Supreme timber provides high quality postcrete for fixing domestic posts. All of our postcrete is ready to use, just add water, no mixing if required and comes in a waterproof plastic packaging. At supreme we offer two types of postcrete, a powder mix and aggregate mix both providing the same end result. The powder mix is pure powder and will set posts in 5-10 mins. To use, dig a hole to the correct depth and width depending on the post size, fill the hole to about a third of the depth with clean water, pour the postcrete around the post in the hole until no standing water is visible. Position and level the posts and sprinkle water on top of any remaining dry powder.
