The core of fiberglass sewer pipe lies in its composite structure, which consists of a strong, flexible glass fiber matrix encased in a tough, waterproof resin. This combination provides the pipe with outstanding strength-to-weight ratio, making it easier to handle and install compared to heavy concrete pipes. Additionally, the corrosion-resistant nature of fiberglass eliminates the common issues associated with metal pipes, such as rust and corrosion, ensuring a longer lifespan for the sewer system.
