What is post fix concrete used for?

Post fix concrete is specially designed to secure fence posts, gate posts, decking supports, and signposts quickly and firmly into the ground.

Does this mix require pre-mixing in a bucket or mixer?

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.

How long does it take to set?

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.

Can I reposition the post once the concrete is in?

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.

Is this concrete strong enough for heavy-duty installations?

Absolutely. Once cured, it provides a solid, durable base capable of supporting gates, heavy fences, and other structural features exposed to wind and load.

Not cheap but worth the money.

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.
