e.shield 205b has been specifically designed to provide maximum redundancy to E.Series systems requiring high performance building protection. Installed on underslab and shoring assemblies, e.shield 205b exemplifies EPRO’s redundant field installed composite design concept by combining a protective geotextile, a layer of high density polyethylene (HDPE), and bentonite into one sheet that serves as protection course for the remaining E.Series components. When combined into one system, this provides extraordinary protection from water, methane, and chemical vapor intrusion.
