5 Things to Know Before Buying concrete slab mesh

In almost any modern construction project, a certain amount of concrete is necessary to get the job done. It's firm, sturdy, and reliable when you know how to use it. Sometimes, the bigger the construction project, the stronger you need your concrete to be. That's why it is important to understand steel reinforcement mesh and its application in strengthening concrete.

What is it? How do you know if you need it? Do all concrete construction projects need reinforcing mesh? Here's what you need to know.

Rebar and Reinforcing Mesh options

When it comes to reinforcing concrete, there are two main options. One option is the rebar, or a reinforcing bar, which is a steel rod that comes in different thicknesses. These are usually ribbed for better grip. Rebars typically encompass the edges of the slabs.

Wired mesh is often paired with rebars, but not always. The steel mesh is made up of wires melded together into a flat sheet. The wires form a square, grid-like pattern. Like the rebars, mesh comes in varying sizes and thicknesses. The most common size is 1/8' thick (4 mm) and 6' long by 6' wide (150 mm x 150 mm).

Neither rebar nor mesh rust inside the concrete like one might suspect. The curing of concrete seals it off from oxygen, which is what causes the rusting of steel. That's why thicker slabs of concrete are better suited to steel reinforcement.

Do All Concrete Projects Need Reinforcement?

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.

When you're working on a major project, it's important to carefully look over plans and building requirements. Some locations require reinforcement no matter the size or scale of the concrete. This is especially true of certain public buildings.

The main slabs that require the steel reinforcing mesh will be those that expect a heavy workload. Anything from a lot of foot traffic, walls, or other foundational pieces will need that extra strength.

How Do You Know If You Need It?

If you're working on something residential like a pathway or a shed floor, you likely don't need the reinforcement. Even some driveways don't need the steel mesh, but most recommend it since vehicles weigh quite a lot.

Something like a carport or garage floor may not require a permit. They should, however, have reinforcement. They take a lot of weight and traffic, so they need the support.

Even if your project is small, take note of the ground underneath. For softer or spongy ground, the slabs on top could benefit from some extra reinforcement!

Conclusion

If your permit or building ordinances require steel reinforcement, mesh wire is a great choice. If you're working on residential projects or your own home, the need for support varies. Take note of the project, the ground underneath, and the purpose of the concrete. All of these factors will help you decide if and how much reinforcement you need.

Welded wire mesh was once the go-to material for forming concrete slabs and reinforcements, but some builders have recently opted for the fiber variety. Though developers may cut costs by opting for synthetic mesh, there are a few things to consider before making the switch.

Read on to learn about the potential drawbacks of fiber cloth and why traditional welded steel mesh may be the best choice.

What to Consider Before Using Fiber Mesh

One of the main reasons mesh is used for concrete slabs is to prevent surface cracking. Though fiber cuts down on the number of breaks, it doesn't eliminate them entirely. Not only that, but when cracks appear, fiber mesh often lacks the strength to stop them from spreading.

So, while synthetic mesh may be more affordable upfront, builders could end up paying more for repairs down the road. Homebuyers and commercial real estate investors are often on the lookout for flaws, and cracks on a new build can stick out like a sore thumb.

Another thing to consider is that fiber mesh doesn't do as good a job preventing differential settlement. Seeing as a level foundation is vital, and fixing it isn't always a simple process, this is a major concern.

Welded Wire Mesh for Concrete Reinforcing

Created by heating intersecting metal wires with an electric current, welded wire mesh boasts impressive rigidity. It's also resistant to abrasion, rust, corrosion, and extreme temperatures.

These characteristics make welded stainless steel cloth ideal for concrete reinforcing, a process that relies on exceptional strength and inflexibility. The durable alloy also helps ensure foundational evenness.

Do Concrete Slabs Really Need Welded Wire Mesh?

There's no one-size-fits-all way to construct houses and buildings. The choice of materials often depends on various factors, like availability, budgeting, and whether substantial settling is common in the area.

All that said, welded reinforcement concrete mesh remains the gold standard for construction. The heavy-duty product is incredibly sturdy, resilient, long-lasting, and versatile.

Minor cracks and slight foundational settling are often to be expected, even with new builds. Still, too many imperfections can signify poor workmanship and lead to prospective buyers feeling dubious about the structural integrity.

Ensuring Crack-Free Concrete

Choosing welded metal mesh over fiber is the best defense against cracks in concrete slabs. However, as with all structural projects, the material can't do its job if it's not installed correctly. Proper installation ensures the maximum level of strength is applied, which keeps breaks at a minimum.
