The use of one way cardboard column formers in all kinds of construction work is considered to be very normal all over the European continent. Circular columns, supportive or only decorative, are adding extra dimensions to the interior or exterior of a building. However, cost reduction is the main reason for constructors to use Monotub DD as formwork for circular columns.
Monotub DD is produced out of recycled waterproof carton. The product is 100% water resistant and can be used in all possible weather conditions. Every storage on site can be done without the risk of damaging the quality of the formwork because of humidity or rain.
Another advantage of Monotub DD is the fact that the formwork can be removed at the moment suitable for you, which enables you to increase efficiency on manpower. Besides, the formwork can be used as column protection, after the concrete has cured.
