Estudio geotécnico in Tiana

In Tiana, the ground is dominated by the presence of granite, gneiss and other igneous rocks, which account for more than half of the substrate and ensure a high bearing capacity. Complementarily, compact gravels and sands are present—materials that favour the stability of foundations. These features generally allow a flexible foundation design, since the strength and low compressibility of these soils usually make it easier to use shallow or semi-deep solutions, minimising the need for special foundations.

Seismicity in Tiana is very low, with a single recorded event over 30 years and a low maximum magnitude (Mmax) of 1.7, so it does not constitute a relevant constraint for structural design. As the substrate is predominantly non-clayey, the risk of expansiveness is ruled out and there are no records of karstification. Consequently, the main consideration will be the local characterisation of the granite and any possible alterations to achieve an optimum foundation.
