Why Nomaflex?

2017 Winner

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 D8139, and ASTM standard specification D1751 for extrusion, compression recovery and water absorption as tested per ASTM test method D545.
