  • Nomaflex Cutter

Named as one of the 2017 Most Innovative Products at World of Concrete, Nomaflex is easy to handle and extends the service life of concrete by acting as an insulator for contraction and expansion joints. It can be used with hot-pour or cold-applied sealants. Nomaflex prevents three-sided adhesion and can be used without a bond breaker. It also has no odor or sticky residue and is resistant to oils, gas, salts and other chemicals.

Nomaflex can be stored outside and will not absorb water, break, flake or leach. It is flexible, yet rigid enough to be passed across a wet pour and can be used as a form. Nomaflex is less expensive to install and can be installed using traditional installation methods. Common residential, commercial and industrial installations using Nomaflex include, but are not limited to: sidewalks, streets, driveways, highways and airport runways.

Nomaflex fully complies with ASTM standard specification D 8139, and ASTM standard specification D 1751 for extrusion, compression recovery and water absorption as tested per ASTM test method D545.

The intrinsic properties of Nomaflex include:

  • Waterproof
  • Ultra lightweight
  • Flexible
  • Does not impede sealant cure time
  • Durable
  • Clean product
  • Less breakage
  • Inert
  • Easy to use, same installation methods as currently used
  • Can be used with hot-pour and cold-applied sealants
  • Recyclable / reusable
  • Made in USA

Nomaflex Cutter

The newest addition to the Nomaflex joint filler system, the Nomaflex Cutter is an innovative scoring tool that won Most Innovative Product at the 2018 World of Concrete show. The Cutter enables installers to create a void when sealant is required, eliminating the need for a separate void cap system.


“Wanted to send you an email to let you how great the Nomaflex works for us. It is a great product and so much easier to store and use without worrying about rotting and breakage. The look is so much better and the customers we use it for like it a lot.”
Jimmy Whitley, Jymco Construction Company, NC
