Kwik Tube Square Columns

SPI can provide Kwik Tube square and rectangular columns or other shapes to the specific requirements of your formwork project.

The process of setting up and stripping is fast and easy.

We use a high strength outer round tube that is fracture resistant. The internal component incorporates a high density polystyrene foam segment that creates the required shape. An inner liner is placed to ensure a smooth concrete finish.

Product features:

  • Save time, costs and labour

  • Highly customisable solutions

  • Quick to assemble
  • Lightweight, easy to transport

  • Environmentally friendly – made of non-hazardous materials, 100% recyclable

  • Rigid for piling, flexible for various applications

  • Waterproof, designed for underwater applications with no effect on strength

  • Offered in a range of finishes – including spiral lined, textured and bespoke designs


With the correct recommended handling procedure, these column forms can be reused numerous times.


Please note that after the initial use and stripping a new external tube is essential for reuse to attain the shape and finish of the square or rectangular concrete column.
