Estudio geotécnico in Lliçà d'Amunt

In Lliçà d'Amunt, formations of sandstones, conglomerates and flysch predominate, complemented by a significant presence of gravels and compacted sands. As these soils are granular and consolidated in nature, they usually provide good load-bearing capacity conditions for shallow foundations, provided that their degree of compaction and homogeneity are verified during the site investigation. The impermeable or very low-permeability characteristics of the subsoil can affect drainage management on site, although they do not usually limit the ground’s structural capacity for founding buildings for normal use.

Seismic activity in the area is very low, with only 2 recorded events over 30 years and a maximum magnitude of 1.8, which represents a negligible seismic risk in conventional structural design. As the subsoil is not clayey, it also rules out any issues associated with soil expansiveness. In the absence of karst phenomena, the main consideration for the geotechnical study in Lliçà d'Amunt will be the appropriate characterisation of the degree of compaction and continuity of the materials, without critical constraints associated with active geotechnical risks.
