Abstract
Methods and structural configurations of modular barrier systems and cutoff walls used to isolate contaminated soils from the environment in situ. The cutoff walls comprise plastic sheets, preferably of high density polyethylene, inserted in or adjacent to dense soil (such as bentonite modified) walls, and they are connected to each other with tubular connectors having flaps to which the plastic sheets are connected, preferably by welding.
