Estudio geotécnico in León

In the municipality of León, the geotechnical subsoil is overwhelmingly dominated by slates and schists, which account for more than 90% of the ground materials. These formations generally provide a competent foundation for shallow foundations, although their low permeability may limit drainage and the ability to dissipate surface water or infiltrate local aquifers. Limestone and dolomites, present in a smaller proportion, introduce the possibility of interbedded zones in which bearing capacity may vary locally, meaning that detailed stratigraphic assessment is essential in order to optimise the foundation design.

León shows a high level of seismic activity, with an approximate record of 200 events over the last 30 years and a maximum magnitude of 4.7, which necessitates considering seismic actions in the structural calculations. The presence of limestone and dolomitic blocks also implies the possible occurrence of karst-related phenomena, making it essential to verify these before any foundation is built in order to avoid the risks of subsidence or instability. Since the subsoil is for the most part non-clayey, the risk of expansivity is ruled out; in this context, the main geotechnical constraint in León is the combination of seismicity and possible karst cavities.
