Estudio geotécnico in Tegueste

In Tegueste, soils predominate that are composed of sandstones, conglomerates and flysch, which show good mechanical behaviour and generally offer bearing capacities suitable for most shallow foundation solutions. The occasional presence of expansive white or soft clays, however, creates localised situations where a more detailed characterisation may be required in order to rule out differential settlement problems. The existence of permeable layers, associated with perched aquifers or at lithological contacts, may affect the choice of foundation level due to possible variations in the groundwater table.

Seismicity in the municipality is very low, with barely any recorded event in 30 years and a maximum magnitude of less than 2, so it is considered irrelevant for local structural design. Karst conditions also do not constitute a threat in the area. The main constraint for the geotechnical study in Tegueste lies in the point-by-point assessment of the expansivity of the clays where they occur, although the dominant subsoil does not imply significant risks for the foundation.
