    Fibrillated Microfibers

    Replacement of light gauge weld-wire reinforcement

    Fibrillated polypropylene fibers are an unique technology that creates additional micro fibrils that are attached to the principle fibrillated network. These additional anchorage sites provide increased bonding between the mortar matrix and the fiber network and enhance the performance of fibrillated microfibers as a shrinkage and temperature (secondary) reinforcement.

    • Excellent distribution throughout concrete
    • Useful in residential and commercial slab-on ground
    • Excellent finishability
