Carbon Fiber Reinforced Polymer (CFRP) is widely used in the concrete repair industry. It is lightweight with tremendous tensile strength, meaning it resists forces that try to pull it apart. 

Carbon fiber strengthening is a method of reinforcing concrete and masonry structures using carbon fiber composite materials. The process involves the bonding of thin, high-strength carbon fiber sheets to the surface of the concrete or masonry using a specially formulated adhesive. The carbon fiber sheets provide additional strength and stability to the structure, helping to prevent cracks and other forms of damage.

Carbon fiber strengthening is used to reinforce concrete and masonry structures that are showing signs of deterioration, such as cracking, spalling, and other forms of damage. It is also used to retrofit existing structures to meet current design standards and improve their overall performance.

One of the key benefits of carbon fiber strengthening is that it is non-invasive, meaning that it does not require the removal of any existing material. It can also be used in hard-to-reach areas, making it an ideal solution for structures with limited access.

Another advantage of carbon fiber strengthening is that it is lightweight, which means that it does not add significant additional weight to the structure. This makes it ideal for structures that are already at or near their weight-bearing capacity.
