Using a geomembrane liner contributes to the stability of tailings dams by providing a barrier that prevents water infiltration and seepage. By lining the base and slopes of tailings dams, geomembranes effectively isolate the tailings material from the surrounding soil and groundwater, reducing the risk of liquefaction and slope instability.
This containment helps maintain the structural integrity of the dam, preventing erosion and internal erosion that could lead to breaches or failures. Geomembranes also aid in controlling the moisture content within the tailings, minimizing the potential for pore water pressure buildup and enhancing the stability of the dam.
