Estudio geotécnico in Almáchar

In Almáchar, a substrate of slates and schists predominates, accounting for more than 70% of the local geology and providing a competent support for shallow and deep foundations. Sandstones, conglomerates and flysch occur occasionally, introducing specific variations in bearing capacity but without compromising overall stability. The marginal presence of gravels, compact sands and limestone deposits does not significantly condition the overall behaviour of the ground, although it is advisable to verify lithological transitions on a case-by-case basis in larger-scale projects.

Seismicity in the municipality of Almáchar is moderate, with 28 recorded events over the last 30 years and maximum magnitudes below 4.0, which minimises the direct seismic risk to projects. As there are no indications of karst or of expansive clayey soils, and the substrate is clearly non-clayey, the problem associated with swelling is ruled out. The main factor to consider in geotechnical studies in Almáchar is the limited permeability of the materials, which requires particular attention to drainage management and control of surface water to avoid problems of water accumulation on site.
