Bio-based fibers for concrete, screeds and mortars like for example SikaFiber®-200 are micronized cellulosic fibers for use in concrete, screeds and mortars to help distribute cracks caused by drying and plastic shrinkage, and thus reduce the risk of early cracking. This natural fiber is an alternative for light crack control reinforcement.

Advancing Sustainable Concrete Through Bio‑Based Fiber Technology

For many years, Sika has been developing technologies that create measurable value across the entire construction value chain—from the responsible sourcing of raw materials and efficient manufacturing processes to product performance, durability, and end‑of‑life recyclability.

Within this framework, Sika has advanced bio‑based fiber technologies for concrete, supporting the transition toward more resource‑efficient and circular construction solutions.

Renewable Materials, Designed for Performance

The bio‑based fiber technology is based on plant‑derived cellulose fibers sourced from sustainably managed European forests.

SikaFiber®-200, to give an example, reflects Sika’s commitment to renewable raw materials, regional value creation, and reduced environmental impact. By replacing conventional fossil‑based synthetic fibers with fibers of natural origin, this innovative approach helps reduce plastic content in concrete while maintaining the high performance required for demanding construction applications. The result is a reinforcement solution that combines technical efficiency with improved environmental footprint.
