Fiber reinforcement is a must for nearly any concrete project. Used as a supplement or replacement for traditional reinforcement such as rebar, it can greatly improve the strength and durability of the concrete. This is especially true with UltraFiber natural cellulose fiber. UltraFiber cellulose fiber offers a host of benefits ranging from improved finishability and color acceptance to better bonding, dispersion, and crack control. UltraFiber and UltraFiber blends are the superior fiber reinforcement choice.
