Types Of Reinforcement In Concrete
Reinforcing steel has been used for over 150 years in concrete and has undergone improvements throughout that time. Although there are other ways to reinforce concrete, the focus of this article is on steel, and how it is used to improve the tensile strength of pads, slabs, driveways, and walkways. Rebar is used to form the skeletal structure that helps concrete withstand bending and stretching forces to keep it strong.
Rebar is either plain or deformed. The plain profile is smooth and is commonly pushed into concrete before it sets. The deformed profile has ridges to bond with or grip the concrete as it is poured. The two profiles have specific purposes but work similarly to strengthen concrete.
There are different diameters and grades of rebar designed for varying purposes and structures. Prior to a pour, the steel is cut, bent, and tied together to form a wire fabric-like weave, web, or skeleton within the forms. The thicker the rebar and closer the spacing between strands, the greater the strength it brings to the concrete.
Structures that require rebar are commonly inspected prior to the pour to ensure spacing and location are acceptable. Improper spacing or placement by even an inch can weaken the strength by 20%. Along with spacing and placement, the type of rebar is important.
When To Cut Control Joints
Make sure you are cutting joints soon enough. In hot weather, concrete might crack if joints are not cut within 6-12 hours after finishing concrete. In this condition, if you dont want to use a grooving tool to cut joints, there are early-entry dry-cut lightweight saws that can be used almost immediately after finishing. These saws cut 1 to 3 deep, depending on the model.
Install The Forms And Reinforcemenet
The thickness of your patio slab will determine what you use for forming material. Most likely your patio slab will be 4″ thick. That’s quite common for a patio slab.
IF that’s the case, you can use either 2×4’s or 2×6’s to form your concrete patio. The size and shape of your patio will be determined by you and your space or area you have to install the patio.
Setting up forms is fairly simple. Here is more information about forming that will help you.
For reinforcement, you can use wire mesh or rebar. Both are good and will help reinforce the concrete if it does end up cracking.

How Thick Does A Concrete Slab Need To Be For A Shed
You can probably get away with pouring a 7.5 cm thick concrete slab if you are planning on a light shed with nothing much in it. However, if you want to be on the safe side, go for a 10 cm concrete slab.
You first need to make sure your concrete slab is in the right place. Check your council regulations, because your shed cannot be just anywhere. Once you have that information, mark the soil where you want to dig and prepare the formwork for the concreting.
In that way, you will see if you need to make adjustments if the soil is slated or there are any other complications.
Do Concrete Patios Need Rebar
Rebar is a steel bar that is used in concrete construction for reinforcement purposes. Also known as reinforcing steel, rebar is composed of steel wires used as a tension device to strengthen and aid concrete under tension. It provides structural strength to projects and helps control where and the extent of the concrete cracks
Even though its possible to build a concrete patio without rebar, its not recommended. All concrete is subject to cracks, but rebar holds all the cracks together and keeps the slab level and even. Without rebar, the cracks would become quite wide and the concrete would become uneven. This would cause the concrete to be replaced much sooner.
How To Mix And Pour Concrete Patios
A concrete patio can be a great garden addition, whether located immediately outside your doors or laid as an extra feature to an outdoor pool. Here are the steps to mixing and pouring concrete patios.
Step One – Preparing the Ground
Make the concrete patio outline using stakes and string. You will need to make the outline 3 inches larger than the patio will ulitmately be to allow for the forms. The patio should slope slightly away from the house to drain. Take off the area of turf within the outline and dig down 4 inches. Tamp down the earth so it becomes firm. Use vegetation killer on the bare earth to remove any unwanted weeds. Where the patio meets the foundation, lay down the expansion strips.
To build the forms for the patio, pound in small stakes every 3 feet and add 2×2 lumber to create the form. The top of the lumber should be at the same level as the grass. Keep the strings up to help you check the level of the form and remove once the forms are installed. Fill the form to a level of 2 inches with crushed rock for drainage, tamp down and lay wire mesh on top. This will help strengthen the concrete in the patio.
Step Two – Mixing the Concrete
Dont mix too much at one time or youll need to keep adding water, which will thin the concrete. Remove the concrete from the mixer with the shovel to pour into the form.
Step Three – Laying the Concrete
Step Four – Curing the Patio

For larger patios, you may need more room for the added support, especially if you plan to place heavy objects such as patio tables or hot tubs on the patio. Of course, be sure to assess the specific purpose of your patio as it may affect the depth of the area being dug.
Another factor that may play a role in how deep you need to dig to provide the proper support is whether you want your patio suspended or on the ground. If you want your patio on the ground, then you may need to dig to a deeper depth or otherwise make the patio thinner.

How To Lay Out & Excavate A Patio Site
1. Lay out a rough project outline with a rope or hose. Use a carpenterâs square to set perpendicular lines. To create the actual layout, begin by driving wood stakes near each corner of the rough layout. The goal is to arrange the stakes so they are outside the actual project area, but in alignment with the borders of the project. Where possible, use two stakes set back 1 ft. from each corner, so strings intersect to mark each corner . Note: In projects built next to permanent structures, the structure will define one project side.
2. Connect the stakes with masonâs strings. The strings should follow the actual project outlines. To make sure the strings are square, use the 3-4-5 triangle method: measure and mark points 3 ft. out from one corner along one string, and 4 ft. out along the intersecting string at the corner. Measure between the points, and adjust the positions of the strings until the distance between the points is exactly 5 ft. A helper will make this easier.
3. Reset the stakes, if necessary, to conform to the positions of the squared strings. Check all corners with the 3-4-5 method, and adjust until the entire project area is exactly square. This can be a lengthy process with plenty of trial and error, but it is very important to the success of the project, especially if you plan to build on the concrete surface.
8. Lay a subbase for the project . Pour a 5″-thick layer of gravel, and tamp until the gravel is even and compressed to 4″ in depth.
