Estudio geotécnico in Torrelodones

In Torrelodones, soils are predominantly formed by granite, gneiss and other igneous rocks, accompanied in smaller proportions by sandstones and conglomerates. This bedrock substrate is characterised by high strength and low compressibility, providing a solid foundation for shallow and deep foundations, with excellent bearing capacity. The limited presence of detrital materials means that differential settlement problems are infrequent, ensuring favourable conditions for both residential and infrastructure developments.

With regard to seismicity, the municipality records only 5 events over 30 years with a maximum magnitude of 3, which indicates very low seismic hazard and no relevant impact on structural design. Since the substrate is not clayey, the risk of expansive soils is ruled out, facilitating the selection of conventional foundation systems. Consequently, the main geotechnical constraint in Torrelodones is linked to the adequate characterisation of the fracturing of the granite to avoid surprises during excavation and to ensure the uniformity of the support.
