Pipe penetrations through geomembranes

Q&A: GMA Techline | June 1, 2022 | By:

Q: Is there a recommended detail that you can provide or point me toward for pipe penetrations through geomembrane single and double liners?

A: You should review American Society for Testing and Materials (ASTM) D6497 Standard Guide for Mechanical Attachment of Geomembranes to Penetrations or Structures. It is excellent, with three tried-and-true standard details that address pipe penetrations through geomembranes. Please note, most of the details in the standard suggest using prefabricated, factory-manufactured boots for this purpose.
