Product description
Wiking® Super B Fibres are made of 100% crushed basalt, a type of volcanic rock, which is found all around the world. To produce the fibres, basalt is melted at 1600 °C and then spun and extruded into very fine fibres.
Basalt is naturally resistant to external influences (such as alkalis, acids, extreme temperatures, water and rust), hence, no special coating of the fibres is needed.
Stronger than steel – light as a feather
Basalt is much stronger than steel and also 75% lighter than steel (in terms of density). This means that a smaller volume of basalt fibres is needed in comparison to using steel fibres.
Due to the exceptional strength of basalt, the fibres may allow for thinner and lighter concrete decks and panels. Depending on the construction, basalt fibres may even replace the need for steel mesh and steel bars. Hence, using Wiking® Super B may bring large cost savings to a construction project.
Improved concrete surface quality with basalt fibres
In contrast to steel fibres, basalt fibres do not appear at the surface of concrete, but will stay within the concrete mix. This leads to a more durable and aesthetically pleasing concrete surface.
Extending the duration of concrete and asphalt with basalt fibres
Importantly, basalt fibres can prevent the formation of plastic shrinkage cracks, as the fibres will cause the tensile strength to develop early in the drying/hardening phase. Also, basalt fibres will cause an increase of elasticity, making concrete and asphalt more resistant to impacts and bumps, for example those caused by heavy traffic.
Environmentally friendly and easy to dispose of
Basalt fibres are completely natural as they are made of crushed magmatic rock, which is found all around the Earth. This means that they are easy to dispose of. As an example, when a building is demolished, steel fibres and steel mesh need to be separated from concrete for disposal, whereas basalt can be disposed together with concrete.
Flexible solutions to your needs
Wiking® Super B fibres are available in various sizes to suit your concrete application. Please contact us for more information.
Frequently Asked Questions
Are all Wiking® Super B products flame-retardant?
Yes — basalt is a natural material that does not burn and is stable at high temperatures (see table).
Can basalt fibres replace steel?
Yes — Rebar is up to 3× stronger and 4× lighter than steel and does not corrode.
Which products are suitable for asphalt?
Wiking® Super B GeoGrid and Wiking® Super B Macro can be used in asphalt layers.
Can GeoGrid be used together with AS PE asphalt fibres?
Yes, GeoGrid can be used as a soil‑stabilising underlayer for asphalt work.
