I have been using the EPDM 45 mil rubber for the past 3-4 seasons and
from what I can see on the internet, it appears to be 'the choice' for
water gardens and ponds. During my search I came across a company
https://www.btlliners.com/ that sells a liner called PPL-24. Does
anyone out there have any experience with this material? It "looks"
good and is about $200.00 less than the same size liner in EPDM.
Thanks!
