Estudio geotécnico in Viso del Marqués

In Viso del Marqués, the ground is predominantly made up of slates and schists, which account for more than 90% of the substrate. These materials are characterised by very low permeability, which greatly limits the flow of groundwater and governs the formation of shallow aquifers. The bearing capacity of these soils is usually good for conventional buildings, although it is advisable to carry out a detailed geotechnical study to define the most suitable foundation type in accordance with the local variability of the rock and the possible presence of weakness planes.

The area shows very low seismicity, with only 8 registered events in the last 30 years and a maximum magnitude of 2.6; as a result, seismic risk is practically non-existent and does not represent a significant restriction for structural design. The non-clayey substrate rules out the risk of expansivity, making it easier to choose construction solutions. In conclusion, the main geotechnical constraint in Viso del Marqués is the low permeability and the lithological nature of the substrate, rather than risks associated with expansive soils or seismic activity.
