Understanding Spalling & Delamination

Steel rebar corrodes over time, especially in the presence of moisture and salts. As it rusts, it expands — cracking the surrounding concrete. This leads to **spalling (surface flaking)** and **delamination (layer separation)**, weakening the structure and demanding costly repairs.

GFRP Rebar Prevents the Problem Entirely

GFRP rebar does not rust, swell, or chemically react with concrete. This prevents internal pressure build-up, eliminating the root cause of spalling and delamination — even in high-moisture and chloride-rich environments.

• No rust = no expansion
• Maintains concrete surface integrity for decades
• Reduces crack propagation and surface failure

Long-Term Surface Stability

With GFRP rebar, your structures will retain their appearance, function, and integrity longer — without unsightly or hazardous surface damage:

• No costly patching or resurfacing needed
• Maintains aesthetic and load-bearing performance
• Ideal for visible concrete applications and high-traffic zones

Applications That Demand Surface Durability

Use GFRP rebar in structures where spalling and surface degradation can’t be tolerated:

• Parking garages & decks
• Bridge parapets & barriers
• Architectural and exposed concrete
• Stadiums, walkways & rooftop slabs
