Like everything, fiber mesh has pros and cons about using it. You have to make sure it’s suitable for your needs before you endeavor to use it for your project. Here are some of the advantages of choosing fiber mesh concrete.
Pros Of Fiber Mesh Concrete
Holds Concrete Together Longer
Cracking can occur because of changes in temperatures. It can also arise from density changes from setting the concrete. Fiber mesh does not keep cracks from forming. Instead, the fiber mesh will hold the concrete together and prevent it from falling apart.
When concrete is going through the curing process, the water inside the concrete evaporates. The method of water evaporation can cause cracks in the concrete. Fibers such as polypropylene reduce cracking by protecting the concrete from stresses. And steel fibers reduce cracking by intersecting cracks and stopping their growth.
Helps With Bleed Water
There are only a few ingredients that make cement. These ingredients include the following:
- Cement
- Water
- Aggregates such as:
- Rock
- Sand
- Gravel
Water is the lightest of all these ingredients. And not all of it gets absorbed by the sand and cement. For these reasons, this will cause excess water to rise to the surface. The water will then pool on the surface of the concrete. This is known as bleed water.
Fiber mesh concrete bleeds more evenly than plain concrete. As a result, you will not experience a puddling effect. Fiber mesh concrete will look more like a wet sheen.
Gives The Concrete Surface A Higher Impact Resistance
Fiber mesh concrete reduces the total crack void structure. This will give the concrete a greater shock-absorbing quality. The concrete will change from a brittle material to a more ductile material.
Takes Less Time Than Wire Mesh To Use
Wire mesh requires careful measuring in order to fit the side of the pour. It also must hold up to a certain level during the pouring process. Alternatively, fiber mesh can be added directly to the concrete mix. This removes the extra step of measuring before pouring.
It Is A Better Option For Certain Projects
Depending on your project, you can’t use reinforcements like rebar or wire mesh. Instead, only fiber mesh concrete will work. If you need to make a thin structure, like a kitchen countertop, rebar won’t work. Instead, you will need to use fiber mesh concrete. If you need to lay a thin layer of pavement, rebar won’t work. Again, you will need to use fiber mesh concrete.
Helps Prevent Fire Damage
Spalling is when the surface of the concrete is heated, forms steam, and then the surface explodes. When fiber mesh concrete is exposed to heat, the fibers inside the concrete will melt. This gives the water inside the concrete a chance to expand and move away from the heat, preventing spalling.
Freeze-Thaw Resistance Is Improved
Water expands when it is frozen. And water inside concrete is susceptible to freezing. Freezing creates pressure in the concrete’s pores. And if the pressure exceeds the tensile strength of the concrete, the concrete can rupture.
After exposure to several freeze-thaw cycles, things like cracking, scaling, and crumbling can occur. When fibers are added to concrete, its freeze-thaw resistance will improve. Polypropylene and nylon fibers are generally used to increase freeze-thaw resistance.
Fiber Mesh Is More Cost-Effective
To determine the cost-effectiveness of fiber mesh, there are several things to consider:
- Material cost–actual cost of the product
- Handling Cost–cost to handle the material. Includes off-loading, storing, and moving.
- Cost to Place–Amount it costs to put the material in place
- Permanent Support Costs
- Concrete Pump Costs

Cons Of Fiber Mesh Concrete
As fiber mesh concrete has advantages, it also has disadvantages. Sometimes, these cons can make or break the decision on using this product. Therefore, we felt it was vital for you to know the downside of using fiber mesh before you decided for sure if it’s the ideal product for your project.
Creates A Hairy Finish
When fiber mesh concrete is laid, some fibers will protrude from the surface. The protrusion of fibers will give the concrete a hairy look. If the appeal isn’t a worry to you, then this isn’t a big deal.
Potential Injury Caused By Glass Or Steel Fibers
Both glass and steel fibers are sharp. If glass or steel fibers are used in the concrete mixture, it may cause injury. Common injuries would include cuts, which
could be severe.
Uneven Distribution Of Fibers Throughout The Concrete
When fibers are added to the concrete mixture, it is impossible to tell where in the mix the fibers will end up. Some portions of the concrete will end up having more fibers than other parts. This will cause the concrete to have different properties in higher fiber areas versus lower fiber areas.
Corrosion Of Steel Fibers
If steel fibers are used in the fiber mesh mix, the steel fibers will corrode over time. The corrosion will adversely impact the performance of the steel fibers and potentially affect the performance of the cement.
