Sonotube Finish-Free fiber forms create smooth columns with no additional finishing required. Each is lined with a glass-like coating, which imparts a nearly flawless surface onto the concrete. The moisture-resistant, 100% recycled paperboard makes it lightweight and easy to handle.
Kolumn Forms construction tubes are disposable, one-piece cylindrical fiber forms for concrete columns, piers, pilings, and footings. The products are strong, lightweight, and moisture resistant. The high-impact plastic column liner eliminates spiral seams, which lets users avoid excessive finishing costs. Various widths and lengths are offered—the tubes also can be sawed to a specific size.
