I think that stuff actually is Great Stuff brand...it's just black......and priced for pond folk.

Actually having used both, I can say that it's not as brittle as the insulation kind is.

Okay, you smart, me dumb, you win.

Maybe I should have said....
"I wonder if the addition of the pigment changes the consistency"
.....would that have been less likely to have offended you?

There is also a product for ponds which works similarly to that Great Stuff spray on insulation. It's called Waterfall Foam Sealant. It's used for adhering large rocks and stones to pond liners or pre-fab ponds. We used it in our pond to hold rocks in place that our waterfall would have knocked down into the pond and it held through 5 winters....it was still holding well when we took the pond out last summer. It's really adhesive, and made to make sure that what it was sprayed onto STAYED sprayed and held. It was also non-toxic to our Koi, and they can be very sensitive to chemicals. We would keep the pond running all year in our frigid Wyoming Winters with a simple stock pond heater, and not even ice or temperature changes affected the seals. Wild birds used the water in the pond all year round for drinking with no effect. Good stuff. Maybe that would work for putting that type of drain in a pre-fab pond....unless I missed the whole point of the posts because I lost track of what I was talking about. <sigh> Been that kinda day. If that's the case, please feel free to disregard this post.

That does make sense. Based on all of the reading/research that I've done, pretty much nothing sticks to HDPE. It's one of the positive properties of the material in most cases. I will probably look into using that stuff to try adhering rocks or something to the top portion, but the fact that I could only find one little sliver of info about successfully adhering anything to HDPE, and that was with a specialty two part epoxy from the plastics purveyor makes me believe that it probably sticks much better to the EPDM liners than HDPE. Wow... that was not meant to be negative at all. I totally get that we probably overbuilt this, but that's kinda how I roll.

Most of the thicker pond liners are edpm rubber, same as rubber membrane roofing materials....there are some thinner poly-xxx type liners....you can get 'pond' liner alot cheaper if you buy the roof material, as long as it's not anti algaae/fungus treated

I did a long stint researching ponds and built a water garden.
Used to run a plastic extrusion machines LDPE, HDPE, vinyls, styrene.....used to be able to tell them apart 'using the tooth'.

Can you elaborate on this a little? What specifically is it called?

Quote: Artt is saying many pond liners are made from EDPM (Ethylene Propylene Diene Monomer) and this is the same material they use for roofing for flat roofs.. It comes in rolls if you buy it at Lowes or home depot but you can order it specifically the right size for your project.... If you are covering a 20 x 20 roof or carport.... The deal is some of it comes with chemicals to kill fungus and algae. You can order it without.

The roll stuff comes 10 feet wide by 50 feet long. That would be perfect for a long pond.... The interesting thing is the stuff can come with adhesive on the back.... Gosh a person could take advantage of that to make a wood lined strucutre and stick the material down.

Thanks I'll have to look it up.

I am intrigued by this. I'm planning on doing some sort of aquaponic setup with the duck waste to grow kale and stuff to feed back to the ducks, and I'm thinking this type of liner might be perfect inside a box for the grow raft area. That is, until building it turns into a $200 project that is finicky and leaks all the time, when I could have just spent $80 on a 100 gallon rubbermaid trough.

OK, so not my invention, I copied it from this guy's autodoor design, I fell in love with the latch system the moment I saw it a year ago.

So I needed a latch for the pop door on my coop partition that worked from 6 feet away and this fit the bill perfectly, it operates with a rope.
Got it built a couple days ago and it worked great on the bench, installed it today and am thrilled.

Should have made the frame taller, this is the same pop door frame on another part of my coop that has a different latch system.
But this part of the coop is for junior birds so it'll work fine.

Simple mechanisms like this are just my favorite things!!!
