This is the concept behind the plastic that is on the ground in front of the wall... My idea last year after we had a blow out... does anyone think it actually does anything?

It will help at your joints on the plywood and help keep them dry. The real deal with the plastic is erosion from the moving water on a clay dike. If you had a blow-out it was from lack of bracing. You guys still need a lot if the water comes up more than 3' on the plywood. Look at some pictures of plywood concrete forms and you will see what I was talking about.

ps. I did stop by and someone didn't want any advice today. Lunch was more important at the time.:icon_scratch:

6 mil... lol i guess i never really though about 6 mil not meaning 6mm... anyways...
Do you think it is helping with any of the water pressure? I realize it is helping with erosion now that you say that.

Use it if you haven't in the past and the seams were leaking. It won't do a thing for the pressures.

I dont think that the plastic draped over a wood wall is going to help with pressure, but I am not an expert.

the horizontals are the walers

Seams weren't leaking, just had a large blowout in front of the wall and the water spewed out inside the dike. It almost took us out last year. we piled a shit load of bags on it and slowed it down enough for it to freeze(thank god it was like 10 degrees outside that night)

No, the plastic on the ground protruding from the wall... We were trying to stop the downward force of the water and preventing water from taking out the ground below the wall/planter

The blow-out was the soil underneath getting pushed in?

The soil never got pushed under the wall, the water pressure made its way through the soil, under the wall, under the planter and surfaced inside the dike...

the plastic out onto the ground wont help much in the way of keeping water from coming up behind the wall but it should help keep soil from eroding out from under it. bag up behind the wall a bit and add some weight like you did before. or bag the entire ground to combat the pressure?

was the blow out near one of the holes for your pumps? you could have been pumping sediment out from under your wall to cause the failure...

it was near a pump hole, but when the water went down, there was a huge hole in the ground Outside the wall. We bagged over the top of where the big hole was and back filled it with clay also.
