Concrete columns can be produced in different geometries and surface qualities with Tubbox® column formers. They are a time-saving and cost-effective alternative to conventional column formwork.
The disposable column formers are equipped with a ripcord for easier removal.
Advantages
Fast set up and stripping accelerates construction
Easy and handy for transport and installation
Eliminates time and costs of cleaning and return transport
Several columns can be produced in one concreting period
Special coated inserts in the Tubbox® "straight-edged" column formers allow the production of columns with square or rectangular cross sections.
The column form has chamfered edges as standard, special versions are available on request.
Column formers Tubbox® – smooth finish
for circular columns
Use of a plastic insert in Tubbox® column formers creates a "smooth" concrete surface with occasional blowholes. With a column former diameter of more than 600 mm, two vertical joints of the column former insert are visible.
Column formers Tubbox® – spiral finish
for circular columns
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.
Column formers Tubbox® – blowhole-free finish
for circular columns
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.
Column formers Tubbox® – custom shapes
for individual cross-sections as well as conical and angled columns
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.

To insulate external columns, the insulation is often applied after concreting. This is difficult due to the geometrical form of the columns. With a special Tubbox® column formers, the insulation is already integrated during manufacture.
