Estudio geotécnico in Reinosa

In Reinosa, a substratum formed by sandstones, conglomerates and flysch predominates, materials that constitute the basis for most foundation projects in the area. These sedimentary formations generally exhibit favourable bearing capacity for conventional buildings; however, the occasional presence of gypsum, anhydrite and salts implies a potential risk of dissolution that could affect the stability of foundations if the appropriate precautions are not taken. Fine sand and silt layers, although infrequent, require case-specific investigation due to their possible lower bearing capacity, particularly in the presence of surface water bodies.

Seismicity in the municipality of Reinosa is notable, with 145 events recorded over 30 years, although the maximum magnitude of the events does not exceed 4, which implies that, although seismic action must be considered in structural design, the requirements will not be as stringent as in areas with higher magnitudes. The substratum is not predominantly clayey, so the risk of expansiveness is ruled out. Given the existence of materials susceptible to karst processes, it is essential to verify the presence of cavities before defining the foundation solution; this factor, together with the risk of dissolution due to gypsum or salts, is the main local geotechnical determinant.
