Estudio geotécnico in Liendo

In Liendo, the geological substrate is composed mostly of sandstones, conglomerates and flysch, accounting for approximately 86% of the materials present, while limestones and dolomites make up almost 10%. This predominance of detrital materials generally provides a high bearing capacity and allows conventional shallow foundations, provided that levels of alteration or excessive fragmentation are not located. The low permeability typical of these lithologies may generate superficial perched aquifers, which must be assessed during the design phase in order to prevent dampness problems in basements or semi-basements.

Seismicity in the area is very low, with only one recorded event in the last 30 years and a low maximum magnitude, so the seismic influence on structural design is minimal. However, given the percentage of limestones and dolomites, there is a possibility of karst processes developing, so it will be essential to check for voids or cavities before defining the foundation in order to avoid unforeseen differential settlements. The absence of clayey soils rules out the risk of expansiveness, and the main controlling factor is verification of the karst.
