| 摘要 |
The invention relates to a barrier for soil structures. The barrier is formed by creating a trench in a soil structure extending from the soil surface to an impervious layer in the soil. The trench is lined with a sheet of impervious material, which may be a fabric carrying a substantially dehydrated sodium-bentonite clay. The trench is especially well-suited for installation around the perimeter of a waste site from which contaminated fluids may be emanating. The barrier and the method of forming the barrier allow a toxic waste site to be easily and completely isolated from adjacent groundwater systems.
