Monotub DD is made of materials whose mechanical resistance is higher than cardboard. It is also thinner and lighter than cardboard, but much more resistant.
Monotub DD is lightweight and therefore quick and easy to handle in the yard. Just two fixing systems are needed to set it up: one at the base and the other at three quarter height.
Monotub DD is time saving because it can be easily filled in a few seconds. Vibrate the concrete every 50 centimeters in order to achieve an optimum fair facing finish.
Monotub can be removed at any time, either the very next day or even a year later. The part that comes in contact with the concrete is polyethylene therefore it does not stick. Cutting is carried out in a few seconds with a metal wire inserted inside the tube, thus making you save a great deal in terms of labor. Monotub DD is ideal for columns with fair facing finishes because the formwork can stay on up to the termination of the construction works in order to protect the column.
