Repairing concrete cracks can prevent the development of cracks and corrosion of steel bars. It plays an important role in improving the durability of concrete. As a crack repair material, its performance is directly related to the long-term performance of crack repair.

1. The crack width Iis 0.1mm≤ω≤1.5mm, can be injected into a low viscosity structure adhesive by pressure perfusion method. Mainly through the pre embedding glue nozzle, sealing cracks, pouring the adhesive to complete the repair of cracks.

2. Pressure grouting + bonding carbon fiber cloth reinforcement

The crack width is more than 1.5mm Omega cracks, and cracks in the cross region, determine a structure cracks, based on pressure perfusion, along the crack externally bonding carbon fiber, increase tensile bearing capacity.

3. Surface sealing method

The crack width is less than 0.2mm Omega independent cracks or crack, crack repair glue can be used closed fracture channel. For the floor and other parts that need to be impermeable, it is better to paste the fiber material on the crack surface to enhance the sealing effect.

The repair of concrete cracks can prevent the further development of cracks, and further deterioration of concrete caused by further corrosion of steel bars. It plays an important role in improving the durability of concrete. As a crack repair material, its performance is directly related to the long-term performance of crack repair.
