Interface friction info

Question

Is there any interface friction information available between PVC to RCSPE layers?

Scott,

We have a rather large database of interface friction values (as do others) but not for that specific combination of geomembranes. That said, the PVC values are inherently quite high and the undulations from the scrim in the CSPE are an advantage so I imagine the value is reasonably high. Just what, I don’t want to venture a guess.
