Advantages of using basalt reinforcement
- Absolute corrosion resistance
- Non-heat conductive
- Non-heat conductive
Six to eight times
Lighter than steel reinforcement
- Savings on installation and repair works without the use of special lifting mechanisms and equipment
- Savings on transportation of structures and their elements to the place of installation
- Lightweighting of structures
Threefold
Stronger than steel reinforcement
- Has the same coefficient of thermal expansion as concrete
- Savings on repair costs due to the increase in the inter-repair period of structures
