Estudio geotécnico in Algarrobo

In the municipality of Algarrobo, slate and schist predominate as the substrate, accompanied by the occasional presence of fine sands and silts. This lithological combination gives the ground a high degree of stability, with good bearing capacity in areas of slate and schist, although areas with fine sands and silts may show some compressibility and lower strength. The low permeability typical of these materials should be taken into account in the management of surface water and drainage, particularly in shallow foundation and retaining structure projects.

Seismicity in Algarrobo is very low, with a single event over three decades and a maximum magnitude of 1.5, which implies a minimal impact on structural design. The absence of an clayey substrate eliminates the risk of expansivity, making it easier to select conventional foundation solutions. In this way, the main factor to consider in geotechnical studies will be the local heterogeneity of the materials, as well as the accurate assessment of surface permeability.
