Can you leave this form on the post after the concrete is poured or does it need to be removed?
Asked by Roman323 August 18, 2020You can leave it or remove its just anesthetics you can just peel down to below grade, I just set mine so they were below grade, of course if your pouring piers you probably won't have that option.

Can I use this concrete tube as the foundation for the 4 by 4s, where we would bury it 3 feet dee...
Asked by Nessa July 6, 2020Go online and look for a site that can give load calculations for a footer. Width and depth is all depending on the weight you load on it.
Can this be used for 5X5X9ft(h) vinyl posts
Asked by Sam June 13, 2020More details needed for a proper answer. If these are fence posts you will want to bury Part of them underground , 2 feet (24”) in my area. The walls of the hole in the ground will negate the need for the form tube. Form tubes are designed to support weight straight down. A fence needs lateral support ( side to side ; front to back . Getting part of the post anchored under ground is the goal. Also , check instructions on your posts. Some vinyl posts (hollow)are designed to slide down over pressure treated wooden posts. Good luck!
Are 9 of these tubes large enough for a small 12'X16' shed, or should a 12" diameter tube be used ?
Asked by Brent May 30, 2020You should use whatever your local building code dictates.
Do I put all 4 tubes in the ground ?
Asked by Jw May 16, 2020You should only need one tube. You can cut it to whatever length you wish all it does is hold the concrete in that shape. After concrete is set up you can cut the cardboard that is above ground and remove it. But make sure you get the air bubbles out while the concrete is still wet or it will look ugly!
