Pressure grouting is a method that strengthens soil or concrete by injecting grout under pressure. The process involves these steps:
1. Preparation: Identify voids or weak areas in the substrate.
2. Drilling: Drill holes at strategic locations to access the affected areas.
3. Grout Mixture: Prepare a grout mixture based on the project’s requirements.
4. Injection: Inject grout into the holes under controlled pressure, filling voids and compacting loose soil.
5. Monitoring: Monitor the injection process to ensure even distribution and avoid over-pressurization.
6. Curing: Allow the grout to cure and harden, enhancing the substrate’s strength and stability.
Pressure grouting offers effective solutions for soil stabilization, foundation repair, and structural reinforcement.
