Estudio geotécnico in Lanjarón

In Lanjarón, substrates of slate and schist predominate, characterised by their low permeability and compactness, which favours a good bearing capacity for most buildings. Limestone, dolomite and marble occur occasionally; areas with greater hardness and localised variations in ground behaviour may be identified, although in general shallow foundations are feasible since these are not clayey substrates.

Seismicity in the municipality is moderate, with 11 recorded events every 30 years and a maximum magnitude of 3, which implies controlled structural levels but no conditioning factors for design. However, the presence of carbonate formations requires verifying the possible existence of karstification before starting any foundations, as this may affect the stability of the support. The absence of clayey soils rules out the risk of expansivity, with the possible presence of cavities of karst origin being the most important geotechnical factor in Lanjarón.
