Geotechnical study in Canals

In Canals, limestone, dolomite and marble soils predominate, representing more than half of the near-surface substrate. These materials usually provide a very good bearing capacity, facilitating direct foundations with conventional solutions. In a secondary way, fine sands, silts and, to a lesser extent, gravels are also found; these may require additional assessment of the homogeneity of the bearing layer if they are to be used to support foundations, making it preferable to found on well-compacted zones or directly on the calcareous bedrock.

Seismicity in the municipality of Canals is very low, with a low frequency of events and a maximum magnitude below 3; therefore, seismic risk does not represent a relevant constraint for structural design in the area. The non-clayey substrate rules out the presence of expansive soils as a geotechnical risk. However, the presence of carbonate materials makes it essential to check for the possible existence of karst phenomena, since these can affect the continuity and strength of the ground; therefore, verification of voids or cavities will be decisive before defining the final foundation.
