Fiber Mesh vs Wire Mesh: Which Should You Use?

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.

Concrete reinforcing mesh, also known as welded wire mesh, is a critical component in construction, particularly in concrete reinforcement. It is used to enhance the structural integrity and durability of concrete elements such as slabs, walls, and pavements. Here are five compelling reasons why concrete reinforcing mesh is essential:

1. Enhanced Structural Integrity

Concrete by itself has high compressive strength but relatively low tensile strength. Reinforcing mesh compensates for this weakness by providing tensile strength to the concrete structure. Here's how it enhances structural integrity:

Load Distribution: Reinforcing mesh helps distribute loads more evenly across the concrete structure, reducing the risk of cracking and failure under stress.

Crack Control: By holding the concrete together, the mesh minimizes the development and propagation of cracks. Even if small cracks develop, the mesh ensures they remain minor and do not compromise the structural integrity.

Improved Durability: Structures reinforced with mesh are more resistant to environmental stresses such as temperature fluctuations, moisture, and chemical exposure, leading to a longer lifespan.

2. Cost Efficiency

Using concrete reinforcing mesh can lead to significant cost savings in construction projects. The reasons include:

Reduced Material Waste: Pre-fabricated mesh sizes reduce the need for cutting and shaping on-site, minimizing material wastage.

Labor Savings: Installation of reinforcing mesh is typically faster and less labor-intensive than traditional rebar placement, leading to reduced labor costs.

Long-Term Savings: The enhanced durability and reduced maintenance requirements of reinforced concrete structures translate into long-term savings on repair and replacement costs.

3. Ease of Installation

Concrete reinforcing mesh is easier and quicker to install compared to other reinforcement methods, such as using individual rebar. Here are some aspects that contribute to the ease of installation:

Pre-Fabrication: Mesh comes in pre-fabricated sheets or rolls, which can be laid out quickly over large areas.

Simplified Placement: The mesh can be easily positioned and adjusted to fit the specific dimensions and contours of the concrete formwork.

Versatility: It can be used in various applications, including slabs, walls, columns, and pavements, reducing the need for multiple reinforcement types and simplifying the construction process.

4. Versatility and Adaptability

Concrete reinforcing mesh is highly versatile and adaptable to a wide range of construction scenarios:

Various Sizes and Configurations: Mesh is available in different sizes, gauges, and configurations to suit specific project requirements, whether it's for light residential use or heavy industrial applications.

Complex Shapes and Curves: The flexibility of the mesh allows it to be bent and shaped to reinforce complex concrete forms, including curves and irregular shapes.

Compatibility: It can be used in conjunction with other reinforcement techniques and materials, providing additional strength and stability where needed.

5. Improved Safety

Reinforcing concrete with mesh enhances the overall safety of the structure during and after construction:

Worker Safety: The use of mesh reduces the need for handling heavy individual rebar, lowering the risk of injury during installation.

Structural Safety: Reinforced concrete is less prone to catastrophic failure, providing a safer environment for occupants and users of the structure.

Resistance to Environmental Factors: The mesh provides additional resistance to environmental factors such as seismic activity, wind loads, and other dynamic forces, ensuring the structure remains safe under various conditions.

Conclusion

Concrete reinforcing mesh is a valuable addition to any construction project due to its ability to enhance structural integrity, provide cost efficiency, simplify installation, offer versatility, and improve overall safety. By incorporating reinforcing mesh into your concrete structures, you can achieve a more robust, durable, and reliable outcome, ensuring long-term performance and stability. Whether for residential, commercial, or industrial applications, concrete reinforcing mesh proves to be an indispensable component in modern construction practices.
