Estudio geotécnico in Olesa de Bonesvalls

In Olesa de Bonesvalls, soils predominantly consist of limestones, dolomites and marbles, which provides a highly competent bedrock substrate for foundations. These materials, characterised by their compactness, generally offer good bearing capacity, although the occasional presence of sandstones, conglomerates and flysch requires verifying the uniformity of the ground to optimise the structural design. In depth, these formations may host significant aquifers, but at the surface they usually show low permeability, influencing excavation and drainage conditions.

Seismicity in the municipality is moderate, with 29 events recorded over the last 30 years and a maximum magnitude of 2.8, so the seismic impact on the structure is limited. However, the presence of karst in the carbonate materials makes it essential to carry out thorough ground investigation before any foundation project, to rule out voids or unstable areas that could affect structural safety. The non-clayey substratum rules out expansiveness risks, with karstification being the main geotechnical factor to be assessed in Olesa de Bonesvalls.
