GFRP rebar gives agricultural concrete a longer service life by solving two major problems associated with steel reinforcement: corrosion and conductivity. Unlike steel, fiberglass rebar does not rust in wet, chemical-heavy farm environments, and it does not conduct electricity. That means barns, feed pads, grain bin foundations, and parlor floors can remain in better condition longer while helping create a safer environment for livestock.
For farmers, the biggest benefit is durability. Manure, silage acids, fertilizers, washdowns, and de-icing salts can all accelerate steel corrosion inside concrete. As steel rusts, it expands, causing cracks, spalling, and premature slab failure. GFRP rebar eliminates this failure mechanism, helping concrete perform better in demanding agricultural environments. This can reduce repairs, downtime, and replacement costs over the life of the structure.
Another major advantage is animal safety and comfort. Steel reinforcement can become part of unintended conductive pathways in livestock facilities when electrical faults or grounding issues occur. Because GatorBar is non-conductive, it eliminates one potential path for electrical current through floors and slabs. A Weyerhaeuser article highlighting GatorBar field applications illustrates the value of non-conductive reinforcement in livestock environments.
GFRP rebar also delivers practical jobsite benefits. It is significantly lighter than steel, making it easier to transport, carry, stage, and install. This reduces crew fatigue and can speed installation, especially on remote farm sites or in tight barnyard conditions. Its high tensile strength also helps support crack control in slabs and pads exposed to equipment traffic and daily wear.
These benefits are especially valuable in livestock barn floors, feed slabs, silage pads, grain bin foundations, bunker silos, and manure storage structures. In these applications, non-corrosive reinforcement helps preserve concrete integrity, while improved slab conditions can help reduce surface deterioration that may contribute to slips, hoof issues, or poor footing.

Common Agricultural Applications for GFRP Rebar
Determine Proper Rebar Size and Spacing

Educate the Crew
A short toolbox talk covering cutting, tying, and chairing fiberglass rebar helps eliminate first-day questions. GatorBar is installed using the same placement, tying, and chairing practices as steel reinforcement. Work crews adapt quickly once they experience how lightweight and easy GFRP rebar is to handle (Installation Brochure).
Realize the GatoBar Benefit
From a budgeting standpoint, GatorBar is cost-competitive with steel on a per-foot basis. However, the greatest savings come from reduced labor requirements and a longer service life. Juvi at Mercadal's estimates that using GatorBar has reduced labor costs by approximately 50% on their projects.
The savings become clear when comparing installation labor on a typical agricultural slab. For example, a 2,800-square-foot slab reinforced with #3 rebar in a 6-inch concrete pour can typically be prepared by a two-person crew in approximately 6 to 10 total man-hours. This includes staging and layout, grid placement, tying approximately 1,600 intersections, and installing rebar chairs.
A worker with a $30-per-hour base wage often costs an employer $42 to $45 or more per hour when wages, taxes, insurance, and benefits are included (Thompson Greenspon). At a fully burdened labor rate of approximately $45 per hour, contractors can save roughly $135 to $225 per pour, or more than $20,000 annually for crews placing similar slabs throughout the year.
Beyond the direct labor savings, lighter-weight reinforcement helps reduce employee fatigue, lower the risk of jobsite injuries, and improve worker productivity. Additionally, because GatorBar does not corrode, concrete structures can last longer with fewer repairs and less maintenance. Reduced downtime and extended intervals between major slab replacements are where project owners often realize the greatest return on investment.
Ultimately, GFRP rebar is not an emerging technology—it is a proven reinforcement solution that has been installed in hundreds of millions of feet of concrete across North America, including agricultural applications. That track record, combined with its durability, corrosion resistance, labor-saving installation, and non-conductive properties, makes GatorBar a compelling solution for producers looking to build safer, longer-lasting agricultural infrastructure.
