Step 1: Dig the hole to the right size

Make the hole wide and deep enough for the post to sit securely. Leave space around the sides so the postcrete can form a solid base.

Step 2: Position the post

Set the post in the hole and check it is upright with a spirit level. Use temporary supports if needed, as once you add water the mix will start to set quickly.

Step 3: Add the dry mix

Pour the postcrete into the hole around the post until it reaches the required level. Keep the post steady while you do this so it does not shift.

Step 4: Add water carefully

Pour in the recommended amount of water slowly and evenly around the mix. The material will start binding fast, so work methodically and do not overwater it.

Step 5: Leave it to set

Check the post one last time for plumb, then leave it alone to harden fully. Avoid loading the post too soon, as moving it early can weaken the setting process.

💡 Pro Tips

• Have everything ready before you start, as postcrete sets quickly.
• Keep the post level while the mix goes in to avoid adjustments later.
• Use gravel at the bottom of wet ground for better drainage.
• Read the setting time on the bag before hanging any weight on the post.

⚠️ Safety First

Wear gloves and avoid breathing in dust when pouring the dry mix. Keep water, tools and the post set-up within easy reach before you start.
