Estudio geotécnico in Coles

In Coles, the geotechnical substrate is dominated by sandstones, conglomerates and flysch, with a scarcely significant presence of shales and schists. These lithologies give the ground good stability and mechanical strength, promoting high bearing capacities for shallow foundations. In addition, permeability is low, although some shallow aquifer may exist in certain strata, a point to be taken into account during excavation and the control of groundwater.

Seismic activity in Coles is very low, with only about 8 recorded events over 30 years and a maximum magnitude of 2.1, so the seismic influence is practically negligible for structural design. The non-clayey substrate rules out any risk of expansivity. In conclusion, the main geotechnical consideration for the municipality is the proper characterisation of the strength of the sandstone and conglomeratic substrate, as well as the possible management of shallow aquifers during construction.
