what are the pro&#;s & con&#;s of re-bar vs. wire mesh for a 350sq. ft. garage slab poured 4&#; thick? are they even necessacary? am also doing a 750 sq. foot great room with stained concrete & radiant floor heating&#;what are my best bet&#;s to prevent the inevetable cracking of the concrete (would like to avoid cutting the slab if possible)? get a different answer from each concrete sub I talk to about these issues&#;would anyone be kind enough to lead me in the right direction? thanks!
Concrete-formed floors, platforms, roadways, and walls need reinforcement to prevent cracking. Wire mesh and Fibermesh® are the most common reinforcement products used to maintain concrete integrity.
This article will cover the primary differences between Fibermesh® and wire mesh and how to choose the best one for your project.
Wire mesh, sometimes called welded steel fabric, is composed of separate rods of heavy-gauge galvanized wire mesh welded together in crisscrossed patterns.The panels are easy to position into concrete forms, and then fresh concrete is poured over them. Wire mesh is less expensive, stronger, and easier to work with than traditional rebar. It&#;s also used to increase the concrete&#;s tensile strength and is essential for any project with a deficient subgrade.
Concrete wire mesh is primarily used to strengthen structures like:
Tunnels
Runways
Roadways
Pavements
Bridge Decks
Square wire mesh for concrete is also used when forming flooring, roofing, and walls in residential, commercial, and industrial structures.
Fibermesh® is a proprietary concrete reinforcement manufactured by Sika®, an international leader in specialty products and chemicals used in the automotive, construction, and industrial markets.
Fibermesh® is manufactured with olefin-free monofilament fibers, plus other fibrous materials (glass, steel, and synthetic fibers), and designed to reduce water loss, enhance structural integrity, improve impact resistance, prevent thawing, and increase tensile strength. Fibermesh® is also designed to meet or exceed ISO standards.
Fibermesh® acts to support aggregates within concrete mixes via a multidimensional network of macro- and microfibers. This product doesn&#;t affect curing, and it doesn&#;t absorb water.
Benefits of Fibermesh® include:
Enhanced Cohesion
Reduced Segregation
Decreased Bleed Water
Enhanced Bleed Uniformity
Elongated Concrete Durability

Hindered Concrete Shrinking & Cracking
Improved Resistance to Abrasion, Shatter, & Impact
Common applications for Sika® Fibermesh® include forming:
Residential Curbs, Decks, & Driveways
Roadways & Sidewalks
Ground Slabs
Bridge Decks
Shotcrete
Toppings
Overlays
Precasts
Stucco
While rebar, wire mesh, and Fibermesh® are all popularly used across numerous construction scenarios, some of their uses overlap.
Using rebar is the slowest of the three reinforcement methods, requiring significantly more time to cut, position, align, and tie or weld together. However, rebar is still a go-to choice for many contractors because, although it&#;s slower and heavier to work with, its strength surpasses wire mesh.
Wire mesh is faster to use but less strong than rebar. It must be rolled out, lined up, and cut to fit the application. However, the diminished diameter of its steel rods makes it weaker than rebar.
Overall, Sika® Fibermesh® is theoretically the strongest option of the three. However, its use in vertical applications hasn&#;t been well-studied yet. Fibermesh® is added to the concrete mix, meaning there&#;s no need to roll it out, cut it, align it, or anything else. It is part of the concrete, making it much less time- and effort-consuming.
It&#;s also important to note that rebar and wire mesh are considerably cheaper than Fibermesh®. So, if your project is budget-sensitive, you may want to invest the extra effort in using rebar or wire mesh. Due to its cost, some people only use Fibermesh® for smaller projects.
