K-FORM®

Control Joint K-Form has created a revolution in concrete placing. A lightweight cast in-place permanent screed rail that’s strong enough to handle all types of conventional mechanical screeds.

K-Form is made from uPVC. In simple terms it’s a lightweight cast in-place permanent screed rail that’s strong enough to handle all types of conventional mechanical screeds.

It’s fast and easy to put in place. Plus it provides control, construction and isolation joints. In other words, you set up, pour and the K-Form simply stays in the ground.

 

  • Comes in 2.8m Lengths for ease of handling.
  • Ultimate construction joint for external hard stands, driveways, residential slabs and warehouse applications where steel joints are not needed.
  • Speed up your construction – no delays stripping formwork from ‘Hit and Miss’ pours
  • Non – Corrosive so ideal for those application where chemical or salt corrosion is an issue
How it works

Australasia’s premier Construction Joint System

Placing concrete has traditionally involved setting up a series of wooden boxes and then concrete is poured into alternate sections.

After the concrete has dried, the boxing is dismantled and a new load of concrete goes into the sections missed the first time around – hence the name ‘hit and miss’ pouring.

While this method of pouring concrete is well-established and fairly straightforward, the process has always had drawbacks. A major issue is the amount of time it takes – because you’re being forced to sit through the drying process before you can pour again. Cutting control joints into the concrete with a diamond saw adds more time on top this
