Estudio geotécnico in Madrigalejo

In Madrigalejo, the predominant geological substrate consists of slates and schists, materials that cover almost the entire area of the municipal surface. These metamorphic rocks have low permeability, which affects the limited capacity for vertical drainage and may influence the behaviour of the groundwater in localised areas. For building projects, the bearing capacity of these materials is usually sufficient for conventional foundations, provided that masses of water are avoided and the continuity of the competent substrate is confirmed through the relevant geotechnical study.

Seismic activity in Madrigalejo is notable, with 56 events over 30 years and a maximum value of moderate magnitude (Mmax 3.1). This circumstance recommends a detailed geotechnical analysis which, although it does not require exceptional structural design measures, may still influence the choice of foundation type depending on the ground’s dynamic response. The non-clay substrate rules out expansivity risks, so the dominant behaviour to consider is the low permeability of the slates and schists.
