2.1. Lay a bed of 0-¾ crushed stone 6″ deep at the bottom of every hole
2.2. Insert the concrete column form tube (sonotube).
2.3. Secure the cylinder by screwing it to an outer frame.
2.4. Make sure the distance between cylinder centres is indeed 6′.
2.5. Insert the post and steel reinforcing bar into the tube.
2.6. Pour the premixed concrete and water into the portable mixer.
2.7. Close the lid tightly and mix for 30 seconds.
2.8. When the concrete is ready, pour it directly into the tube.
2.9. Maintain the post in a vertical position, then use a post level or carpenter’s level to check that it’s plumb.
2.10. Make the concrete mound-shaped around the post; this will allow water to run off and not create a pool around the post.
2.11. Fill the cavity around the tube with stone dust up to ground level.
2.12. Lightly water the surface to compact the stone dust.
2.13. Always verify your measurements before you move on to the next post.
