I have just finished pouring my cement pier and have 1.7M of 12 inch diameter formatube left over (I could only buy it in a 3M length). If you are looking at building a permanant cement pier, the price is $50 for anyone who would like to come & pick it up in Nth Western Sydney.
would love to get the formatube but itis a bit short for my needs - I need about 2.5 m - where did you end up buying it? I tried bunnings at rockdale - no luck
and if you dont mind how much did you pay ??
Sorry for the delayed response to the below questions.
I picked up the formatube from Hardware & General in Brookvale. The price for 3M length was $110.
