This guide discusses the relevancy of applicable test methods, including the materials and conditions involved, in obtaining the vapor transmission in geomembranes. This guide does not purport to critique barrier system permeability, nor does it address transmission through seams. The guide assumes the material being examined exhibits Fickian diffusion behavior. The tests discussed here evaluate gas and vapor transfer through semi-permeable and permeable geomembranes. The data is important for design of containment systems.
