Underground construction

Advantages of Composite Group fiberglass reinforcement when building underground constructions:


1. Tensile strength is three times higher than steel reinforcement (not less than 1200 Mpa), which is perfect for construction in areas with increased stress

2. High corrosion resistance, resistance to moisture and aggressive fluids significantly increases durability of structures. Not less that 80 years is the expected structure lifespan


3. Fiberglass reinforcement is completely dielectric, which eliminates any interference with radio waves

4. High temperature sustainability. Fiberglass reinforcement withstands a long-term freezes and heats
