Estudio geotécnico in Móstoles

In Móstoles, soils formed by sandstone, conglomerates and flysch predominate; materials that usually provide good bearing capacities for conventional foundations. This lithological composition, together with the occasional presence of limestones, dolomites and marbles, generally implies adequate stability for civil works and building, provided that investigations are carried out aimed at determining the possible presence of less competent sandy levels interbedded with the strata, or areas with lithological variability that could affect the uniformity of the foundation. However, the extensive surface water body can modify local geotechnical behaviour, making an appropriate hydrogeological characterisation advisable to prevent settlements due to saturation or possible drainage problems.

Seismicity in Móstoles is considered very low, with only 5 recorded events over 30 years and a maximum magnitude of 3, which minimises the impact of seismic risk on structural design. No conditions indicative of karstification are identified, nor is there any presence of materials that would indicate a risk of subsidence due to dissolution. The risk of expansivity associated with dispersed clays in the matrix is low, which reduces the likelihood of structural problems due to ground heave or shrinkage. The most determining parameter for the works in the area will be the proper management of water and the detailed assessment of the predominant strata, as well as the monitoring of possible local variations in the competence of the load-bearing materials.
