Estudio geotécnico in Las Palmas de Gran Canaria

In Las Palmas de Gran Canaria, the predominant geotechnical substrate is made up of granite, gneiss and other resistant igneous rocks, accompanied to a lesser extent by sandstones, conglomerates and flysch formations. These materials generally present a high bearing capacity and provide an optimal basis for shallow or semi-deep foundations, provided that their compactness is verified and that there are no localised alterations. The presence of aquifers with moderate permeability and yield may influence the choice of foundation level and the design of the peripheral drainage, to prevent moisture-related impacts.

Seismicity in the municipality is very low, with only one event classified in the last 30 years and a maximum magnitude of 1.5, so it does not represent a significant limitation for structural design. There are no signs of karstification or risks associated with expansivity, given the predominantly non-clayey nature of the substrate. Therefore, the main geotechnical constraint in Las Palmas de Gran Canaria lies in controlling the quality of the local rock mass and managing groundwater levels.
