GAS TRANSPORT COMPOSITE BARRIER

摘要

A method (10) of minimizing vapor transmission from a constructed permeability control infrastructure can comprise forming (12) a heterogeneous hydrated matrix within the constructed permeability control infrastructure, the constructed permeability control infrastructure comprising a permeability control impoundment defining a substantially encapsulated volume. The heterogeneous hydrated matrix includes a particulate solid phase and a continuous liquid phase which is penetrable by a vapor having a permeation rate. The constructed permeability control infrastructure is operated (14) to control the permeation rate by manipulating (16) an operational parameter of the constructed permeability control infrastructure. Additionally, the vapor can be impeded during operating sufficient to contain the vapor within the constructed permeability control infrastructure.
