How to Make Your Own Rebar Anchors

When a concrete structure is poured in two or more steps, such as pouring a concrete floor and foundation walls for a home, the second concrete pour doesn't seal onto the first. Because the first poured section is dry and cured, the second will only set on top of the first. In this case, the seam has no structural strength. Therefore when concrete is poured in multiple steps, the first step is seeded with rebar. When the second step is poured, the wet concrete hardens around the rebar, and mechanically fastens the two pieces of solid concrete together.

Metal rebar
Bench vice
1 inch diameter iron plumbing pipe, 36 inches long
Hack saw
Safety gloves

Instructions

- 1
  Cut the rebar into short sections. For a simple rebar anchor, cut the rebar into 12 to 14-inch-long pieces.
- 2
  Place one end of the rebar into a bench vice and tighten the vice securely on the bar.
- 3
  Slip the iron plumbing pipe over the free end of the rebar in order to gain enough leverage to bend the bar. Push on the iron pipe, and bend the rebar into an "L" shape.

  When pouring the first concrete area, insert the short end of the rebar into the wet concrete, oriented so that the long end points upward. When the second area is poured, the wet concrete will harden around the rebar, mechanically fastening the two separate steps together.
