- For culverts support, natural terrain revetment and other support engineering, own to its highanti - bending and tensile strength.
- For impounding reservoirs, low pressure - water pipes and anti - infiltration of the basements, because of its high performance of anti - crack.
- For the position of high - speed running water, e.g., the spillways and sluice boards of hydraulic and Hydro - Power Engineering, because of its high performance of anti - impact and anti - abrasion.
- Better for the concrete engineering in the condition of being corroded by the seawater, because it is made of synthetic resin with the specialty of steel fiber.
- For bearing the live load, such as the highway bridges, railways and other engineering, because its high performance of fracture toughness, anti-stretch , anti- fatigue etc.
- Concrete Reinforcement , Shotcrete , industrial floors , tunnels and mines (TBM)
