I use a LDPE liner that is food grade. I think that it is 30 mil. It has a fiber core that helps prevent stretch and makes it much stronger.

Chris, what kind of liner do you use? Only thing I'm thinking of that might suite such a construction would probably be HDPE. If I do more such beds in the future I may well try your suggestion. (I think the current one is sorted once I get the EPDM liner for it.)<br />
<br />
The billboard liner is definitely not strong enough (I could probably rip it with a fingernail) for such a thing and the EPDM would stretch too much.

You are getting lateral water pressure because the liner is tight in the corners of the trough. If you were to leave a belly(or ark) in the liner at the corner points, the water pressure becomes vertical as the water weight pushes down on the belly and transfers the pressure up to the top of the sides. This will only work with a liner that cannot stretch like PVC will. The liner needs to be firmly attached at the top of the side walls to take the vertical pressure. This is the method that I use.

Very industrious! You certainly don't mess around, the sides look very sturdy now. Hope that leak is repairable.
