r grip

r-grip is a high-performance synthetic macrofiber made from a polyolefin blend. It is specifically designed for the structural reinforcement of concrete and is characterized by its embossed surface, which ensures superior mechanical anchorage within the cement matrix.

The fundamental difference is the material. Being 100% polymeric, r-grip offers unique advantages:

• Zero Corrosion: It is completely immune to rust and chemical attacks, making it ideal for aggressive environments.
• Extremely Lightweight: It is approximately 7 times lighter than steel, which greatly facilitates handling, dosing, and reduces logistics costs.
• Maximum Safety: It eliminates the risk of tire punctures for machinery and cuts for workers.
• Low Carbon Footprint: Its production process is significantly less energy-intensive than that of steel, resulting in a more sustainable reinforcement solution.

It is the perfect solution for projects where durability and exposure to external agents are critical:

• Marine Environments: Ports, promenades, docks, and any structure in contact with saltwater.
• Chemical or Industrial Plants: Slabs and elements exposed to aggressive chemical spills.
• Pavements with Aesthetic Requirements: Where the appearance of rust stains on the surface is unacceptable.
• Precast Elements: Lightweight panels and components that require durable, non-corrosive reinforcement.

The anchorage of r-grip is based on its embossed surface. This continuous pattern creates a mechanical micro-interlock along the entire length of the fiber. When the concrete cracks, this texture prevents the fiber from pulling out, allowing for effective load transfer across the crack and providing necessary ductility.

Yes. r-grip is a Class II structural fiber according to the EN 14889-2 standard, which certifies its ability to provide residual strength to concrete. Through engineering design, it can replace steel mesh for shrinkage crack control and to bear structural loads, offering ductile post-crack behavior.

As with steel fibers, the dosage is the result of a specific calculation for each project. However, due to its low density, the dosages in kilograms per cubic meter (kg/m³) are much lower than those for steel to achieve comparable performance. Typical dosages usually range from 2 to 7 kg/m³ (approx. 3.4-11.8 lb/yd³).

Yes. Polymeric fibers like r-grip are very flexible and lightweight, which facilitates mixing and pumping. They disperse very homogeneously within the concrete mass without forming "hedge
