Estudio geotécnico in Mollerussa

In Mollerussa, compact gravels and sands predominate, accounting for more than 80% of the subsoil, whereas sandstones, conglomerates and flysch appear less frequently. These materials generally exhibit high bearing capacity and provide good conditions for shallow foundations, minimising the risk of differential settlement. The permeability of these soils is generally low, but they may host localised shallow aquifers; this is an aspect to be taken into account in the excavation stages and in groundwater control during construction.

Seismic activity in the area is very low, with only 3 events in the last 30 years and a maximum magnitude of 2.5, so the seismic risk is practically negligible for structural design. The non-clayey subsoil rules out the presence of expansive soils, which translates into greater stability for the footings. No karst influence has been detected in the municipality, so the main constraint in Mollerussa stems from lithological characterisation and the possible presence of shallow aquifers rather than from adverse geotechnical factors.
