Nomaflex® is an engineered foam joint filler that outperforms asphalt impregnated fiberboard and sets a new standard for concrete expansion joint fillers. It is a semi-rigid, closed-cell polypropylene foam that simply performs better and installs faster.
Plus, the innovative Nomaflex Cutter tool enables concrete installers to easily trim Nomaflex on the job site or pre-score a removable 1/2” void for use with sealants. This saves labor and money by eliminating the need for an additional void cap system.
