Subject: Optimum height? ASTM D4873 covers the identification, storage, and handling of geotextiles. However, there is no guide on what the optimum height should be for stacking rolls of material. This is often covered by statements to the effect that this should be “specified by the manufacturer.” All well and good, but surely there needs to be a standard that defines what the best practice is. Are there any such guidelines?
Reply: In the waste containment QA/QC technical guidance book by Daniel and Koerner (ASCE Press, 2007, ISBN 0-7844-0859-9), there is a section regarding geotextile storage at a field site. Item 3 (page 256) states, “The roles should be stacked in such a way that cores are not crushed and the geotextile is not damaged. Furthermore, they should be stacked in such a way that access for conformance testing is possible.”
Hope this helps you.
