Geotub is a reusable modular formwork system made from recycled plastic, specifically designed for the construction of round and oval concrete columns, as well as the rehabilitation of existing deteriorated columns. Introduced to the market in 2003, Geotub revolutionized the circular formwork sector by providing a lighter, more practical, and longer-lasting alternative to traditional timber, steel, or cardboard formwork systems.
Thanks to its modular design, Geotub allows the construction of columns with diameters ranging from 25 cm to 100 cm, ensuring fast installation, accurate geometry, and excellent concrete surface finishes. The system is particularly suitable for new construction projects, structural strengthening works, and infrastructure applications.
With a maximum component weight of only 10.5 kg, even in the largest diameter configuration, Geotub can be handled and assembled manually without cranes or lifting equipment. This makes it ideal for projects with limited access or restricted working spaces.
The smooth recycled plastic surface prevents concrete from adhering to the formwork, allowing for quick stripping and easy cleaning using only water, without the need for release agents or chemical products. The components are also designed for efficient stacking, optimizing storage and transportation both on-site and in the warehouse.
The place on-site and removal of GEOTUB are easy and fast thanks to the handles that allow the complete fixing of the formworks with a simple rotation by 90 degrees.
