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” to 1” and widths from 3 ½” to 8”. 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.
Nomaflex is:
- An inherent bond breaker – When using sealants, no bond breaker is needed. This reduces cost and improves installation time. Nomaflex does not impede cure time.
- Waterproof – Nomaflex will not absorb water and will remain in place for years.
- Lightweight – Nomaflex weighs 75% less than competing asphalt impregnated fiberboard products, making it easy for one person to carry multiple bundles.
- Flexible – Nomaflex can be used as a form, bending to a 12-inch diameter if needed, but it is rigid enough to pass across wet pours without breaking.
- Inert – Nomaflex resists oils, gas, salts, acetone & other chemicals.
- Clean & Durable – Nomaflex has no sticky residue, does not leach and will not break or flake.
- Easy to Install – Nomaflex can be nailed or staked and is compatible with plastic edge caps to leave void for sealants.
- Re-usable & Recyclable – Nomaflex can be used multiple times as a form to reduce cost and waste. Made of polypropylene, it is also recyclable.
