Geotub: build round columns 44 % faster

Geotub is our reusable plastic formwork for the construction and reconstruction of round and oval columns. Since we launched it in 2003, it has become the go-to circular formwork in its field because, unlike traditional formworks, it enables easy and cost-effective casting of a large number of columns in record time, without the use of machinery.

Compared to cardboard formwork, for example, Geotub offers 44 % better speed performance in the casting of round columns:

An 80 cm diameter column casting speed:

GEOTUB

3.6 m per hour

CARDBOARD

2 m per hour

The almost double speed performance of the pouring process with Geotub is possible because:

  • It weighs max. 11 kg, offering quick and easy manual handling and installation,
  • It is durable, with 80 kn/m2 load resistance, and unaffected with humidity or weathering conditions,
  • It is easy to dismantle, leaving a perfectly smooth finish of the concrete, with no further treatment needed.

Along with the casting speed, Geotub offers many other advantages:

  • It is stackable and lightweight, speeding up the overall building process and greatly reducing the expenses of storage and transport,
  • Manual installation and less demand for heavy machinery make it convenient in regular working conditions and irreplaceable in busy or inaccessible worksites,
  • It is reusable and has its own set of accessories, producing significantly less waste and minimizing the amount of transport to landfills,
  • It is made of recycled plastic and can be rented, supporting sustainability and decreasing the amount of plastic waste.
