Estudio geotécnico in La Cellera de Ter

In La Cellera de Ter, soils formed by limestones, dolomites and marbles predominate, accounting for more than 90% of the substrate, while slates and schists are in the minority. This composition implies generally high bearing capacity, which facilitates the adoption of shallow foundations, except in specific areas where the presence of slates may lead to a slightly lower resistance. The low permeability of these formations limits the risk of dragging or dispersion of fines, although shallow aquifers may occasionally occur and require site control.

As for seismicity, La Cellera de Ter is located in an area with very low seismic activity (2 events over 30 years and a maximum magnitude of 1.6), so this factor does not constitute a significant constraint for structural design. The risk of expansivity is ruled out thanks to the absence of expansive clays in the dominant substrate. Therefore, the main determining factor in this municipality is the need to verify the foundation according to the continuity and quality of the carbonate rocks, with no risks associated with karstification or expansivity.
