1. Prepare the area: Before starting the compaction procedure, ensure that the area is clean and free of any debris or obstructions. Make sure that the formwork is properly installed and secured.
2. Position the poker vibrator: Place the poker vibrator at regular intervals across the surface of the suspended concrete slab. The spacing between each vibrator should be determined based on the size and thickness of the slab.
3. Start the vibrator: Turn on the poker vibrator and insert it into the concrete at a slight angle. Begin vibrating the concrete by moving the vibrator in a systematic pattern across the surface of the slab. Make sure to penetrate the concrete to the desired depth to ensure proper compaction.
4. Continue vibrating: Continue vibrating the concrete slab in a systematic manner, moving the vibrator across the surface in a grid pattern. Pay special attention to the edges and corners of the slab to ensure that all areas are properly compacted.
5. Check for air pockets: As you vibrate the concrete, be on the lookout for any air pockets or voids that may form. Use the poker vibrator to fill in these areas and ensure that the concrete is evenly compacted throughout.
6. Monitor the progress: Keep a close eye on the compaction process to ensure that the concrete is being properly compacted. Adjust the speed and frequency of the vibrator as needed to achieve the desired level of compaction.
7. Finish the compaction: Once the entire surface of the suspended concrete slab has been vibrated, turn off the poker vibrator and allow the concrete to set and cure according to the manufacturer's instructions.
8. Clean up: Remove the poker vibrator from the concrete and clean it thoroughly to prevent any buildup of concrete residue. Dispose of any waste materials properly and ensure that the work area is left clean and tidy.

Outline of Compaction Procedure for Suspended Concrete Slab Using a Poker Vibrator
1. Preparation
- Ensure the concrete mix meets specifications. - Set up the formwork and reinforcement securely.
2. Placement of Concrete
- Pour the concrete into the formwork in even layers, typically 150-250mm deep. - Avoid overworking the concrete at this stage.
3. Vibration
a. Insertion of Poker Vibrator:
- Insert the poker vibrator into the concrete at 300-450mm intervals, ensuring they reach the bottom of the slab. - Hold the vibrator vertically.
b. Vibration Duration:
- Vibrate the concrete for 10-15 seconds per insertion point. - Continue vibrating until the concrete appears level and consolidated, with air bubbles removed.
c. Overlapping Pattern:
- Vibrate the concrete in an overlapping pattern to ensure uniform compaction. - Each insertion point should overlap the adjacent points by 50-75%.
4. Finishing
a. Screeding:
- After compaction, use a screed to level the surface of the concrete. - Strike-off any excess concrete.
b. Smoothing and Floating:
- Use a float to smooth the surface of the concrete and eliminate any irregularities or voids. - Float the concrete in two directions perpendicular to each other.
5. Curing
- Cover the cured concrete surface to prevent moisture loss and promote proper hydration.
Additional Tips:
- Use a sufficiently powerful vibrator to ensure adequate compaction. - Avoid over-vibrating the concrete, as it can weaken the structure. - Monitor the concrete for settling and adjust the vibration pattern accordingly. - Check the slab's thickness and level after compaction to ensure it meets specifications.
