Estudio geotécnico in Rafal

In Rafal, geotechnical studies show that the predominant substrate is made up of fine sands and silts. These types of soils have variable bearing capacity but, generally, provide acceptable conditions for shallow foundations provided that the appropriate checks for compaction and moisture are carried out. The presence of formations with very low permeability may promote ponding during periods of heavy rainfall and under conditions of high groundwater levels, which is important to take into account when choosing the type and depth of the foundation.

Seismicity in Rafal is at a notable level, with 52 registered events over the last 30 years, although the maximum magnitude (Mmax 3.4) is moderate and does not severely affect ordinary structural design. As the substrate is non-clayey, the risk of expansiveness is ruled out, which simplifies the foundation stability studies. Control of any possible rise in water and verification of the compactness of the silty soils are the main factors to be managed in the geotechnical study for this municipality.
