Rebar & Mesh
Concrete has great compressive strength but little tensile strength–it doesn't stretch or bend well, so it cracks easily. Steel reinforcing bars, rebar, or wire mesh are used to add tensile strength. Rebar comes in 20-foot lengths; 1/2-inch bar is adequate for most home projects. If your design has curves, you can bend rebar by hand. Have a helper stand on a board placed over the bar. Slip a pipe over one end of the bar to where you want the bend, then lift up on the pipe. There's also a tool designed to cut and bend rebar. Rent one if you have a lot of rebar to install.
