Macro Synthetic Fibers

Our high-performing polymer macro fibers offer the performance of steel fibers at lower dosage rates. The unique anchorage system of each macro synthetic fiber and the higher aspect ratio (length/diameter) allows for higher performance in the concrete matrix. The macro synthetic fibers infuse the concrete with added levels of toughness, energy absorption, and durability. In addition, macro synthetic fibers provide an added measure of crack control, without the risk of corrosion associated with steel.

The high-tech macro fibers are specifically designed for certain applications, such as; slab on ground or shotcrete.  When used in slab on ground the fibers aspect ratio (length over diameter) plays an important role in distributing stresses. The three dimensional reinforcement leads to reduction in cracks, impact resistance, and additional load caring capacity. Sika’s newest fiber, the SikaFiber®-800 Stealth, also incorporates a low fiber memory which leads to better finishability.

When used in shotcrete applications, the SikaFiber® reinforcement provides increased adhesion, so you'll not only experience less rebound and waste, but you will also be able to apply thicker layers of shotcrete in one pass. Fiber reinforced shotcrete offers greater energy absorption, a more efficient rock section profile, improved ductility, fracture toughness, and offers simpler application logistics.
