Concrete Reinforcement in Slabs
Commonly called "rebar," these 1/2-inch-diameter steel rods are embedded in the center of the slab to create a grid that extends lengthwise and crosswise to help the concrete better resist pulling and bending forces. Ridges in the surface of the rebar allow the concrete to adhere to it and create one solid structure.
Choosing the Right Tools for Concrete Demolition
Break up the slab into small chunks, cut the wires or rebar and separate the concrete as you work toward the middle. If you're dealing with wires, use bolt or wire cutters, and if rebar is present, use a reciprocating saw. 4. Think About Your Disposal Strategy. Once you break the concrete, you can't place it into a regular garbage bin.
How Do You Cut Through Reinforced Steel Concrete?
Some concrete is made with 'rebar', or iron rods that are set into the structure before the concrete is poured. This is common for foundations, for example. The idea is that the rebar will help to hold the concrete in place, stopping it from shifting or cracking. Concrete with rebar is incredibly strong, by design.

Dobie Cement Support Blocks
For best results, rebar is generally located at the center or slightly above the center of a concrete slab. Instead of "placing" or inserting the rebar during a concrete pour, the rebar is prepared at the proper location and height, then the concrete is poured under, around, and over the rebar to embed it in the slab.

Concrete Rebar 101: Why and How Does It Strengthen Concrete?
Concrete rebar helps the concrete to resists breaking and cracking. The rebar gives the concrete additional strength, so it can withstand greater loads without breaking beneath the tension. Additionally, rebar helps distribute the weight evenly throughout the concrete, so if any cracking does occur, it is controlled and does not …
How to Break Concrete | Total Concrete
Cover the concrete slab with plastic sheeting, especially if you're working near windows. 2. Dig under the concrete if possible. 3. Starting from the edges and working your way in, use your chosen tool to break up the concrete. 4. If using a sledgehammer, pry the concrete with a crowbar as you go. 5. Cut any mesh with bolt cutters or an ...
How to Harness the Strength of Rebar in Concrete Projects
The correct placement of rebar in concrete projects is extremely important. If spacing is changed even 1 inch, the concrete can lose as much as 20% of its strength. Brooks Construction has been in the concrete business since 1946. So if you decide you need help, reach out or give us a call at 605-368-5447!
How to Drill Into Concrete Safely
After drilling the hole, continue to wear your safety goggles and grab a can of compressed air. The best air compressors for this step will have a blow gun attachment that makes it easy to direct the air. Point the air compressor at the hole you drilled and blow directly into it, removing any remaining dust and debris.

2. Determine the rebar gauge. The gauge, or diameter, of the rebar is selected based on the purpose and the load-bearing requirements of the structure: For standard residential concrete slabs, #3 (3/8 inch diameter) to #5 (5/8 inch diameter) rebar is typically used. For driveways and patios, #4 (1/2 inch diameter) rebar is a common …
