What is What Wire Mesh to Use in Concrete and Why Do We Use Them?

Wire mesh reinforced concrete is used in a variety of construction applications to enhance the strength and durability of structures. Here are some common situations when it is beneficial to use wire mesh and how it works.

Where can wire mesh reinforce a structure?

There are many structures that might require the use of wire mesh. These are some examples.

1. Slabs and floors: It is commonly used in concrete slabs and floors to improve their load-bearing capacity and prevent cracking.
2. Foundations: Wire mesh reinforcement is used in foundation slabs and footings to provide additional support and help prevent shifting or settling.
3. Concrete walls: In both residential and commercial construction, wire mesh can be used within walls to add strength and prevent cracking.
4. Beams and columns: Structural beams and columns often incorporate wire mesh or rebar to ensure they can handle the loads placed on them.
5. Overlays and patching: When applying a new layer of concrete over an existing surface or repairing damaged areas, wire mesh can help ensure a strong bond and durability.

How does wire mesh work?

Wire mesh enhances the strength and durability of concrete through a process of reinforcement that addresses the weaknesses of concrete. Here’s how it works:

1. Load distribution: Wire mesh, usually made of steel, is embedded within the concrete. This mesh helps distribute loads and stresses more evenly across the concrete surface. By spreading the forces over a larger area, the mesh reduces localized stress that could lead to cracks.
2. Crack prevention: Concrete is strong in compression but weak in tension. When subjected to tensile forces, concrete can crack. The steel wire mesh adds tensile strength, helping to control and limit the size of cracks. The mesh holds the concrete together and helps maintain the structural integrity even if cracks form.
3. Increased bonding: The wire mesh is embedded within the concrete, so it becomes an integral part of the structure. This helps to create a strong bond between the concrete and the mesh, ensuring that the mesh effectively contributes to the structural strength.
4. Improved structural integrity: By reinforcing concrete with wire mesh, you reduce the risk of structural failure. The mesh helps resist bending, shear forces, and other stresses that concrete alone might not handle well.
5. Durability: The addition of wire mesh improves the overall durability of concrete structures, making them more resistant to environmental factors such as temperature changes, moisture, and soil movement.

How can Mid-Continent Steel and Wire benefit your project?

Our Welded Wire Reinforcement Mesh is designed for reinforcing concrete and can be produced with W-Smooth/Plain wire or with D-Deformed wire, and with wire ranging in size from 1.4 – 6. Can be used in many cases in combination and/or as a substitute to rebar.

Concrete can be reinforced with two different types of mesh: wire and fiber. These two materials are very different from one another, with each type having advantages and disadvantages that should be recognized. In this article, we'll go over those differences to ensure that you're able to pick the right type of mesh for your project, no matter what you're building or rebuilding.

What Is Wire Mesh?

Wire mesh reinforced concrete is a wire mesh that's positioned in the middle of concrete as it is poured. Once the wire mesh is in position inside the concrete, the concrete is left to cure. The purpose of the mesh inside the concrete is to prevent the concrete from cracking, and to improve the concrete's flexural strength. Wire mesh is kept in place with spacers and wire ties.

To install wire mesh in concrete, the wire mesh is laid down first, and concrete is poured on top of the mesh. Once some concrete is poured on top of the mesh, the mesh is lifted to be positioned partway up the thickness of the concrete rebar. Finally, more concrete is poured over the mesh, and the concrete is allowed to cure with mesh in the middle.

When to Use Wire Mesh in Concrete

Wire mesh is suitable for horizontal slabs. Wire mesh comes in rolls that is cut to size and laid down in the area where the concrete is poured. The concrete is poured on the mesh, and then mesh is lifted slightly to be positioned in the middle of the concrete. Wire mesh is easily tangled and needs to be detangled before it can be laid down for the pour.

Advantages of Wire Mesh

There are many advantages and benefits of wire mesh, including:

• Wire mesh bars don't shift their position when the concrete is poured on top, because they're welded together in a grid. This ensures the mesh is doing its job.
• Wire mesh bars come in rolls that are easily transported onto the jobsite.
• Because mesh bars don't shift their position when concrete is poured on top, installation is relatively simple.

Disadvantages of Wire Mesh

Wire mesh can take up more space on the jobsite compared to fabric mesh, which is easily transported in bags. In addition, rolls of mesh can become tangled with each other, which can slow progress. Wire mesh can also deteriorate over time.

Cost of Wire Mesh

Wire mesh costs an average of $1.04 and $1.21 per square foot. This does not include any labor costs or time spent on installation.

What is Fiber Mesh?

Fiber mesh is a mesh made up of a variety of materials including glass fibers, natural fibers, synthetic fibers and steel fibers. Fiber mesh concrete can be used in patios, sidewalks, pathways and driveways. Fiber mesh helps concrete retain its toughness and improve its impact resistance.

Unlike the wire mesh, which is laid down in a single layer throughout the concrete, fiber mesh is mixed evenly into wet concrete before it's poured. There are two types of fiber mesh that help protect concrete: microfiber and macrofiber. Microfiber is a very thin mesh that helps prevent the concrete from cracking while it's still wet, and macrofiber helps keep cracks in dried concrete to a small, manageable size. Because wire mesh is distributed evenly throughout the concrete, it provides support throughout the concrete structure.

When to Use Fiber Mesh in Concrete

Fiber mesh is appropriate for flooring applications and delicate concrete forms. Fiber mesh is also appropriate for pillars, beams, and bridges, but only when paired with steel reinforcement.

Fiber mesh comes in water-soluble bags in pre-determined weights. The bags are added to the back of the mix truck during the concrete's final mixing stages. The fibers need to be well mixed in order to be properly distributed throughout the concrete, so the truck spins the concrete on high speed. Fibers that are not given adequate time to mix with the concrete will form clumps.

When the concrete is ready to be poured, it's poured in the same manner that traditional concrete is poured. Pouring mesh fiber concrete is quick and efficient. This process requires less labor and fewer people, compared to wire mesh.

Advantages of Fiber Mesh

There are many advantages and benefits of fiber mesh, including:

• Fiber mesh is easy to work with. It does not become tangled up like wire mesh, and mixing it with a load of concrete is easy.
• Synthetic fibers in fiber mesh is corrosion resistant.
• Fiber mesh is generally cheaper than wire mesh.

Disadvantages of Fiber Mesh

While fiber mesh is overall easier to use than wire mesh, there are some disadvantages to using this product, including:

• Clumping. Synthetic fibers are prone to clumping together. If enough time is spent mixing the fibers in the wet concrete, it will mix evenly.
• Time consuming. It's important to allow fibers enough time to mix with the wet concrete before laying it down.
• Fibers can appear in the surface of the concrete. The synthetic fibers can poke up through the surface of the concrete.

Cost of Fiber Mesh

Fiber mesh costs between $0.13 and $0.38 per square foot, depending on the type being installed.

Fiber Mesh vs Wire Mesh: Which to Choose for Your Project?

Fiber and wire mesh can often be used interchangeably in flooring applications. Fiber mesh is more appropriate for delicate concrete forms and thin layers of concrete, versus wire mesh, which is generally used for thicker concrete forms.
