When designing concrete structures reinforced with FRP bars, engineers must consider several critical factors. First, the bond between the FRP bars and concrete is crucial for load transfer. The surface texture of FRP bars is designed to enhance bonding, and the concrete mix must be tailored to optimize this bond. Proper preparation of the concrete interface is essential to prevent slippage under tensile loading.

2. Corrosion Resistance FRP materials are inherently resistant to corrosion, which is a critical factor in drainage applications. Traditional metal channels can suffer from rust and degradation over time, particularly in environments rich in chemicals or moisture. In contrast, FRP drain channels maintain their integrity and performance, reducing maintenance requirements and lifecycle costs.
