💡 Composite rebar is a reliable, durable material that significantly reduces construction budgets. However, if proper installation procedures are violated, even the highest quality material will not perform as intended inside concrete. In this article, we cover the top 5 errors when installing fiberglass rebar and explain how to get it right.
1. Using Welding Instead of Tying
❌ Mistake: Attempting to join composite rebar bars together using arc welding.
✔ How to do it right: Composite rebar consists of glass fibers bound by polymer resin — welding destroys the material. Rebar cages should be tied using plastic cable ties (zip ties) or traditional binding wire. For details, refer to our technical documentation.
2. Bending Rebar Bars On-Site
❌ Mistake: Heating or forcibly bending a fiberglass bar at a 90° angle with a manual rebar bender.
✔ How to do it right: Fiberglass rebar is elastic and will snap if subjected to sharp manual bending. To reinforce foundation corners, use factory-preformed L-shaped or U-shaped elements, or smooth curved overlaps.
3. Laying Rebar Directly on Soil or Sand Cushions
❌ Mistake: Placing the rebar cage or mesh directly on the ground prior to pouring concrete.
✔ How to do it right: Rebar must be fully encased inside concrete with a minimum protective concrete cover of 20–30 mm on all sides. Use plastic rebar chairs or spacers to elevate the cage so it properly absorbs tensile loads.
4. Insufficient Overlap Length
❌ Mistake: Joining rebar ends butt-to-butt or with a minimal overlap of 5–10 cm.
✔ How to do it right: To ensure proper load transfer between bars, the overlap length must be at least 30–40 times the rebar diameter (e.g., for 8 mm rebar, the overlap should be at least 25–30 cm).
5. Ignoring Equivalent Replacement Rules
❌ Mistake: Replacing steel rebar with fiberglass rebar on a 1-to-1 diameter basis without considering structural requirements.
✔ How to do it right: Composite rebar is stronger in tension than steel, allowing equivalent replacement with a smaller diameter (e.g., 12 mm steel replaced with 8–10 mm fiberglass). Check the conversion table in our Templet technical specifications.
Following these basic installation guidelines ensures a durable, crack-free foundation, driveway, or slab for decades. Select required diameters and place your order in our product catalog.
