

In Torregrossa, the subsoil is formed fundamentally by compact gravels and sands along with sandstones, conglomerates and flysch. These materials exhibit excellent bearing capacity, facilitating the design and construction of shallow foundations. The low overall permeability of these formations, although it may give rise to superficial aquifers in certain areas, limits the presence of significant groundwater, which contributes favourably to the stability of the foundations in most cases.

Seismic activity in the municipality is very low, with minimal records and low magnitudes, which minimises the requirements in terms of structural calculations for earthquakes. The absence of karst and the predominance of a non-clayey substrate eliminate both the risk of instability associated with dissolution and problems linked to the ground’s expansiveness. Therefore, the main factor to be assessed in local geotechnical studies lies in the appropriate characterisation of the compactness and bearing capacity of the granular formations present.
