Basalt Rebar – the alternative to steel and fiberglass

Basalt rebar reinforcement is an alternative to steel and fiberglass for reinforcing concrete. Made from volcanic rock, basalt rebar is tougher and stronger than steel with a higher tensile strength.

Basalt rebar is much lighter than steel rebar making it easier to work with and so much cheaper to ship!

Basalt rebar is naturally resistant to alkali, rust and acids. Moisture penetration from concrete does not spall. Needs no special coating like fiberglass rods.

Basalt rebar has the same thermal coefficient expansion as concrete!

Allowing thinner, lighter panels and decks, basalt rebar reduces the thickness and spacing between the rods and the concrete and surface. Much more flexible design! Smaller rods allow for more critical spacing and designs.

Basalt rebar is easily cut to length with regular tools.

Basalt rebar does not conduct electricity or induce fields when exposed to RF energy, great for MRI or data buildings.

Basalt rebar reinforcement is perfect for Marine environments and Chemical plants where corrosion is a continuous concern.

Check out this swimming pool construction with basalt rebar. Also used in archeological sites with natural hydraulic lime, and a bridge entirely reinforced with composite materials. See on our blog more projects using basalt rebar reinforcement.


Basalt Rebar is available in the following diameters: 4mm. 6mm. 8mm. 10mm. 12mm. 25mm. 4mm to 12mm available in 100m coils or cut lengths. 14mm to 25mm packaged in 10 foot cut lengths. Contact Nick for more information, basalt product prices and shipping quotes.
