Formwork Direct Cardboard Column Formers are a single use formwork system that gives an excellent smooth fair face surface finish. Our Column Formers are manufactured by welding together several layers of high quality polyethylene coated kraft paper, which are spirally wound and bonded together by heating the polyethylene.
Once this step is complete, a water resistant foil is also spirally wound over the kraft paper, sealing the column against humidity. This manufacturing process requires no additional adhesives which reduces the wall thickness, making the Column Formers light and easy to handle.
Designs
Lined – BAG ® Column Formers have a PVC liner which is fitted the whole length of the inner diameter of the Column Former, this provides an impeccably smooth finish. BAG ® Column Formers will only leave a hairline seam on the concrete from the point where the liner joint meets.
Unlined – BAG ® Column Formers are also available unlined for applications where surface finish is not critical. This Column Former will leave a spiral effect on the finished column.
Square – We can offer square or rectangular columns on request, made from the standard Column Former with an additional polystyrene insert, manufactured to your specific requirements.
Bespoke – We can also offer made to order bespoke designs. Please contact our sales team for more details.
