Geotechnical study in Lodosa

In Lodosa, sandstone, conglomerates and flysch units predominate as the geological substrate, often accompanied by gypsum-bearing formations and occasional areas of gravel, compacted sands and fine deposits. The high presence of gypsum, anhydrite and salts implies a dissolution risk that directly affects bearing capacity and the durability of foundations, which is why verifying the stability of these materials is essential before defining the structural support system. The existence of highly productive aquifers and highly permeable soils also requires a detailed analysis of drainage and possible fluctuations of the groundwater table when planning foundations.

Lodosa exhibits high seismicity, with more than 200 recorded events over 30 years and an estimated maximum earthquake magnitude of 5.2, which makes it necessary to consider specific criteria for earthquake-resistant design in any structural project. On the other hand, the presence of karstic formations must be carefully assessed through an exhaustive geotechnical study, since the appearance of cavities can radically condition the stability of the works. The non-clayey substrate rules out the risk of shrink-swell, so the most relevant constraint in this area corresponds to gypsum-bearing materials and the potential development of karstification, both critical for the planning of safe foundations.
