1. Crack Inspection and Method Selection: Inspect the crack area, its condition, width, and depth before construction to determine the appropriate repair method and the viscosity of the injection material.

2.Surface Cleaning: Cleaning the repair area is essential to prevent reduced injection volume and surface adhesion due to contaminants. Remove dirt and dust using brushes and grinders, and clean any grease with solvents such as thinner.

3.Anchor Placement: For concrete thicknesses between 20cm and 30cm and cracks less than 1mm wide, it is standard to install four anchors per meter at 25cm intervals. Adjust the number of anchors based on the structure’s thickness and crack characteristics. For slab reinforcement, it is effective to perform injection work from the lower ceiling of the slab to be reinforced, excluding the bottom surface of the slab. Anchor placement may vary depending on the crack pattern.

4.Anchor Installation: Attach and secure the anchors using epoxy sealant (dry or wet type).

5.Crack Sealing: To prevent leakage of the injected epoxy resin outside the crack area, seal cracks other than those covered by anchors with epoxy sealant (dry or wet type), with a thickness of 1mm and width of 3-5cm. Ensure the sealant is fully cured before proceeding with the injection.

6.Epoxy Injection: Use a low-pressure injector (Micro Capsule) to

 inject epoxy into the already installed anchors, skipping one anchor at a time. For uninstalled anchors, set up syringes for injection. If the epoxy resin in the injector cylinder depletes before reaching its curing time, quickly replace the syringe and continue the injection process.
