Description

The Formwork Tube, also known as the Construction Sonotube, is a cardboard tube used as an easy technique for constructing or forming circular columns made of reinforced concrete.

In construction, it’s the most economical way to build round concrete columns. The cardboard structure helps reduce construction times, which is why formwork is the preferred option over wood or metal, as it’s durable and doesn’t deform during casting.
