Concrete surfaces in contact with water

Increases the life expectancy of the concrete surface

For protecting the reinforcement

Sewage treatment plants, sewers and parts of power plants – all have one thing in common: a risk of conventional steel reinforcement corroding due to penetrating water.

Fibrofor High Grade reduces the water penetration depth into the concrete body by more than 25%; it reduces shrinkage cracks, and abrasion resistance increases. In this way, Fibrofor High Grade greatly improves the quality and service life of concrete parts exposed to water.

Sewage treatment plants and sewers are even more problematic, as they are often exposed to particularly aggressive liquids. Our synthetic fibres are proven to be resistant to such liquids.
Based on static evidence, the conventional steel reinforcement can be replaced to a large extent or even completely by Fibrofor High Grade or Concrix . In sewers, the combination of both fibres has proven to be particularly advantageous.

Moreover, when construction conditions are constricted, such as in underground structures, there is no need for the cumbersome insertion and laying of the structural steel, which means a significant reduction in construction time and costs thanks to our fibres.

If necessary, our engineers prepare a free, static calculation based on the latest standards.


Synthetic concrete fibres

The alternative to steel reinforcement and steel fibres for surfaces in contact with water.



Increased water penetration depth and durability of concrete surfaces.

  • Advantages

    Our synthetic fibres reduce maintenance costs

  • Water penetration depth

    Our products reduce the depth of water penetration into the concrete body. The fibres increase the quality and service life of components exposed to water.

  • Shrinkage behaviour

    In addition, they have a markedly positive influence on the shrinkage behaviour of components and extend the service life of structures.

  • Abrasion resistance

    Our products increase the resistance of the concrete surface to abrasion caused by vehicles, seawater or other uses. This lets you achieve a longer service life for structures that come into contact with water.
