WebDec 25, 2024 · The bottom of the clay cap barrier layer may become somewhat intermixed with subgrade material during construction. Therefore, the effective thickness of a nominal 0.6-m cap is likely to be less than 0.6 m. 3. The compaction procedures for the clay barrier layers are, in many ways, similar to those followed for standard compacted fills as ... Web4.5 A layer of soil (pseudo-component B) of thickness 1 m (see figure) that is located above a clay barrier has been contaminated with a toxic gas (A). The concentration of the gas is initially uniform in the soil and equal to 1.0 x 10-5 mol/cm. The toxic gas will be removed by making pure air flow over the surface of the soil.
