FRP++ Bonding & Protection

The Problem: Weak FRP Bonding & Corrosion Risk in Reinforced Concrete

Fiber Reinforced Polymer (FRP) systems are widely used to strengthen concrete structures. However, poor concrete tensile strength, high porosity, and embedded rebar corrosion can compromise FRP bonding, leading to premature failure and reduced reinforcement efficiency.

Without proper surface preparation, FRP adhesion is limited by the concrete’s weakest layer, increasing the risk of cohesive failure under high-stress conditions.

The Solution: Surtreat’s FRP++ System with SurCoPrimer

Surtreat’s FRP++ system is designed to enhance FRP bonding, improve tensile strength, and prevent corrosion:

  • SurCoPrimer: Increases concrete surface tensile strength by an average of 200 PSI.
  • Corrosion Inhibition: Forms a protective layer around rebar, reducing corrosion rates by up to 80%.
  • Improved Bond Integrity: Creates a denser concrete matrix for better FRP adhesion.
  • Reduced Porosity: Minimizes moisture ingress, preventing future deterioration.

Application Process: How to Strengthen FRP-Concrete Bonding

Step 1: Surface Preparation
- Remove contaminants and weak surface layers using mechanical cleaning.
- Ensure the concrete is clean and dry before primer application.

Step 2: Apply SurCoPrimer
- Apply SurCoPrimer at 100 ft² per gallon using a roller, brush, or spray.
- Allow full penetration, then reapply if necessary for optimal coverage.
- Lightly spray water after drying to aid deeper penetration.

Step 3: Install FRP System
- Follow FRP manufacturer’s specifications for adhesive and curing.
- Apply FRP fabric or panels, ensuring proper alignment and adhesion.
- Allow curing per recommended guidelines for maximum bond strength.

Results: Why Surtreat’s FRP++ System Works

Increased Concrete Strength – Surface tensile strength improved by an average of 200 PSI.
Enhanced Corrosion Protection – Reduces chloride-induced corrosion, extending rebar lifespan.
Stronger FRP Bonding – Denser concrete matrix improves adhesion and load-bearing capacity.
Reduced Moisture Ingress – Minimizes porosity to prevent water damage and premature FRP failure.
Long-Term Durability – Ensures FRP reinforcement remains effective for decades.
