Nomaflex joint filler is a closed-cell extruded polypropylene foam joint filler that is easy to handle. Nomaflex also extends the service life of concrete by acting as an insulator for contraction and expansion joints. Trimmming the Nomaflex Expansion joint to create that 1/2 void for sealant has never been easier. Be sure to check out the Nomaflex Cutter here at Deco-Crete as well.
