Postmix from Stock

Postmix is our term for rapid setting pre-mixed concrete supplied on 20kg showerproof sacks for fixing concrete, metal or wooden fence posts, gate posts and railings.

We always keep postmix in stock so you can save time and money by picking up a few bags with your fencing materials.

Why use postmix from Procter?

Most fence and gate posts need to be secured into holes by using concrete. Traditionally fence erectors have had two options:

  1. Mix sand and cement on-site
  2. Get a supplier to deliver ready mixed concrete

Postmix has lots of benefits over these traditional options: 

  • Supplied in 20Kg strong shower proof non-slip bags
  • No waste of time on site either going to collect ready-mix from a local depot or waiting for a delivery to arrive
  • No waste of concrete, even if you get a bit more 'just-in-case' what you do not need, you can use on the next job
  • Ready to use, no mixing required on site, a correct mix every time making sure the posts are secure
  • Postmix sets in 5-10 minutes and fully hard within hours

We have calculated the volume of postmix for numbers and sizes of posts, make it convenient for you. You can buy as much as you need to use or to stock.
