A couple things ray, first 85x40 isnt that big. Second you left out a very key element! How deep are you making this bog? If you were to make it 2 or 3 feet deep your going to need something much bigger then 85x40.
Have you followed Carl Mazur's blog about keeping bogs in Canada? He explains how to make a very affordable bog with common stuff. He used a normal drop cloth to line his, I've done the same and it works very well.

In one of his posts, Carl states that it's a double layer of vapour barrier. Vapour barrier is 6 mil, and should last 10 or more years if its not exposed to sunlight.
Carl put down sand, and a thick layer of newspaper to protect the vapour barrier from sharp objects in the ground. It appears as though the barrier is run up the sides, and folded over the top of 2 X pressure treated lumber, and then a 2 X 4 is fastened to the top to hold it in place.
I'm not sure of the depth of his bogs. It appears to be about 11-1/2" or about 30cm. This is consistent with the kiddy pools the new bogs replaced.
Consider using the drain hardware where the drainpipe passes through the barrier and side. If there's no partial strainer, you'll be able to run a pipe through it. Pre-drill the hole in the side before placing the liner. I'd use silicone seal on both sides of the barrier at the drain. This will protect the barrier from tearing at that point. Use groundcloth around the drainpot to keep the peat in the bog, and out of your drainage system. You can add a float valve in the pot to make it an automatic fill/drain unit.

dToad you have it very very close all on of your points.
I few things to point out, using a 2x6 or a 2x8 works the best for the above ground part as it give you more room to work with as well as an easier time setting up the drainage.
Carl actually has different depths throughout the entire bog, its sorta like a rounded bottom where the edges about a little more then a foot deep but the middle could be almost two feet. Its a cool idea because you can put shallower rooting plants on the edge and deeper rooting plants in the middle while still have a ton of peat and work.
The last thing is based on how he protects the liner. Sand works great and I think he used it on some of his but sand can be a pain to work with the rounded bottoms. Wet down old newspaper and use a couple thick layers and that will work just as well. I like to use old carpet because it protects the liner so well, because of the nature of sand (and a lesser part wet newspaper) suckers from tree or forgotten spring bulbs can weak havoc on your bog without you even realizing it for some time. The carpet will spot anything that tries to grow under your bog without fail.

Tks for the carpet trick H2O. I'm planning to build a bigger bog soon but didn't figured out how to prevent my neighborg's Petasite from pocking through it.

I thought of carpet this morning while driving. I've been kicking myself for throwing it out a couple of months ago.
I like the idea of a sculpted bottom for varying depths.
I'm not ready to build a sunken outdoor bog yet. One day perhaps.

No problem man! It works wonders in the long term, plus you can find it all over the place for free.
Ya the raised edge, sculpted bottom and the "Carl" style drainage works amazing. Without a doubt it's my favorite way to make bogs.

This can all come down to preference.
Personally I use 2:1 peat:16grit silica sand. I find that the 16 grit silica is very important for the mix. Other sand just doesn't cut it when compared to it, plus its 12 bucks for 100lbs the last time a bought it. If you make a deep bog you can make the bottom "reservoir" pure peat or mix it with perlit if you can find it cheap. The idea behind this is that the roots never reach that far anyways and you save the time and money. I also suggest to anyone making a bog to make it deep! It saves water and worry during heat waves.
