Molded polystyrene lowers cost for forms for ducting in concrete
How forms used in forming ducts in concrete are made of injection molded polystyrene; plastic ducting may be left in place to make concrete stress resistant; costs are $1.70 for 100-mm (4 in.) diam in standard length of 1000 -mm; polyethylene lids are used when pouring concrete.
