Bag Column formers are a single use of 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. Once this 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 BAG Column formers light and easy to handle.
Lined – BAG Column Formers have a PVC liner which is fitted the whole length of the inner diameter the Column former, this provides an impeccably smooth finish. BAG column formers will only leave a hairline seam on the concrete form 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.
