Use wire mesh for driveways that are 4 to 5 inches thick, and rebar for those that are 5 inches or more.
What do you put down before putting concrete?
Before you can put down a concrete slab, you have to lay down a base. A solid base protects the concrete from settling dirt, water runoff, and other natural hazards.
Is gravel necessary under concrete?
You do need gravel under a concrete slab, footing, or patio. Gravel provides a solid foundation for your concrete as it can be compacted. It also improves drainage, preventing water from pooling beneath the concrete.
Do I need rebar in concrete driveway?
This strength is crucial for things like buildings, roads and driveways. Rebar is not necessary for every concrete project. The general rule of thumb is that if you are pouring concrete that is more than 5 inches in depth, you are probably going to want to add in some rebar to help reinforce the entire structure.
Do you need rebar for 4-inch slab?

How much weight will a 4-inch concrete slab hold?
A 4-inch thick concrete can support upto 40 pounds of weight. Weight should not exceed 40 lbs/sq ft on an undetermined 4-inch slab. 80 lb/sq ft in isolated areas is fine, but unless you know what the soil bearing and reinforcing is for that slab, you might be looking at cracking.
Is it OK to pour concrete on dirt?
Long story short, yes you can pour concrete over dirt.
What happens if you don't put gravel under concrete?
Because concrete is a very porous material, it will absorb any moisture that it contacts. This can cause pooling. Without crushed stone, pooling water will settle under it and erode your slab. Adding a layer of crushed stone will add proper drainage, as well as create a barrier between your slab and the ground.

Why do people use concrete for driveways?
Another huge reason concrete is used to build driveways is because of how durable it is. Concrete can withstand any weather condition and pretty much any load . Rockets are launched off of concrete pads because of how strong a material it is.
What is the strength of concrete for driveways?
The main thing to consider when choosing your concrete driveway mix is it’s compressive strength. Compressive strength is the rating of how much compression a material can resist. Compression being the weight of a car or truck. This strength is measured in psi or pounds per square inch. The higher the number the more durable the concrete. In general we pour our driveways at 3500 psi and above.
What is the strength of concrete?
Concrete typically has a very high compressive strength and a much lower tensile strength . Because of the lack of tensile strength, reinforcements like wire mesh, fiber or rebar can be used. Concrete mixes are designed with a certain amount of compressive strength which is rated in terms of pounds per square inch (psi).
How to determine the strength of concrete?
Here’s what you need: 1 A compressive strength of at least 4000 psi. 2 An air content of around 6%. 3 A water-cement ratio below 0.50 to improve concrete durability and strength
Why use a stronger concrete mix?
Because cold areas that see a freeze/thaw cycle typically need stronger concrete to resist expansion and contraction pressure, use a stronger concrete with a higher psi It’s very simple. In areas with cold climates, concrete mix should have a 6 percent air-entrainment value.
How to tell if concrete is dry?
When your concrete is properly mixed it should be a semi-solid that resembles thick oatmeal. A great way to test this is by hand. Simply pick up the concrete with your hand and shape it like a snowball. If the concrete holds its form and you can smooth the edges, then the consistency is right. But if it’s too dry and crumbles apart or you see dust, then you need more water. If the concrete is like soup and can’t be picked up, there’s way too much water and you need to add more dry mix.
Why use steel reinforcement on driveway?
Using steel reinforcement will provide additional structural capacity for your driveway and is especially important if the slab will be exposed to heavy traffic. Reinforcement won't prevent cracks, but it will help hold them together if they do occur.

How to cure concrete that has been acid stained?
Methods of curing include covering the concrete with plastic sheets or wet cu ring blankets, continuous sprinkling, and application of a liquid membrane-forming curing compound. For slabs that are to be acid stained, wet curing is the best approach, since a curing compound would have to be completely removed to allow the acid stain to penetrate. The most common way to cure plain or integrally colored concrete, though, is to use a liquid curing compound. Read more about why curing concrete is important and how it's done.
What is the key to a good subgrade?
Uniformity, in both soil composition and compaction, is the key to a good subgrade-one that will provide adequate support, ensure an even slab thickness, and prevent slab settlement and structural cracking. Soft spots should be removed and replaced with good material, such as gravel or crushed rock.
What is the purpose of a screed on concrete?
Level or strike off the concrete with a screed to achieve a uniform surface.
How long does a concrete driveway last?

How is concrete strengthened?
In many applications, concrete is strengthened by placing steel metal reinforcement wire or rebar within the slab. Other ingredients can also be added during mixing, such as agents that improve strength or slow drying time.
How does finishing work on concrete?
A key part of the finishing process is floating the concrete. After the concrete is poured and smoothed, the finishing crew uses a variety of tools to work the surface of the concrete, drawing the cement and finer particles to the surface through capillary action to create an attractive, smoother surface. The amount of floating determined how smooth the surface will be, and there is considerable craft involved in doing so because excessive floating will weaken the surface and cause it to flake, while too little will leave the slab with a rough, industrial look. This is also the time when a skilled crew can impart decorative finishes and colors to the surface of the slab.
How long does it take for concrete to harden?

Does concrete dry out?
Concrete doesn't dry out ; rather, it undergoes a slow chemical process that hardens and strengthens the material. It is very important that this curing process occurs under the best of circumstances. That begins with the weather. Ideal curing weather is about 70 degrees with a surface that is kept damp but not wet.
How long does a concrete driveway last?
A properly installed concrete driveway should last for many decades-and at least two or three times longer than an asphalt driveway. Because concrete driveways don't need to be replaced or resurfaced as often, fewer raw materials are consumed over the life of the pavement.
What if the driveway cracks?
If your concrete was jointed properly, cracks are unlikely to be a problem. Think of joints as "planned" cracks that allow the concrete to expand and contract, minimizing any chance for random cracking.
What is the cost of a stamped concrete driveway?
Your initial cost to install a stamped concrete driveway can range anywhere from $6 per square foot for basic stamped concrete (using just one pattern and color) to $15 or more per square foot for elaborate multi-pattern designs with special coloring effects (see Stamped Concrete Driveway Cost ).
