Estudio geotécnico in Llers

In Llers, calcareous, dolomitic and marble substrates predominate, alongside deposits of compact gravels and sands, as well as some formations of sandstones, conglomerates and flysch. These materials form a mainly competent ground for foundations, with good bearing capacity, although the karstic formations and the low near-surface permeability require special attention during the preliminary works. The possibility of deep aquifers must be taken into account in the design of deep foundations to ensure long-term stability.

Seismicity in Llers is very low, with only 3 registered events over 30 years and a low maximum magnitude, so this aspect does not represent a relevant technical constraint. However, the presence of karst requires thorough verification before building foundations, as hidden cavities may exist with the potential to compromise structural safety. Since the substrate is not clayey, any risk associated with expansiveness is ruled out. The main constraint in this municipality is therefore the possible presence of karst processes in calcareous areas.
