Description

The SikaWrap Hex Structural Strengthening System is a textile based structural strengthening system available in two options;

• SikaWrap Hex-100G (Glass fiber) plus Sikadur Hex-300, plus the option of adding Sikacrete-213 F (for fire protection); or
• SikaWrap Hex-103C (Carbon Fiber) plus Sikadur Hex-300 plus the option of adding Sikacrete-213 F (for fire protection).
