Geopanel Star for (Almost) Any Column Shape

The Geopanel Star plastic column formwork system for concrete structures is a universal solution for the forming of columns, pile caps, footings, plinths, and more.

Create a wide-range of column forms with ease. Each high-strength, ABS plastic panel can be adjusted in 5 x 100 mm increments, making a small kit usable for many job types – big and small.

Geopanel Star panels are connected using the nylon handle with a simple 90 degree twist. Tie rods and anchor nuts are used to prevent bulging on larger width columns.

Because the Geoplast Star column formwork system is made from high-strength, lightweight ABS at less than 10 kg per piece, crane time can be drastically reduced.

Smart formworkers are experiencing a significant saving of time and resource costs to their jobs.
