Can I pour a 2 inch concrete slab? If done properly, new concrete can often be poured right over an existing slab. For this to be feasible, the contractor needs to pour at least 2 inches thick, use smaller aggregate, and incorporate reinforcement such as welded wire mesh or fiber mixed into the concrete.

Do you need rebar for 4 inch slab?
No, you do not need rebar for a 4-inch slab of concrete on grade. A 4-inch-thick slab cast on the ground and in permanent contact with it will float and rebar is not required. Rebar is recommended on concrete measuring 5 – 6 inches thick.
Is rebar better than wire mesh?
Considering the support constraint, rebar is undoubtedly stronger than wire mesh. Several constructors consider rebar for domestic jobs. For thicker driveways and locations that involve greater traffic, rebar is always a good option to consider.
Can you pour concrete directly on dirt?
Long story short, yes you can pour concrete over dirt.
Can I pour a 3 inch concrete slab?
Here, pouring a concrete slab 4 inches in thickness is fine. While you may choose to reinforce it with rebar, wire mesh should be sufficient. A 3- to 4-inch slab will work for the floor of a storage or tool shed, workshop, garden shed, or playhouse.
Do you need gravel under concrete?
Whether you pour concrete for a walkway or patio, a strong gravel base is required to prevent the concrete from cracking and shifting. Gravel is especially important in clay soil because it doesn’t drain well, which results in water pooling under the concrete slab and slowly eroding the soil as it finally drains.

Is quikrete as strong as regular concrete?
Quikrete fast setting concrete is just as strong as regular concrete. Concrete gets its strength from a chemical reaction that occurs over time during curing. After it’s had time to cure, which usually take 28 days to complete, Quikrete can reach strengths up to 5000 psi.
What is the strongest concrete mix ratio?
A strong concrete mix would be something like 1:3:5 (Cement, Sand, Coarse Gravel). In this case, both the sand and gravel are the aggregate.
Is it cheaper to mix your own concrete?
One of the least expensive ways to get concrete is to mix your own. You can buy bags of the mix from a home improvement store. Typically, you only have to add water for it to be ready to pour. Otherwise, you risk getting a weaker concrete once it cures, which could lead to cracks or crumbles within a couple of years.
Should you put plastic under concrete?
A concrete vapor barrier is any material that prevents moisture from entering a concrete slab. Vapor barriers are used because while fresh concrete is poured wet, it’s not supposed to stay that way. It needs to dry and then stay dry to avoid flooring problems. This is why a vapor barrier under concrete is essential.
Do you need rebar for 6 inch slab?
Rebar is recommended for concrete that measures 5-6 inches in depth. The type of and intended use of concrete impacts the need for rebar reinforcement. Rebar must be placed at the center of or slightly above the center of the concrete slab—hence why it should be a certain thickness for best results.
Do you need wire mesh for 4 inch slab?
No, they do not. Larger projects or slabs may need steel reinforcement to provide support or extra strength. Wired mesh can also help resist cracking. However, not every piece of concrete necessarily requires that extra boost.
Should I put wire mesh in concrete slab?
YES When long joint spacing is required or when joints are unacceptable in floor use. Although short joint spacings alleviate the need for reinforcement, wire mesh will allow for increased distance between joints if correctly placed in the upper portion of the slab, at least two inches below the surface.
Can you have too much rebar in concrete?
Rebar or reinforcement is expensive. Using more than recommended will be uneconomical. One more disadvantage of providing excess rebar is that the placement of concrete will become difficult. The concrete should be placed uniformly in the framework which would be affected by the presence of excess rebar.
