Our Commitment

Revolutionizing the Construction Industry with Basalt Fiber

At BasaltechSA, we are dedicated to revolutionizing the construction industry by offering sustainable and environmentally friendly solutions. Our focus on Basalt Fiber allows us to provide innovative and reliable materials for commercial, infrastructure, and residential projects.

Our Vision

We envision a world where all future construction is harmless to our planet, health, and resources — an industry that embraces Basalt Fiber as the sustainable, eco-friendly standard, dedicated to reducing its carbon footprint for generations to come.

Our Mission

To lead in the supply and distribution of innovative, high-quality Basalt Fiber Reinforced Polymer products, championing technological advancements and eco-friendly construction materials.

Raise awareness about the importance of incorporating environmentally friendly alternatives in concrete and asphalt reinforcement projects.

Provide durable, sustainable solutions that significantly reduce the construction industry's carbon footprint.

BasaltechSA Products

Two Products, Engineered for Infrastructure

High-strength basalt fibre for concrete and composites, and basalt reinforcing mesh for roads and surfaces. Both are corrosion-proof, lightweight, and backed by research and testing — built to be specified with confidence.

BasaltechSA basalt fibre for concrete reinforcement
Concrete & Composite Reinforcement

BasaltechSA Basalt Fibre

A high-performance reinforcing fibre spun from molten volcanic rock. Added to concrete, mortar and asphalt — or supplied as BFRP rebar — it lifts tensile and flexural capacity, restrains cracking, and never corrodes.

Filament tensile strength of 3,000–4,840 MPa — several times that of steel at fibre level
As BFRP rebar, roughly 2–2.5× the tensile strength of steel rebar, with zero corrosion
Improves flexural strength and restrains micro-cracking in concrete through fibre bridging
Stable from −260 °C to ~700 °C; immune to alkali, acid and chloride attack
Specifiable to ASTM D8505, ACI 440 and ISO 10406

BasaltechSA basalt reinforcing mesh and geogrid
Pavement & Surface Reinforcement

BasaltechSA Reinforcing Mesh

An alkali-resistant basalt geogrid for asphalt and concrete. It spreads traffic loads, relieves stress and controls reflective cracking — extending pavement life at a fraction of the weight of steel mesh.

Factory-tested at ~110 kN/m (machine direction) and up to 120 kN/m across — above typical commercial basalt geogrid
Cuts reflective cracking and improves the fatigue life of asphalt overlays (peer-reviewed)
Alkali- and corrosion-resistant — won’t rust like steel mesh
Lightweight and easy to lay — no special equipment required
Holds strength through paving and in-service temperatures

Product Properties

Why Basalt Fiber Outperforms the Rest

Derived from volcanic rock, basalt fiber offers remarkable resilience — far outperforming traditional materials across every key property.

Mechanical strength properties

Mechanical Properties

Basalt fiber weighs only 25% of steel reinforcement but offers 2.5× the specific tensile strength, and 20–40% better mechanical strength and puncture resistance than glass fiber.

Eco-friendly fiber production

Environmentally Friendly

A natural, sustainable material with an energy-efficient production process. Basalt fiber has a 74% smaller carbon footprint than steel and reduces CO₂ emissions by 5.24 tons of coal equivalent per ton produced.

Thermal stability of basalt fiber

Thermal Properties

Basalt fiber withstands temperatures from −260°C to 700°C, maintaining complete structural integrity in extreme cold and heat — ideal for asphalt and concrete paving applications.

Corrosion resistance

Corrosion Resistance

Unlike steel, basalt fiber is completely impervious to rust and corrosion. It performs exceptionally well in harsh organic, inorganic, acidic, or alkaline environments — significantly extending the lifespan of structures.

corrosion resistance rating
Fatigue resistance under stress

Fatigue Resistance

Basalt fiber exhibits superior fatigue resistance, ensuring sustained performance under repetitive stress and reducing the risk of failure in high-stress environments such as roads, bridges, and industrial floors.

Electromagnetic neutrality

Electromagnetic Neutrality

Basalt fiber’s excellent dielectric properties make it ideal for applications requiring electromagnetic neutrality — including telecoms infrastructure, aerospace facilities, and medical buildings.

How basalt compares to the materials you already know, the strength numbers behind it, real factory test results, and the standards you can write straight into your designs.

BFRP rebar vs steel rebar (tensile)

One basalt bar does the job of a steel one — higher strength, and it never rusts.

How much it flexes under load — stiffer than glass fibre, more flexible than steel.

Density vs steel — 2.6–2.8 vs 7.85 g/cm³

A third of steel’s weight — cheaper to ship and quicker to install.

Tensile Test Results

Single strand5.571 kN
Machine direction (per 1 m width)109.64 kN/m
Cross directionup to 120 kN/m

Machine direction = 19.68 strands × 5.571 kN per metre width. Product is manufactured above export requirements with a built-in safety margin; recorded values can be reduced by strand slippage in winding-type test fixtures. For context, typical commercial basalt geogrids test at 50–100 kN/m.
