Unidirectional Grade 1 200gsm Carbon Fiber CFRP Wrap for Piers wharfs
Carbon Fiber Reinforced Polymers for Structural Strengthening. These fabrics are applied onto the surface of existing structural members in buildings, bridges and other structures. The result is an externally bonded CFRP (carbon fiber reinforced polymer) reinforcement system engineered to increase the structural performance
Carbon fiber is light weight, easy-to-install, strong (10x stronger than steel) and non-corrosive, which eliminates the need for maintenance. Carbon fiber can also be easily painted over or covered with a finishing product for aesthetic appeal.
Carbon fiber has 3 attributes that engineers, specifiers and contractors look at depending on the project on-hand:
- Weave Orientation (Unidirectional Horizontal, Unidirectional Vertical and Bidirectional)
- Weight (200 GSM, 300 GSM, 400 GSM, 560 GSM, 600 GSM)
- Width (10cm, 30cm, 50cm)
Carbon fibre strengthening can be a cost effective, clean and un-intrusive solution to a common structural problem. It isn’t suitable for every strengthening project and you should always get advice from a specialist contractor about the best method to use.

Advantages of CFRP Fabric
• Easy installation
• Corrosion resistance
• Short construction period
• No maintenance required
• Light weight, no influence to original structure
• Low cost, cost effective compared with other methods
l Adds strength without adding dead load
l Withstands sustained and cyclic load conditions
l Extremely resistant to wide range of environmental conditions
l Easy to conceal
Preparation works
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. 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 testing (ASTM D 4541) at the discretion of the engineer. Minimum tensile strength required is 200 psi (1.4 MPa) with concrete substrate failure (typical).
