Waterproofing a Heterogeneous Soil (Sand-Bentonite) with Water and Leachate

The existence of stocks of industrial waste, and household garbage on the surface poses major environmental problems. In Algeria, this problem begins to be felt, and becomes a concern of the environmental and geotechnical specialists, who care for the achievement of the sustainable developments. The primary interest for environment protection increases the requirement of high quality and reliable sealing systems, which the qui main characteristics Sought are a maximum dry density of the compacted sand mixtures/bentonite and a low hydraulic conductivity (K ≤ E-9 m/s) with water first and then with heavy metals (cadmium) to minimize leakage using a small percentage of bentonite.
