Polyfibra is a polypropylene fiber added to fresh concrete to protect against plastic shrinkage cracking. Eliminates the need for wire mesh and reduces labor costs. Polyfibra is a low denier monofilament fiber that mixes with the concrete mass creating a very effective multi-directional secondary reinforcement.
Polyfibra is available to reinforce non-structural concrete applications with superior results.
Ideal for stamped concrete, conventional flatwork and precast applications. Fibrous reinforcement reduces concrete slab cracking, permeability and flaking or spalling. Always positioned properly, uniformed distribution of fibers through the concrete mixture assures proper placement of the reinforcement. Improves surface durability.
Polyfibra is available in 1.3 lb bags.
