Estudio geotécnico in La Línea de la Concepción

In La Línea de la Concepción, geotechnical studies usually find a substrate formed mainly by sandstones, conglomerates and flysch, together with appreciable proportions of limestones, dolomites, marbles and compacted gravels. This composition ensures, in most cases, satisfactory bearing capacities, facilitating direct foundation options on competent natural ground. Urban made-up ground must be analysed particularly, as it may present heterogeneities and a lower bearing capacity locally.

The seismicity recorded in this municipality is very low, with a low maximum magnitude, which minimises the relevance of seismic risk in structural design. In addition, the absence of expansive clayey materials and of karst phenomena, together with a non-clayey substrate, makes it possible to rule out problems of expansiveness and collapses due to dissolution. The main geotechnical limiting factor stems from the possible presence of made-up ground and the point-by-point verification of the quality of the supporting ground.
