Column formers Tubbox^®

Use of a plastic insert in Tubbox^® column formers creates a "smooth" concrete surface with occasional blowholes.

Tubbox^® "spiral" column formers produce a concrete surface with a normal blowhole pattern and a slight impression of the helical structure of the pipe.

The column former is an economical and functional solution.

In Tubbox^® "blowhole-free" column formers, the inserted Zemdrain^® CPF liner ensures a largely blowhole-free surface and increases the surface hardness of the edge-concrete layer.

In addition to round and rectangular concrete columns, Tubbox^® column formers are available in a variety of special forms:

• custom cross sections, e.g. ellipses, polygons, L-shapes
• conical columns
• angled columns
• With integrated thermal insulation

We can also produce custom designs according to your preferences and drawings.
