Eliminate stripping and deliver a superior floor finish

The innovative Canzac Column Isolation Form was developed to optimise programme flexibility, minimise forming time, eliminate stripping and deliver a superior floor finish. It is a robust galvanised steel leave-in-place profile manufactured to any shape including square, half-square, round and half-round.

Supplied with fixing brackets to panels and height adjustable brackets that fix to the top of column foundations. The form is left in place, so no stripping is required.

Many types of building i.e. distribution centres, manufacturing facilities, warehouse and retail buildings are constructed with vertical structural steel column supports that carry the load of the structure, roof and other building components. When constructing these buildings concrete foundations are generally poured at pre-determined locations through the length and width of the building. These foundations support the columns and column loads and are usually connected by the way of anchor bolts that are cast into the foundation on which the column is supported. The main slab on grade is prepared and poured after the structure and the roof is in place but sometimes the slab is poured first.

Features and Benefits

  • Enhance programme flexibility
  • No stripping or patching required
  • Eliminates waste
  • Can be manufactured to specific requirement
  • Allows for expansion and contraction
  • Superior floor finish
  • Optional capping rebate formers to the top of the former for placement of joint filler



It can be used in small or large concrete and steel structures where isolated columns are placed through the concrete slab and directly onto the bolted connections embedded in the concrete foundations. The slab is then placed over the foundations and subgrade. This system can be used for conventional, fibre-reinforced and post-tensioned concrete slabs.
