Static Injection Method (suitable for cracks of more than 0.2mm)

1. Check crack: As for the cracks of more than 0.2mm, if the surface has no leakage, static injection can be applied. 

2. Crack treatment: Clean up installation area, remove the concrete surface precipitates and keep the surface clean. Use alcohol or ace tone to clean the shallow surface of crack and the surface of crack mouth.

3. Install injection base: The order of base installation is down-up; horizontal surface can start from one end, each single hole is continuously operated one by one. The spacing of base installation is 300mm.

4. Seal crack: Use special crack sealing adhesive or other anchoring adhesive to seal the cracks which are need to be injected, and they should be fully sealed. Reserve the observation outlet on the top of the crack.

5. Seal check: Check the sealed cracks to ensure there is no air leakage.

6. Adhesive mixing: Mix the crack filling adhesive by required ratio of factory. Mix the adhesive according to your actual amount, don't mix too much to waste.

7. Adhesive injection: Fill injection tool with mixed adhesive, and place the injector on the base for injection. The time of injection is about 0.5~1 hour, depending on the real condition of injector without adhesive leaking and reserved observation outlet with adhesive exudation. If the adhesive in the injector is used up, you need to refill for injection. 

8. Remove injector, cure and maintenance: After full injection, remove the injector in time. Block the base by a stopper, do not remove the base and crack sealing parts until 12 hours of cure and maintenance.

Required accessories: pressure injector, injection base, stopper, brush

High-pressure Grouting Method (suitable for all cracks)

1. Clean treatment: Check and analyze the leakage carefully to determine the position and spacing of grouting holes. Clean up installation area, remove the concrete surface precipitates and keep the surface clean.

2. Drill holes: Drill holes by electric hammer drilling tools along the crack, the diameter of drill bit is 14mm, the angle of drilled hole is better to be ≤45℃, the depth of drilled hole is ≤2/3 of structure thickness, the drilled hole must be through the crack. But the structure (except post wall grouting) should not to be drilled through. The spacing between drilled hole and crack is ≤1/2 of structure thickness. The spacing of drilled hole is 20cm~60cm.

3. Embed nozzle: Install the grouting nozzle (also known as water-sealing needle) in the drilled hole, and use special hexagon wrench to tighten to make sure there is no gap around the grouting nozzle and drilled hole, no leakage.

4. Wash crack: Inject clean water to grouting nozzle at a pressure of 3Mpa with high pressure washing machine to observe the water leakage condition, and wash up the dust in the crack.

5. Seal crack: When washing crack if you find the water leaking crack surface, use fast-cure cement to seal it in order to prevent adhesive leaking during grouting chemical adhesive.

6. Grout adhesive: Use high pressure grouting machine to fill chemical adhesive into holes. The order of vertical surface grouting is down-up; horizontal surface can start from one end, each single hole is continuously operated one by one. When the neighbor hole starts to pour out, keep the pressure for 3~5 minutes and stop grouting, then grout the neighbor hole.

7. Remove nozzle: After finish adhesive grouting, check there is no leakage then remove the nozzle or knock out the exposed nozzle. Clean up excess leaked and cured adhesive.

8. Sealing treatment: Repair and seal the mouth of crack grouting by fast-cure cement.

Required accessories: grouting machine, water-sealing needle, brush, measuring spoon

Application:

*Suitable for crack repair in concrete project

*Widely used for concrete interior defects(honeycomb, porosity ) injection repair,

*Hollowing wall and floor tile filling
