What is basalt fiber?

Basalt fiber is widely used in civil and industrial construction, infrastructure facilities, especially where the structures are exposed to heavy mechanical, chemical, thermal and other aggressive impacts.

Basalt Fiber is extremely resistant to mechanical abrasion, water and chemicals, so fiber reinforced concretes are widely used for floors, grounds, roads with heavy traffic of people or vehicles.

Basalt fiber reinforced concretes are used to build earthquake-proof structures, fortifications, explosion hazardous facilities, reservoirs and concrete pipes to transport aggressive substances and liquids with high content of abrasive particles.


  • Monofilament diameter – from 13 up to 30 micron.
  • Cut length – from 6 up to 72 mm
  • Sizing – water-soluble, content from 0,04%
  • Temperature range – from -260C up to + 700C
  • Resistant to acids and alkalis
  • Hygroscopic material
  • Dielectric
  • Consumption – 0.5 – 5 kg/m3

Frequently asked questions

Continuous basalt fiber is made by melting igneous basalt rock. It is an environmentally friendly material because no chemical additives are used to manufacture basalt fiber. It has high strength, resistance to aggressive environments, temperature stability, low electrical conductivity, and hygroscopic properties.

Savings in the construction process occurs when diameters are replaced with smaller ones according to the strength properties (tensile strength of basalt composites is higher than that of metal), lower cost of transportation and unloading, as well as optimization of assembling due to the light weight. In addition, basalt rebar does not corrode or conduct heat, it has hygroscopic properties and therefore basalt rebar reinforced concrete structures are more durable.

Basalt fiber as a reinforcing material is perfectly suited for road construction and repair, namely reinforcement of asphalt concrete and strengthening the road beds with basalt fiber and basalt grid, providing strength and durability for the roadway.
