SikaFiber®

​

There are multiple reasons for adding fibers in concrete. One of the main benefits of fibers are the homogenous distribution in the concrete. Other benefits include:

​

  • Better cohesion of the fresh concrete

  • Control and reduce crack sizes due to early-age shrinkage

  • Improve flexural and shear strength

  • Improve load capacity and ductility

  • Increase toughness and abrasion resistance

  • Increase resistance to explosive spalling

  • Replace or partially replace traditional reinforcing steel

  • Save time in the construction process and reduce costs

​

Most micro and many macro fibers come in degradable “toss-in” bags for easy dosing.

Full list of Sika Fiber Products:

​

Micro Synthetic Fibers

(Primarily for plastic shrinkage & settlement crack control; improve early-age performance, impact/abrasion resistance, and durability)

  • Sika® Fibermesh® HP — Fine-denier monofilament polypropylene. High fiber count at lower dosage rates.

  • Sika® Fibermesh®-150 — Monofilament polypropylene. Standard micro fiber for general plastic shrinkage control.

  • Sika® Fibermesh®-300 — Fibrillated polypropylene. Can replace light-gauge wire mesh (e.g., 6x6 W1.4/W1.4) for temperature/shrinkage reinforcement.

  • Sika® Fibermesh®-150F — Monofilament polypropylene specialized for reducing fire-induced explosive spalling.

  • Sika® Fibercast®-500 — Monofilament or fibrillated polypropylene; often used in sprayed concrete and for green strength.

  • Sika® Fibermesh® FN — Nylon monofilament (hydrophilic). Excellent for plastic shrinkage and improved hydration/crazing resistance.

  • Sika® Fibermesh® AC 100 — Acrylic monofilament micro fiber.

  • ​

Macro Synthetic Fibers

(Structural performance – flexural toughness, residual strength, crack-width control; can replace or reduce wire mesh/rebar in many slab applications)

  • SikaFiber®-800 Stealth — Self-fibrillating macro fiber designed for excellent finishability (including hard-troweled slabs).

  • SikaFiber®-820 Stealth TW — Twisted-bundle version of Stealth for easy batching and high fiber network.

  • Sika® Fibermesh®-650 — Graded macro-synthetic fiber; widely used cost-effective secondary/structural reinforcement.

  • Sika® Fibermesh®-650 S — Version optimized for higher energy absorption (shotcrete/sprayed concrete).

  • SikaFiber® Enduro® Prime — High-performance crimped macro fiber; strong residual strength and DOT acceptance in many states.

  • SikaFiber®-54 Force — Embossed macro fiber with good energy absorption for concrete and shotcrete.

  • SikaFiber® Force-48 — 48 mm macro fiber optimized for high energy absorption in sprayed concrete at lower dosages.

  • ​

Steel Fibers (SikaFiber® Novocon®)

(High toughness, impact resistance, and load-carrying capacity; Type I, II, or V per ASTM A820)

  • SikaFiber® Novocon® XR — Type V (crimped).

  • SikaFiber® Novocon® CS-1000 — Type II.

  • SikaFiber® Novocon® HE-4550 — Type I hooked-end.

  • SikaFiber® Novocon® CHE-6560 — Type I collated hooked-end.

  • SikaFiber® Novocon® CHE-8060 — Type I collated hooked-end.

  • SikaFiber® Novocon® CHE-6535 — Type I collated hooked-end (also suitable for sprayed concrete and thinner sections).

  • SikaFiber®-6513 UHPC — High-strength steel fiber for ultra-high performance concrete applications.

  • ​

Blended Fibers

(Combine micro + macro or micro + steel benefits in one product)

  • SikaFiber® Novomesh®-850 — Steel (Type V) + micro-synthetic blend.

  • SikaFiber® Novomesh®-950 — Macro-synthetic + micro-synthetic blend.
