Formliner is a lightweight and extremely strong spiral tubing which is suitable for forming pour in place round concrete columns.
A spiral formatube from EzyTube
ensures a high burst strength at a thin wall thickness resulting in a lightweight formatube that is easy to cut to remove after pouring.
Using a spiral winding technique the formatubes are manufactured in various diameters ranging from 200mm to 900mm, in 50 mm intervals.
Once concrete has been poured within the tube, the surface of the concrete columb shall reflect the spiral seam on the outer surface of concrete.
A wall structure which is semi flexible means that the tube has a high resistance to impact and will spring back to shape If it’s out of round after transport or been compressed.
