Estudio geotécnico in Bermeo

In Bermeo, sandstones, conglomerates and flysch predominate; soils of a solid nature and with favourable strength for most shallow and semi-deep foundations. To these strata are added limestones and dolomites, materials that are likewise competent, although in a lower proportion. The occasional contribution of fine sands and silts, together with the scarce presence of hard clays, gives rise to local variability in bearing capacity; therefore, a specific borehole is always recommended to properly calculate the allowable stresses and define the most efficient foundation type.

Seismic activity in Bermeo is very low, given the extremely low frequency of events and the maximum magnitude recorded, which minimises its impact on the design criteria. However, the presence of carbonate lithologies (limestones and dolomites) implies the possibility of karst development, a relevant geotechnical constraint that must be verified before executing any foundation, as it may introduce risks of subsidence or underground cavities. The absence of clayey strata rules out any potential for significant expansivity. The most critical factor to consider in Bermeo is the possible development of karst processes.
