Basalt FRP rebar represents non-metallic reinforcement rods of various actual lengths and outer diameter with dimensions from 4 to 32 mm. Basalt FRP rebar is produced by the method of pultrusion and epoxy resin. Due to unique performance properties, it is an efficient and cost effective alternative to steel reinforcement.
Our production method allows to compete in cost to steel rebar when taken into account equal strength replacement.
It is not proposed that basalt should replace steel in its entirety. Its application is for a specific use where there is a danger that normal steel bar may be compromised by close proximity of chemicals, acid and alkaline.
Most especially in maritime environments i.e. sea wall defences, transport infrastructure roads and bridges it will replace the necessity to utilise epoxy coated or galvanised rebar, neither options being absolutely fail safe, or stainless steel which is even more expensive than basalt rebar.
Basalt rebar is affording greater longevity in structures that incorporate it.

The construction mesh is made of basalt roving with acrylic impregnation and polyester thread. It is an effective and economically advantageous substitute to ta traditional steel mesh due to its strength, low thermal conductivity and long-term retention of its qualities in aggressive environment, loads and temperature changes. Basalt mesh can also be used in construction of industrial and civil buildings in seismic regions.
Depending on the application, the mesh can have different density and cell size.

Basalt geogrid is designed for reinforcing road surface. It is successfully used in construction, repair and reconstruction of roads as a reinforcing layer. The main function of the material is uniform distribution of external load on the road over the entire surface, removal of internal stress of the asphalt-concrete coating, and also increase in the strength of the finishing layer of the asphalt to break.
Benefits:
The geogrid has different areas of application. For example, it is possible to use the geogrid for both soil and asphalt concrete.
The basalt geogrid used for asphalt concrete strengthens the layers of construction materials, thus prolonging the operational period of the surface, and also stops appearance of cracks and gaps in joints.
Saving on building materials by using the geogrid reaches 35%. This is achieved by the special structure and properties of the materials used. And, importantly, the original structure of the construct remains which, moreover, becomes even stronger.

Basalt fibre is made by chopping continuous basalt fiblre into short lengths. Basalt fibre used as reinforcing agent for concrete, plaster and plastics, providing three-dimensional strengthening. To achiene better adhesion, uniform distributiona nd maximum reinforcing effect, depending on application area, it is necessary to selecta relevant monofilament diameter, cut length, moisture content, and sizing.
Basalt fibre is a unique material for the manufacture of porous, foamed and aerated concretes, for adding into dry construction mixes to increase their plasticity, water-resistant and adhesive properties.

| Cut length, mm | from 6 to 72 |
| Temperature range, C | from -260 up to +700 |
| Hydroscopisity, % | not mor than 0,2 |
| Resistance to acids and alcalis | high |
| Moisture content, % water | for concrete: 6-10 for production: 0,5 - 0,8 |
| Sizing | Water compatible for concrete* Water incompatible for production |
| Packaging | PE bags 10, 20, 25kg; jumbo bags 250 and 500 kg |
* fibre for concrete without sizing is available.
Basalt fibre reinforcement adds:
Basalt fibre provides high adhesion to concrete ( «stone-stone») without deterioration of the reinforcing properties over time; it is a corrosion resistant material that does not get inflamed even exposed to open fire, it does not bunch up when added at any time of making and pouring the mix. Basalt fibre can be used for concretes with plasticizers and agents that change the setting time. Reduces cement and water consumption.
Due to excellent durability, basalt fibre is highly suitable for reinforcing concrete used when strength requirements are especially high: floors, grounds, roads with heavy traffic of people or transport. High resistance to climatic factors and hygroscopic properties make basalt fibre essential for hydraulic structures and coast protection. Basalt fibre reinforced concrete finds its application in building earthquake-proof structures, explosion hazardous facilities, reservoirs and concrete pipes used for transporting aggressive substances and liquids with great number of abrasive particles, and nuclear and chemical facilities.
Basalt fibre is a unique material for the manufacture of porous, foamed and aerated concretes, for adding into dry construction mixes to increase their plasticity, water-resistant and adhesive properties.
Dry fibre with water incompatible sizing is used for the manufacture of brake pads and needle-punched mats.
