Estudio geotécnico in Chantada

In the municipality of Chantada, soils formed by sandstone, conglomerates and flysch predominate. These characterise the main geological landscape and typically present a sufficient bearing capacity for most shallow foundations. Shales and schists, although less frequent, may occur locally and may require additional considerations regarding stability against erosion and fracturing. The presence of groundwater is residual and does not significantly affect the choice of foundation type, but the generally low permeability of the ground should be taken into account for drainage management in the vicinity of the works.

Seismic activity in Chantada is moderate, with twelve recorded events over the last thirty years and a maximum magnitude of 2.6, indicating low seismic requirements for structural design. The non-clayey substrate rules out the risk of expansivity, allowing foundations to be designed without the need to adopt special measures against swelling. In this context, the main technical constraint is the low permeability of the ground; therefore, the management of groundwater and surface water must be carefully considered during the design and execution phase of the project.
