Processing Flow
Crack confirmation and marking → Crack treatment → Seal the crack and fix the injection gun base
→ mix the adhesive according to the ratio → low pressure injection → hardening and maintenance
The interval setting according to the crack width as blow:
Crack width (mm) | Interval (mm) | ||
Min. | Standard | Max. | |
0.05-0.2 | 150 | 200 | 250 |
0.2-3.0 | 250 | 300 | 350 |
