The frequency of application of the adsorption layer method for preventing the diffusion of heavy metals from naturally contaminated soil has been increasing at construction sites in recent years. However, there is concern that break down of the adsorption layer may allow heavy metals to directly permeate into the ground causing contamination. We developed an adsorption layer method incorporating a water shielding layer for improved performance. The water shielding layer and the adsorption layer were installed at the bottom of an embankment, and leachate from contaminated soil was guided to the foot of slope.
