How to Make Deck Footings

Direct Pour Post Hole

• 1

  Dig the deck post's footing with a shovel or a post-hole auger. Refer to local building requirements for hole diameter and depth requirements. In general, add approximately 6 inches to the hole's depth for a layer of compacted gravel.

• 2

  Fill the bottom of the hole with approximately 6 inches of gravel and compact the gravel with a tamper. Combine concrete mix and water in a wheelbarrow or concrete mixer according to the concrete manufacturer's instructions.

• 3

  Pour concrete mix into to the hole until concrete reaches the ground's surface. Smooth the poured concrete with a concrete trowel and insert an anchor bolt or post bracket if required by the deck design. Use a level to adjust the anchor bolt or post bracket on both horizontal and vertical planes.

Tube Form Footing

• 4

  Dig the tube form's hole with a shovel or post-hole auger. Excavate the hole according to local building requirements and leave adequate space for gravel beneath the tube form and around the form's sides.

• 5

  Fill the bottom of the hole with gravel according to design specifications or local codes, often approximately 6 inches. Compact the gravel with a tamper. Insert the tube form into the hole, place a level across the form's top and use the level to level the form's top surface.

• 6

  Fill the sides of the tube form's hole with gravel and lightly tamp the gravel with a tamper. Mix concrete mix in a wheelbarrow or concrete mixer according to manufacturer instructions, fill the tube form with concrete and smooth the concrete with a trowel. If required by design, insert an anchor bolt or post bracket into the concrete and level the hardware with a level.

Concrete Pier Footing

• 7

  Smooth the ground's surface with a shovel or rake to create a pad for the concrete pier. Compact the pad by pounding the ground with a tamper.

• 8

  Place the concrete pier atop the smoothed, compacted pad.

• 9

  Place a level atop the pier and use the level to adjust the horizontal position of the pier's top surface. If necessary, remove the pier from the pad, add soil and compact the soil with a tamper to adjust the levelness of the pad.
