Description
Bag Column formers are a single use of formwork system that gives an excellent smooth fair face surface finish. The 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. Maximum pour height for sizes below is 6 metres , we can supply column formers up to 1200mm diameter.
