For the last century, concrete installers have been using asphalt impregnated fiberboard (AIFB) as an expansion joint filler. Today, installers have a new choice in Nomaflex, a closed-cell polypropylene foam expansion joint filler and form, which has been evaluated by the American Association of State Highway and Transportation Officials (AASHTO).
With positive industry feedback from the product’s initial introduction in select sizes last year, Nomaco is now introducing a full product line of 30 plank sizes in thicknesses ranging from ½ inch to 1 inch and widths from 3 ½ inches to 8 inches. Nomaflex will be available in sheet form in January 2017.
Nomaflex extends the service life of concrete by acting as a filler for full-depth expansion joints in sidewalks, streets, driveways, highways, airport runways and other applications. North Carolina-based Nomaco developed the product to solve common problems for installers, including concrete joint sealant failure, difficult installation, product breakage and on-going joint maintenance challenges.
