Professional-grade reinforced foam expansion joint material designed for creating durable, flexible expansion joints in concrete slabs, driveways, and sidewalks. Manufactured by NOMACO with Nomaflex reinforced construction for enhanced strength and longevity. The 1/2" x 3-1/2" x 5 feet dimensions provide convenient length for standard residential projects with thinner slabs while the black color and reinforced foam absorbs expansion and contraction movement with superior durability, preventing cracking and damage in concrete structures subjected to temperature changes and seasonal movement.
