How to Install Rebar in Concrete Footings
- 1). Excavate and install the building's concrete forms according to the architectural design. Depending on the average winter temperatures, this usually requires builders to dig a trough about 24 inches wide and 4 feet deep, then line it with two planes of 1/4-inch plywood that are 8 inches apart.
- 2). Place a web of rebar into the middle of the two pieces of plywood. At the end of one web, insert another web, then wire the two webs together with a generous amount of steel wire.
- 3). Continue inserting new webs and wiring them together until the entire footing has been lined with rebar.
- 4). Cut excess rebar from the top of the footings with a cutoff saw about 6 inches below the planned top of the footing.
- 5). Wrap one end of a piece of steel wire around nails in the footings about every 4 feet, then wrap the other end around the rebar. This will hold the rebar in place when the concrete is poured into the forms.
- 6). Pour the concrete into the forms and smooth according to the building's architectural design and allow the concrete to cure.
