## Questions & Answers

**Q: What is post fix concrete used for?**
A: Post fix concrete is specially designed to secure fence posts, gate posts, decking supports, and signposts quickly and firmly into the ground.

**Q: Does this mix require pre-mixing in a bucket or mixer?**
A: No. This is a dry pour product – simply pour the concrete mix directly into the post hole and add water. No tools or mixing equipment needed.

**Q: How long does it take to set?**
A: Post fix concrete sets in approximately 5 to 10 minutes depending on weather and ground conditions. Avoid moving the post during this time to allow for proper curing.

**Q: Can I reposition the post once the concrete is in?**
A: You have a few minutes after pouring to ensure the post is straight. After that, the mix will begin to harden rapidly, so quick adjustments are essential.

**Q: Is this concrete strong enough for heavy-duty installations?**
A: Absolutely. Once cured, it provides a solid, durable base capable of supporting gates, heavy fences, and other structural features exposed to wind and load.

## Customer Reviews

### ⭐⭐⭐⭐⭐ A very good product.
*by A***R on 31 August 2025*

So easy to use and quick to dry

### ⭐⭐⭐⭐⭐ Not a bad price, works well
*by J***S on 11 January 2026*

Works well. We used a piece of bamboo to put channels in the mix for the water to get to the bottom layers. Dries quickly. Our arch is now solid as a rock. Very happy

### ⭐⭐⭐⭐ Not cheap but worth the money.
*by B***N on 5 July 2025*

More expensive than a local store, presumably because of the weight. I used it for a rotary drier, with the hole half filled it held the pole firmly whilst I fiddled with a spirit level. It then set quickly with no need to prop it in place.
