Concrete Reinforcement Question!



Opinions vary, and this is just my opinion based on my "good luck" on the 4 previous buildings I have had at 3 previous homes.

In regard to your Wire Mesh questions: stay away from the rolls, buy Wire Mesh Mats.

There's a lot of engineering that goes into concrete welded wire mesh. Here's a link fall that engineering: Standard Practice for Structural Welded Wire Reinforcement.. lot's of good data here:

The concrete wire mesh at Home Depot and your local lumber yard is typically 10 gauge, the thinnest wire mesh mat available.

8' x 20' concrete wire mesh mats are available from companies like HD WhiteCap (they have stores in Washington) in various gauges, such as 10, 6 and 4 gauge.

Here are some more links for you:

To support the wire mesh mats use concrete dobies. These are square pieces of concrete with a wire in them that allows you to tie it to the mesh.

Here's a link to various dobies:

And this is the size I used. I picked them up at the local HD Whitecap for 0.28 cents a piece:

I'd caution you on the use of bricks. Ideally you want a product that the concrete will adhere to, and that wouldn't degrade over time and leave a void. Nothing is better than concrete for this application.

If you use 6 gauge concrete wire mesh, on concrete dobies spaced on 24" centers, it is a stiff enough assembly such that it stays where you want it.

Hope this helps. Good luck with your project.

As a side note:

I would recommend against the use cattle panels that Evilunclegrimace recommended above. Most of these panels have a non-uniform panel layout which creates non-uniform stresses in the concrete. Concrete wire mesh is made from high tensile strength steel specifically manufactured, welded and tested for it's intended purpose. Cattle panels are made for, well, cattle.&#;

Model A Fan I think your choice of wire mesh is a good one for a properly designed residential slab that doesn't see high loads and that has a properly compacted sub-grade. The wire mesh 6" square pattern is better than re-bar spacing of 18" or 24".Opinions vary, and this is just my opinion based on my "good luck" on the 4 previous buildings I have had at 3 previous homes.In regard to your Wire Mesh questions: stay away from the rolls, buy Wire Mesh Mats.There's a lot of engineering that goes into concrete welded wire mesh.

When it comes to constructing durable and long-lasting concrete structures, proper reinforcement is essential. One crucial component in this process is wire mesh. Wire mesh plays a vital role in reinforcing concrete, providing strength, stability, and durability to various construction projects. In this comprehensive guide, we&#;ll explore everything you need to know about choosing the right wire mesh for concrete applications, with a focus on the expertise of YKM International LLC.

Understanding the Importance of Wire Mesh in Concrete

Before delving into the specifics of wire mesh types and considerations, it&#;s essential to understand why wire mesh is crucial in concrete construction. Wire mesh serves as a reinforcement material, helping to distribute the load across the concrete surface and minimize cracking. By adding wire mesh to concrete, it enhances its tensile strength, prevents cracking, and improves overall structural integrity. Additionally, wire mesh aids in controlling shrinkage cracks and increases the lifespan of concrete structures.

Types of Wire Mesh Available for Concrete Applications

Welded Wire Mesh

Welded wire mesh, also known as welded wire fabric (WWF), consists of a series of welded steel wires arranged in a grid pattern. This type of wire mesh is commonly used in concrete applications due to its strength, durability, and ease of installation. Welded wire mesh comes in various wire thicknesses and mesh sizes, making it suitable for a wide range of concrete projects.

Expanded Metal Mesh

Expanded metal mesh is another popular choice for reinforcing concrete. It is made by cutting and stretching a single sheet of metal, creating a pattern of diamond-shaped openings.

Expanded metal mesh offers excellent strength and rigidity, making it suitable for heavy-duty applications such as industrial flooring, bridge decks, and highway pavements.

Proficient expanded mesh manufacturers can produce stainless steel, mild steel and galvanized iron expanded mesh.

Rebar

Rebar, short for reinforcing bar, is a steel bar or mesh of steel wires used as a tension device in reinforced concrete and reinforced masonry structures. It strengthens and holds the concrete in compression, enhancing its load-bearing capacity and resistance to cracking. Rebar comes in various sizes and shapes, including round, square, and deformed bars, to suit different construction needs.

BRC Mesh

BRC mesh, or British Reinforced Concrete mesh, is a type of welded wire mesh commonly used in concrete construction. It consists of high-strength steel wires welded together to form a grid pattern. BRC mesh offers excellent reinforcement and crack control, making it suitable for various concrete applications, including slabs, walls, and foundations.

Factors to Consider When Choosing Wire Mesh for Concrete

Selecting the right wire mesh for your concrete project involves considering several factors to ensure optimal performance and durability.

Wire Thickness

The thickness of the wire used in the mesh is a crucial consideration. Thicker wires provide greater strength and load-bearing capacity, making them suitable for heavy-duty applications. However, thinner wires may be sufficient for lighter loads or smaller-scale projects.

Mesh Size

The size of the mesh openings, or the distance between wires, is another important factor. Smaller mesh sizes offer better reinforcement and crack control, especially for thin concrete sections or areas prone to cracking. Larger mesh sizes are suitable for applications where reduced material usage and cost-effectiveness are priorities.

Material Composition

The material composition of the wire mesh affects its durability, corrosion resistance, and overall performance. Common materials used in wire mesh include carbon steel, stainless steel, and galvanized steel. Stainless steel mesh offers excellent corrosion resistance and longevity, making it ideal for outdoor or high-moisture environments.

Surface Treatment

Surface treatment options such as galvanization or epoxy coating can enhance the durability and corrosion resistance of wire mesh. Galvanized wire mesh is coated with a layer of zinc to protect against rust and corrosion, making it suitable for outdoor applications exposed to moisture and harsh weather conditions. Epoxy-coated wire mesh provides added protection against corrosion and chemical exposure, extending the lifespan of the mesh in corrosive environments.

Installation Guidelines for Wire Mesh in Concrete

Proper installation of wire mesh is essential to ensure its effectiveness in reinforcing concrete structures. Here are some guidelines to follow during the installation process:

Proper Placement

Wire mesh should be positioned in the middle of the concrete slab or wall to provide uniform reinforcement. It should be placed at the correct depth to ensure adequate coverage and support throughout the concrete structure.

Securing the Mesh

Wire mesh should be securely anchored to the surrounding concrete or supports to prevent displacement during the pouring and curing process. Use appropriate fasteners, such as tie wire or chairs, to secure the mesh in place and maintain proper alignment.

Overlapping and Splicing

When using multiple sheets of wire mesh, ensure proper overlapping and splicing to create a continuous reinforcement layer. Overlapping mesh sheets by at least six inches and securely fastening them together ensures a strong and seamless reinforcement grid.

Benefits of Using Quality Wire Mesh for Concrete

Utilizing high-quality wire mesh in concrete construction offers numerous benefits, including:

Reinforcement

Wire mesh reinforces concrete by distributing loads and minimizing cracking, enhancing the structural integrity and durability of concrete structures.

Crack Control

By providing additional tensile strength and support, wire mesh helps control cracking in concrete, especially in areas prone to shrinkage and thermal expansion.

Increased Durability

The use of quality wire mesh extends the lifespan of concrete structures by reducing the risk of cracking, spalling, and deterioration, even in challenging environments.

Conclusion

Choosing the right wire mesh for concrete applications is essential for ensuring structural integrity, durability, and long-term performance. By considering factors such as wire thickness, mesh size, material composition, and installation guidelines, you can select the optimal wire mesh solution for your project&#;s needs.
