Estudio geotécnico in Navas del Madroño

In Navas del Madroño, the geological substrate is predominantly dominated by granite, gneiss and other igneous rocks, accompanied by schists and slates in proportions that are also significant. These lithologies, which are hard and competent in nature, provide a high bearing capacity, making them ideal for shallow foundation solutions provided that adequate near-surface compaction is verified. The permeability of these materials is low, although in certain areas shallow aquifers may occur, which may require additional attention in the management of groundwater during the execution of the works.

The seismic hazard in this municipality is very low, with only one recorded event in the last 30 years and a very low maximum magnitude, which minimises the need for additional requirements in structural design due to this factor. The fact that the substrate is non-clayey rules out the risk of expansivity and there are no signs of karst phenomena that could condition the foundations. The main aspect to consider in the geotechnical study will therefore be the appropriate characterisation of the fracturing and alteration of the underlying bedrock, especially with regard to its interaction with water.
