Form tubes make it easy to pour concrete support footings for mailboxes fence posts decks and other structures. After digging a hole in the correct dimensions for the support slide the form tube into the hole and fill it with concrete making sure the concrete mix is properly consolidated toair pockets and other defects. The concrete willwithin 48 72 hours at which time it will be strong enough to stand up to the strain of construction. Figure out how deep the support needs to sit. Refer to your local building codes to find the depth requirements for the concrete support footings of structures being built in your area. Most of the time footings will need to reach below the topsoil frost line to prevent them from shifting as the ground freezes and thaws.

Dig a hole for the support. Use a post hole digger to scoop out the soil where you plan to place the footing. The hole should be slightly wider than the diameter of the form tube. Having an additional 12 2.55.1 cm of space on either side will allow you to fit the tube in without difficulty.

Fill the bottom of the hole with 26 5.115.2 cm of gravel. For most projects a medium sized all purpose gravel will provide the best results. A layer of gravel will promote runoff which can protect the footing from slipping or weathering and increase its lifespan.

Compact the gravel with a wood post. Use theend of the post to tamp the gravel down flat. This will force the piece closer together offering increased stability and creating a more level base.Brace securely at top, middle and bottom of tube
