I have cut my hdrpe, it has not frayed at all. Edges exposed still in great shape. Handles deer hooves digging into it. Etc.

I researched the diff between epdm and hdrpe when I bought, the hdrep had a lot better ratings burst strength etc. Been 11 yes since I did so a soft recall of all I read.

Just ordered it, I think it will at least be interesting to see what the material is like! ( and oh my gosh is it so much cheaper )

Makes sense, that is also why I used epdm on my main pond, I just saw it around more often. We will have to see how I like this new material!

If you watch some of the larger build series on YouTube, PE type liners are being used all the time.

true but those are relatively flat pitched ponds. as a replacement for clay or bentonite

Check out some of the huge commercial rec ponds that Aquascape has done in the last few years. Several of them are using PE. And 100s of tons of boulders over them.
I would use nothing else, if building another pond, which is not going to happen.

Alright if aquascape is using it in ponds then I am sold. I wonder why they don't use it in smaller backyard ponds as well?

A few reasons I can think of:

1. It’s harder to work with in small ponds with shelves and tight curves.

2. No factory seams to work about.

3. Customers might already know and trust EPDM, so no need to educate the customer.

4. Better profit margin.

I guess that does make sense, I hope its not to difficult for myself to work with in such a small space!

I think it’s worth the trouble when you’re DIYing. Maybe not when you’re trying to run a business, meet tight schedules, and have a crew that is already trained up on EPDM.

most of it will be covered with pea gravel anyway so I am hoping it wont be a huge deal.
