Sika, GCP Applied Technologies and Master Builders Solutions are three globally recognised suppliers of construction-grade polypropylene (PP) fiber for concrete and mortar reinforcement, widely specified in civil engineering, industrial flooring, shotcrete and precast concrete projects.

Sika (SikaFiber® PP Series)

Sika’s flagship SikaFiber® PP portfolio includes virgin PP monofilament microfibers and deformed macro synthetic PP fibers. Micro PP grades including SikaFiber PPM‑12 and Fibermesh control early-age plastic shrinkage and settlement cracking. Macro PP fibers such as SikaFiber Force deliver post-crack energy absorption, acting as secondary structural reinforcement. The full SikaFiber range complies with EN 14889‑2 and ASTM C1116 Type III, manufactured under ISO 9001 quality systems for slabs, screeds, sprayed concrete and tunnel works.

GCP Applied Technologies (Adfil®, CHRYSO®, Strux®, SINTA® PP Fiber Series)

GCP maintains an independent market position, owning Adfil, CHRYSO, Strux and SINTA fiber brands. SINTA® is its well-known monofilament PP microfiber line for restraining plastic shrinkage cracks and lowering concrete permeability. Adfil® provides both micro and macro PP fiber solutions. Strux® macro PP fibers are engineered to replace welded wire mesh, improving residual flexural strength and impact resistance. CHRYSO integrates these fiber technologies into complete cementitious system solutions for precast, pavement and flooring projects. All GCP PP fiber grades meet global concrete fiber standards for commercial, residential and infrastructure construction.

Master Builders Solutions (MasterFiber®, Specter®, GENESIS® PP Series, MBCC Group)

Master Builders Solutions’ PP fiber lineup consists of MasterFiber®, Specter® and GENESIS® series, originally under MBCC Group (former BASF construction chemicals). MasterFiber® covers fibrillated and monofilament PP micro & macro fibers such as MasterFiber 012, 051 and 141, targeting early shrinkage crack inhibition and structural toughening. Specter® virgin homopolymer PP monofilament microfiber reduces plastic settlement and drying shrinkage cracking. GENESIS® high-performance PP macro fibers enhance ductility and fatigue resistance for slabs and precast components. In May 2023, Sika completed acquisition of MBCC Group. Master Builders Solutions fiber portfolio is progressively rebranded and integrated into Sika, while legacy MasterFiber, Specter and GENESIS products remain available during transition for existing project specifications.

Market Relationship Summary

Following Sika’s 2023 acquisition of MBCC Group, Sika and Master Builders Solutions now belong to the same corporate group; their overlapping PP fiber lines including SikaFiber, MasterFiber, Specter and GENESIS are undergoing product consolidation. GCP operates independently as Sika’s primary global competitor in construction PP fiber market, holding Adfil, CHRYSO, Strux and SINTA brands. All three enterprises produce 100% virgin polypropylene fiber for cement matrix reinforcement. Engineers and specifiers compare these series by fiber geometry, tensile property, mix compatibility, dosage and certification requirements for infrastructure and building projects.
