What is Post Mix??

Post Mix Concrete is a ready-mixed concrete, a mixture of cement and ballast. It’s sometimes referred to as Postcrete and is specifically designed for erecting timber, concrete or metal fence posts. It’s also ideal for smaller jobs around the garden where you need to set objects such as pots or ornaments in place.

Why is it so popular?

Post Mix saves time and effort as the mixture is already made up and ready to use no heavy mixing required. You will also end up saving money as you just make up what you need each time. With Post Mix you are only buying what you’ll use as it’s available in conveniently-sized bags, ready for mixing whenever you need it.

So, how do you use Post Mix Postcrete?

You will need about one and a third of bags of Post Mix Concrete for each hole for 75 x 75mm and 100 x 100mm fence posts. That’s about 11 bags of Post Mix for eight fence panels. Gate posts, which work harder than posts due to gate movement might use three to four bags.

The posts should be buried from 600mm (2ft) to 750mm (2ft6″) into the ground, depending on the height of the fence, you should be placing the Post Mix around the post, but trying to not get any underneath. (Otherwise the concrete can trap water and soak the post, causing it to decay.)

If the ground the post is in isn’t free-draining then a small layer of shingle can be placed under the fence post to help drainage.


Pour half a bag of Post Mix Concrete into the hole using more for larger holes and posts. Using a watering can with a fine rose, pour clean water around the posts base. After just two minutes don’t walk away, keep checking vertical alignment of the post with the spirit level.

Adjust post positioning if needed. Repeating this process, pouring water onto the post at ground level until the hole is filled. Setting takes only 15-20 minutes.

Full instructions are also printed on every 20kg bag of Post Mix Concrete making it easy. A video of fitting concrete posts can be found here
