Our new product is taking the market by storm: the polyamide fibre for modern fibre-reinforced concrete
We have reimagined polyamide fibres and, in collaboration with the Institute for Building Research at RWTH Aachen (ibac) developed a new product. The result is ENNEAFIL – ‘the high-strength fibre’ with outstanding mechanical properties and a wide range of applications in concrete processing.
The use of ENNEAFIL significantly reduces cracking, minimises shrinkage and, in some cases, replaces or reduces the need for steel reinforcement. With ENNEAFIL, we have laid the foundation for innovation.
The right material for every requirement profile: whilst robust polypropylene (PP) in the high-performance lengths of 54 mm and 65 mm has proven itself worldwide in the field of structurally effective macro-fibres, we specifically rely on high-strength polyamide (PA) for our ENNEAFIL micro-fibres. This specific choice of material guarantees excellent tensile strength in the field of micro-reinforcement and optimal anchoring within the cement matrix, preventing the finest cracks in fibre-reinforced concrete right from the start.
If you wish to reinforce concrete with fibres, ENNEAFIL offers a highly efficient alternative to steel reinforcement for your construction project.
«ENNEAFIL is an innovative polyamide fibre used as a concrete additive.
It enables a new, particularly energy-efficient way of building, offering numerous benefits.»

Benefits of weight reduction: Maximum stability & improved carbon footprint
Concrete containing ENNEAFIL is both ultra-light and highly stable – this makes it possible, for example, to add storeys to existing buildings without compromising their structural integrity. Steel reinforcement can be dispensed with either entirely or in part. Enneafil reduces CO₂ emissions by a significant amount that would otherwise be generated during steel production. Corrosion and weight-related issues associated with reinforced concrete, as well as cracking and shrinkage of the concrete, can be significantly reduced. Furthermore, this opens up entirely new possibilities for the use of precast concrete elements, as more can be prefabricated at the factory – thereby reducing transport times, transport costs and transport emissions.

Advantages of ENNEAFIL polyamide fibre
FEATURES & BENEFITS
ENNEAFIL offers optimised mechanical properties as a plastic fibre for concrete
Our high-strength plastic fibre systems for concrete can reduce or completely replace conventional steel reinforcement. Whilst our Macro fibres bear the structural loads, the ENNEAFIL Micro fibres ensure highly efficient minimisation of shrinkage cracks. They significantly reduce both cracking and shrinkage behaviour in fibre-reinforced concrete. The material is also non-conductive, completely corrosion-free and offers architects delicate structures with maximum design freedom.
COSTS & COST-EFFECTIVENESS
ENNEAFIL reduces overall costs compared with traditional concrete reinforcement
The overall costs when using ENNEAFIL are already lower than those associated with conventional concrete reinforcement made from structural steel. When you purchase our high-strength concrete fibres, you make savings in several ways: as the material is completely corrosion-free, there is no need for the concrete protective layer that would otherwise be required. This allows for significantly thinner walls to be constructed, saving valuable quantities of material and ensuring that the cost of the concrete fibres is quickly recouped. The improved insulation also reduces energy consumption, whilst the extremely long service life minimises the need for future repairs.
SUSTAINABILITY & CARBON FOOTPRINT
With ENNEAFIL, you can build sustainably and with an eye to the future
Our ENNEAFIL polyamide fibres are produced using 100% renewable energy. In practical applications, this innovative plastic fibre for concrete improves thermal insulation properties and significantly increases the energy efficiency of buildings. Thanks to the extremely high durability of our concrete fibre, the structure achieves a significantly longer service life than in traditional mass concrete construction. Should the structure nevertheless be demolished after several generations, the entire fibre-reinforced concrete can be fully reused without any problems.

ENNEAFIL Microfibres
ENNEAFIL
Micro- & Macrofibres
Our fibre system offers the ideal solution for every phase of a project: the thin ENNEAFIL micro-fibres made of polyamide are distributed three-dimensionally within the concrete. Thanks to their hydrophilic properties, they regulate moisture levels during the drying and curing phases, thereby effectively preventing shrinkage and cracking. In addition, our robust polypropylene (PP) macro-fibres take on the structural load-bearing functions in the hardened concrete and serve as a highly efficient, corrosion-free alternative to steel.

A comparison of concrete reinforcement: Why ENNEAFIL stands out
Our ENNEAFIL microfibres offer outstanding mechanical properties and are more sustainable and cost-effective. Compared with conventional materials used for concrete reinforcement, such as steel, carbon fibre, basalt fibre and glass fibre, ENNEAFIL – whilst offering optimised mechanical properties – is superior in two respects:
- Low total cost
- Sustainability
| Material | Properties | Costs | Sustainability |
|---|---|---|---|

Frequently Asked Questions (FAQ)
ENNEAFIL
ENNEAFIL concrete fibres are high-performance fibres used as an additive in concrete. They improve the mechanical properties of the concrete, reduce cracking and increase durability. These fibres offer a cost-effective solution for optimising concrete mixes and are used in a variety of construction applications. They are ideal for applications such as shotcrete and screed.
ENNEAFIL concrete fibres reduce cracking and improve the impact resistance of concrete. They are corrosion-free, chemically resistant and extend the service life of the concrete. Their uniform distribution within the concrete ensures improved strength and stability. They improve workability and reduce weight compared with conventional steel reinforcement.
ENNEAFIL microfibres are available in lengths of 6 mm, 12 mm and 18 mm. For more demanding applications, ENNEAFIL macrofibres are available in lengths of 54 mm and 65 mm. This range allows for optimal adaptation to the specific requirements of each construction project.
- 6 mm microfibres: For thin screeds and rendering mortar.
- 12 mm and 18 mm microfibres: For general concrete mixes and shotcrete, where good distribution and crack reduction are required.
- 40–60 mm macro-fibres: For larger, heavily loaded concrete structures such as floor slabs, foundation slabs and traffic surfaces, to enhance structural integrity and to replace or reduce steel reinforcement.
ENNEAFIL concrete fibres are used in floor slabs, industrial floors, traffic areas, ceilings, floors for animal housing, electric vehicle charging points, precast concrete elements and walls. They are particularly useful in areas where high demands are placed on the crack resistance and durability of the concrete.
The polyamide and polypropylene fibres are distributed evenly throughout the concrete and absorb moisture, which they then release again during the drying and curing phases. This significantly reduces cracking and shrinkage. The fibres reinforce the concrete matrix, improve its toughness and reduce the risk of stress cracks.
ENNEAFIL concrete fibres hold various certificates, including the Carbon Footprint Certificate and the EFB Certificate. There are also general building authority approvals and detailed data sheets for micro- and macro-fibres, which describe all technical specifications and possible applications.
ENNEAFIL Macro concrete fibres are made from 100% pure polypropylene, which is known for its high mechanical and chemical resistance. This plastic ensures that the fibres offer a long service life and high performance within the concrete.
ENNEAFIL concrete fibres improve the thermal insulation properties of lightweight concrete, which reduces the heating and cooling requirements of buildings. This contributes to energy efficiency and lowers operating costs. The increased durability and reduced cracking also reduce the energy required for repairs and maintenance.
ENNEAFIL concrete fibres can partially replace or reduce the use of steel reinforcement, thereby reducing CO₂ emissions from steel production. They also help to extend the service life of structures, thereby reducing the need for frequent repairs and new builds, which also cuts CO₂ emissions.
ENNEATECH’s primary sustainability objectives include promoting sustainable consumption and production, reducing CO₂ emissions and utilising clean energy sources.
