Estudio geotécnico in Mallabia

In Mallabia, the predominant geological substrate consists of limestones, dolomites and marbles, accounting for 86.45% of the total, which defines generally high and favourable bearing-capacity conditions for shallow foundations. Sandstones, conglomerates and flysch occur much less frequently. Permeability is usually low or very low, although there may be limited near-surface aquifers constrained by the geological structure itself; such characteristics can limit the efficiency of drainage of groundwater, particularly in works that require basements or deep excavations.

Seismic activity is considered notable in the area, with 94 recorded events over the last 30 years, although the maximum magnitude observed (3.7) does not reach levels of great relevance for structural design, even so it must be assessed in accordance with the applicable regulations. The risk associated with expansive soils is residual, since the substrate is not clayey, eliminating this usual concern in foundations. The main geotechnical constraint in Mallabia lies in the need to correctly characterise the continuity and competence of the rock mass to ensure the feasibility of the foundation, as well as to address any possible levels of confined water.
