The easiest way to avoid cracks

Meraflex microfibres in your concrete mix will minimise the risk of cracks due to shrinkage, improve the resistance and the appearance of your concrete structures. In addition, Meraflex is very easy to work with. The fibres will uniformly distribute across the concrete mix and therefore offer a homogenous distribution of stress across your concrete structure.

Your benefits

  • Minimizes cracks
  • Improves fire resistance
  • Easy to work with
  • Uniform distribution into the concrete mix
  • Improves abrasion and impact resistance
  • Improves surface appearance
  • Protects against chemical or atmospheric agents

The surest protection against fires

Fires can cause cracks and weaken your concrete construction. By adding Meraflex PP microfibres, you can avoid spallation due to fires. During a fire, the Meraflex fibre will melt at 160°C and create porosity. As a result, the generated steam can be evacuated. This will reduce the pressure in your construction and avoid spalling.

IBS (Institut für Brandschutztechnik und Sicherheitsforschung Gesellschaft) has tested the Meraflex PP microfibres according the ÖBV guideline for "Increased structural fire protection for underground traffic structures made of concrete".

Applications

  • Tunneling
  • Concrete reinforcement
  • Precast concrete
  • Commercial & residential slabs
