Geotechnical study in Villalba del Alcor

In Villalba del Alcor, formations of limestones, dolomites and marbles predominate, accounting for more than 65% of the soils. These are materials of high stiffness and generally good mechanical characteristics. The presence of slates and schists provides areas of lower strength, although they are usually stable for conventional shallow foundations. The low overall permeability of the ground suggests good performance against seepage, but in fractured zones there may be shallow aquifers. The bearing capacity of these lithologies is generally favourable for most structural typologies.

The recorded seismicity is very low, with barely 4 events over 30 years and a maximum magnitude of 2.3, which places this factor outside the priority constraints for structural design. Since the bedrock is non-clayey, the risk of expansiveness associated with clayey soils is ruled out. The absence of karst risk also simplifies the feasibility of the foundation. In this municipality, the geomechanical properties of the limestone and dolomitic substrate are the main criterion to take into account when planning a geotechnical study.
