How it works

EXPANDA-CRETE USAGE

How much Expanda-Crete high density post hole foam do you need?

With one Expanda-Crete pack equivalent to around 20 bags of rapid set cement you are going to save a lot of room on your ute.

30mm of Expanda-Crete mix in the bottom of any straight sided hole, will swell to 500mm.

60mm will fill a metre. If there is a post standing in the hole, it doesn’t take very much to fill 30 or 60 mm.

With concrete you need a bigger hole, just to get it down there. Because Expanda-Crete expands with pressure from the bottom, the hole can be smaller and do a better job.



These tables will help you work out how much Expanda-Crete high density post hole foam you will need for your next project.

The Expanda-Crete useage chart is a guide to how many ml required per hole.
Assume standard hole depth is 1000mm
