Estudio geotécnico in Celrà

In Celrà, soils formed by compacted gravels and sands predominate, complemented by outcrops of slate and schist, which generally provides a good bearing capacity to the ground. The occasional presence of granite, gneiss and other igneous materials suggests a fairly firm base, although the existence of fine sands and silts in some areas indicates that it may be necessary to specify the compactness before selecting the optimum foundation depth. The formations present require studying the continuity and uniformity of the strata to avoid differential settlement, especially considering the low surface permeability and the possible presence of aquifers at depth.

The municipality exhibits very low seismicity, with hardly any recorded event every 30 years and a low maximum magnitude, so this aspect does not significantly condition the structural design. However, since there are formations of limestones, dolomites and marbles, the possible presence of karstification must be verified before constructing, as this constraint may cause local instabilities or subsidence. As the substrate is not clayey, it rules out the risks associated with expansivity. Therefore, reviewing karstification is the main geotechnical factor to control in Celrà.
