Estudio geotécnico in Buitrago del Lozoya

In Buitrago del Lozoya, the dominant geological substrate is composed of slates and schists, present in almost all soils within the municipality. These materials, characterised by low permeability and moderate internal cohesion, usually provide adequate bearing capacity, albeit heterogeneous, which requires point-by-point assessments to optimise foundation design. The usual impermeability of these formations favours structural stability; however, surface aquifers may occur due to alteration, and these must be taken into account in geotechnical studies.

As regards geodynamic aspects, seismicity in Buitrago del Lozoya is very low, with only 5 recorded events over 30 years and a moderate maximum magnitude of 3, which minimises the influence of earthquakes in the usual structural calculations. The non-clayey substratum eliminates the risk of expansivity, allowing greater confidence when selecting foundation systems. The main geotechnical issue to assess is the local variability in the texture and quality of slates and schists, as well as the possible presence of surface water in altered horizons.
