Monotub DD Range Features and Benefits
- Monotub DD Speed
An equal smooth column form which can be removed very quickly by pulling down the steel line that is the tube and functions as a 'zipper'. The inner foil (PVC) creates a slow maturing of the concrete, which benefits the strength of the concrete. - Monotub DD Spiral
The Spiral is suitable for dirty work, concrete assessment class 1 C. After the formwork has been removed, a spiral drawing will remain visible in the concrete surface. This formwork can also be made with a zipper. - Monotub DD Square/Rectangle
The form consists of the standard circular tube that is assembled with polystyrene parts. The product is finished on the inside with a hard inner plate. The square/rectangular version is suitable for concrete assessment class 1A/CUR 100. The tube is produced without a zipper as standard, as the tube can easily be cut open (with a knife or a grinder) on the polystyrene part without damaging the concrete surface. - Monotub DD Basic
The Basic is for infilling, often shorter pouring tubes. The tube is slid over the concrete pile head and poured with concrete. The pouring tube can easily be cut back to any length on site. The tube can also be delivered to the construction site in any desired length from the factory.
