Estudio geotécnico in Sierra Engarcerán

In Sierra Engarcerán, the geological environment is dominated by the presence of limestones, dolomites and marbles, which constitute more than 76% of the shallow substrate. These materials provide a notable bearing capacity, which generally facilitates the use of shallow foundations. However, the occasional presence of fine sands, silts and gravels must be assessed locally, especially in the vicinity of water bodies, in order to avoid unwanted settlements or problems associated with the loss of fines in highly permeable aquifers.

Seismicity in the municipality is very low, with few recorded events and a low maximum magnitude, and therefore the seismic influence on structural design is minimal. The existence of important aquifers in carbonate rocks and the possibility of karstification make it essential to verify the presence of cavities or unstable areas before designing the foundation, since karst can generate unexpected subsidence. The non-clayey substrate rules out expansivity-related risks; therefore, the main geotechnical constraint will be the detailed assessment of karst in limestone and dolomitic areas.
