Actually I have about $50,000 in materials and concrete in my shop. None of that was for labor, I built it pretty much by my self. I didn't "over build" it. My neighbor hired out his concrete, 30' by 100" slab with rebar ala chingada to the tune of $25,000. I did my own excavation, set the forms, the re-bar around the perimiter top and bottom, the 8 pillar footings, the 6x6 welded wire mesh pulled tight. My cost for the concrete and a crew to place it was about $9,600. My place is a bit smaller, 40' by 64'. With the roughly 15K difference in cost for the concrete I was able to put in a shitload of insulation and a few nice windows and good quality insulated doors. My floor has a few hairline cracks. I don't care. I can heat mine for about $60.00/month. He can't afford to heat his and it's like an oven in there in the summer. He has no cracks in his floor. So what I'm saying is that sometimes you have to make a compromise. The last shop I built in '94 was done exactly the same way. It has a few small cracks as well. They have not been a problem in either building.

Rebar Vs. Mesh – Reinforcing Concrete Lots & Driveways
Concrete is a sturdy, reliable building material. But just like any other material, it can benefit from reinforcement when used in areas that will see a lot of wear and tear. When it comes to concrete reinforcement, there are two main options: rebar and mesh. Both have their benefits and drawbacks. So, should you use rebar or mesh to reinforce your concrete? Heres what you need to know.
What is Rebar?
A rebar is a steel bar used to reinforce concrete. It is commonly used in driveways, parking lots, and sidewalks. Rebar comes in different sizes and lengths.
What is Wire Mesh?
Wire mesh is also made from steel, but it is a mesh of wires welded together. This material is often found in driveways.
Rebar v Mesh: Which is better for Lots and Driveways?
The answer depends on what type of construction project youre undertaking. But here are some factors that you must consider before deciding which option to go for:
Cost:
Wire mesh is a cheaper steel reinforcing material than rebar. It uses thin steel wires while rebar is a steel bar, and the cost depends on its thickness and size. Rebar may also cost you more in labor. The high cost of rebar may not be justified if its a private driveway or a small area or if you are on a budget. However, it might be cost-effective when used in commercial settings.
Installation:
Wire mesh is easier to install than rebar. So, if your project is time-sensitive, then wire mesh may be the best option. It even requires fewer workers to install as compared to rebar.
Flexural Strength:
While both types are strong, rebar has better bend strength properties than wire mesh and provides better support to the concrete for high or heavy traffic. Rebar is a good choice for projects that will experience a lot of wear and tear, such as industrial lots, underground parking lots, or other commercial parking lots. Wire mesh is a better option for light to medium traffic areas like driveways and sidewalks.

Transport:
If your project site is located far from the supplier or transportation is tricky, wire mesh is a better option as it weighs significantly less than rebar. The lightweight mesh will save on transport costs. Nonetheless, both can withstand the rough conditions during transport.
Thermal Expansion:
Steel and concrete have similar expansion properties when it comes to temperature changes. As a result, wire mesh and rebar will expand and contract at the same rate as concrete. Therefore, concrete bound to these steel reinforcements cracks at a lesser pace than it would without any support.
Structure Type:
Wire mesh is suitable only for horizontal slabs like driveways, patios, and sidewalks. On the other hand, contractors use rebar for horizontal and vertical applications such as walls and columns.
Corrosion Resistance:
Rebar is more corrosion-resistant than wire mesh and can last up to 100 years if properly coated and maintained. Wire mesh will erode much faster; however, various treatments can be applied to protect the wire mesh from rust.
Discuss the suitability of rebar and mesh with your concrete contractor, specific to your project type.
