Postcrete vs Concrete

by Sam Wood | Last Updated: 05/07/2021

If you have ever set posts then you will have no doubt seen, or been told about, postcrete. But what exactly is postcrete? and how does it differ from good old concrete? Well, I have done all the research possible and have outlined all the differences below, so let’s get stuck in!

Postcrete Vs Concrete

So what exactly is the difference between these two? Well the most obvious, and the one you will notice straight away, is how you use the two. Postcrete is much easier to use than concrete, no mixing is required, just chuck it in your post hole add some water and away you go.

No mixing required with postcrete

When using postcrete all you have to do is add water to your post hole and then chuck the postcrete in. That’s it, no mixing at all. The postcrete will then proceed to set over 15-20 minutes from my experience. Contrast this with concrete which you have to pre-mix and mix well before putting it anywhere and you can see that postcrete is much easier to use, when setting posts at least.

For concrete, you also need to order sand and ballast, then mix this in well to make concrete. You will also need a mixer if you are making a lot of concrete. You can use a bucket or even just the floor, but this can be slow or in the case of the floor, messy.

Setting time

Concrete can take a long time to set, sometimes even up to a few days before it fully hardens. Whereas postcrete will go hard in a few minutes and be fully set in a few hours. This, along with ease of use, is one of the main advantages of postcrete over concrete.
