The impermeable coating treatment is an original technology which coats solid wastes by a particle unit with the impermeable material containing water-absorbing polymers. The elution of attached substances on the surface of soil particles such as heavy metals will be suppressed, because each particle of soils is coated with impermeable materials uniformly. Furthermore, since the swollen impermeable coating material by absorbing the pore water can fill the void space of solid wastes, the treated soils will be expected to improve their water interception performance. In order to utilize solid wastes as soil improvement materials, impermeable treatment materials and so on, this study evaluated the key properties such as the elution of heavy metals and alkaline, a water permeability, and the relationship between swelling and upheaval of treated soils with the impermeable coating by laboratorial experiments.
