Estudio geotécnico in Gurb

In Gurb, predominantly white and soft expansive clays occur, accounting for approximately 75% of the soils, whereas the remainder corresponds to sandstones, conglomerates and flysch. These materials generally have very low permeability, although shallow aquifers may be found in certain areas. From a geotechnical point of view, low permeability limits infiltration, favouring overall stability, although the clays, due to their texture and plasticity, condition the bearing capacity. Care is recommended when selecting the type of foundation, adapting it to the presence of potentially compressible materials.

Seismicity in the municipality is very low, with only one significant event recorded in the last 30 years and a low maximum magnitude, so it does not constitute a relevant constraint for structural design. No karstification processes are identified and, although clays are present in a high percentage, the analysis indicates that the dominant substrate at depth is not clayey, so the risk of expansivity is ruled out at geotechnical level. The main factor to control will be the accurate identification of the thickness of soft clays in order to determine the optimum foundation depth.
