4″ x 1/2″ Nomaflex Expansion
Nomaflex® Polypropylene Joint Filler is a high-performance, semi-rigid foam designed to set a new standard for concrete expansion joints. Unlike traditional materials, this closed-cell indexed foam is moisture-resistant, prevents 3-sided sealant adhesion, and can be used with both hot-pour and cold-applied sealants without a bond breaker. Its flexible yet durable design allows it to bend around circular structures easily, and it can be trimmed on-site with the Nomaflex Cutter to create a removable 1/2" void for professional sealant application.

Concrete Calculation Disclaimer:
Calculations provided by this tool are for estimation purposes only. Actual yardage may vary due to site conditions, such as uneven subgrade or bulging forms. To ensure you have enough material, it's recommended to add an additional 1/4 to 1 cubic yard to the calculator results. Depending on the subgrade's levelness, larger pours of 20 yards or more may require up to 10% additional.
