Our FRP Stormwater Infiltration Drain Tunnels are engineered for high-performance underground stormwater management. Made from fiber-reinforced polymer (FRP), these drain tunnels provide a durable, non-corrosive alternative to traditional concrete or plastic chambers. The open-bottom arch design allows rainwater to naturally infiltrate into the soil, recharging groundwater while reducing surface runoff. Each tunnel is modular, lightweight, and stackable for transport, making them ideal for large-scale residential, commercial, and infrastructure drainage projects. With a service life of over 50 years in aggressive soil conditions, our FRP tunnels solve flooding and drainage compliance challenges efficiently.
