SikaWrap® Hex-103 C
Carbon fiber fabric for structural strengthening
SikaWrap® Hex-103 C is a high strength, unidirectional carbon fiber fabric pre-saturated to form a carbon fiber reinforced polymer (CFRP) used to strengthen structural concrete elements.
- Used for shear, confinement or flexural strengthening
- Flexible, can be wrapped around complex geometries
- High Strength
- Light Weight
- Non-corrosive
- Alkali Resistant
- Low aesthetic impact
Usage
SikaWrap® Hex-103 C can only be installed by a Sika New Zealand Approved Contractor. Load Increases- Increased live loads

Application
SUBSTRATE PREPARATION
Surface must be clean and sound. It may be dry or damp, but free of standing water and frost. Remove dust, laitance, grease, curing compounds, impregnations, waxes, foreign particles, disintegrated materials and other bond inhibiting materials from the surface. Consult the current product data sheets for Sikadur® Hex-300 for additional information on surface preparation.
Existing uneven surfaces must be filled with an appropriate repair mortar. The adhesive strength of the concrete must be verified after surface preparation by random pull-off test- ing (ASTM D-4541) at the discretion of the engineer. Minimum tensile strength 1.4 MPa with concrete substrate failure.
Preparation Work: Concrete - Blast clean, shotblast or use other approved mechanical means to provide a roughened, open-textured surface. Round all corners to 1/2” radius in certain “contact critical” applications and at the engineers discretion, a thorough cleaning of the substrate using low pressure sand or water blasting may be sufficient.
