What is RockRebar®

A Green, Renewable and Sustainable alternative to rusty steel rebar.

RockRebar® is 80% based on one component, NATURAL volcanic basalt rock. Basalt rock covers 70% of the earth’s surface, and unlike the manmade recipe for white fiberglass. Basalt rock converted into a “glass-state” basalt fiber does not
 require toxic chemicals to create it!
No contaminating waste is created from its production.
Structural basalt glass fiber is cost effective, naturally renewable and Eco-Friendly. In its production, basalt rock is crushed and loaded into a furnace where it’s melted at extreme temperatures. The molten rock is further processed by being drawn through platinum bushings. As the fibers are drawn from the bushings, they are stretched taut, increasing fiber strength as their diameter is reduce up to 90%. A proprietary “size” solidifies each of the continuous, “glass-state” basalt fibers at 17
millionths of a meter as they exit the process at:
Many Times The Tensile Strength Of Rusty Black Steel!
We take thousands of these continuous strands of Basalt fiber, coat them with our proprietary epoxy resin adhesive and pass this matrix thru a series of compression dies forming a cylinder-type shape. Before the final curing, a Dacron® strand is wrapped tightly around the fibers to cause a “squeezing” shape change that will ensure concrete will fill in forming a mechanical grip to RockRebar®. To further enhance grip with concrete, a coating of resilient crush resistant quartz sand is applied to the bundle as it begins to solidify by heat curing. The final result. RockRebar®, a time tested, industry recognized and totally non-rusting alternative for traditional steel reinforcement.

Why Use RockRebar®

The June 2016 official printing of AC-454 now allows for basalt fiber reinforced polymers (BFRP) to be used in the reinforcement of concrete. Additionally, States are also mandated to consider “life cycle” costs of all future road and bridge products as written in the Moving Ahead for Progress in the 21st Century Act (MAP 21) passed on July 6, 2012.

Due to the fact that Basalt products never rust, we believe RockRebar® will meet the mandated requirements, vastly reducing the need to redo infrastructure and obtain very little maintenance costs over time. 

With its durability, strength and longevity, basalt has no true rival; it will no doubt be the last rock standing.

NEVER RUSTS

RockRebar® can not rust, ever! The most important solution to modern construction technology and to preventative maintenance due to expensive repairs.

LESS WEIGHT

RockRebar® is only 1/4th the weight and over 2.5 times stronger than traditional steel rebar. Creating savings on shipping costs and labor, as well as safety on handling.

STRONGER MATERIAL

RockRebar® is an alternative to steel and fiberglass concrete reinforcement. Made from volcanic rock, basalt rebar is stronger than steel and has a higher tensile strength (2.5 times STRONGER).

NATURALLY RESISTANT

RockRebar® is naturally resistant to alkali, rust and acids. Moisture penetration into concrete does not cause spall. Needs no special coating like steel or fiberglass rods.

MARINE FRIENDLY

RockRebar® is perfect for marine environments and chemical plants where corrosion is a continuous problem. They are the only products in the marketplace that address “alkaline” and “PH”, allowing them to be used with salt water.

CONSTRUCTION SAVINGS

RockRebar® does not require expensive heavy lifting cranes on job sites, creating additional savings and easy to handle in remote construction sites where road access might be limited.

RADIO FREQUENCY TRANSPARENT

RockRebar® is transparent to radio frequency unlike that of steel.

STABLE CONDITIONS

RockRebar® is non-magnetic, non-conductive & UV stable, as well as excellent in high voltage areas.

LONG LIFE CYCLE

RockRebar® non-corrosive nature makes it extremely valuable in terms of lifecycle requiring far less replacments necessary and broadly applicable to the entire construction industry.

Why RockRebar® is a Superior FRP​

RockRebar® ( BFRP / Basalt rebar) is a product that when tested, proved to be only 1/4th the weight of steel, yet proved to have a higher tensile strength than traditional steel rebar. The June 2016 official printing of AC-454 now labels continuous basalt fiber and a special manmade fiberglass E-CR (corrosion resistant) fiberglass as sufficiently similar in overall performance as to be interchangeable for use in producing FRP concrete reinforcements. Brown basalt fiber reinforced polymer BFRP rebar and the white fiberglass GFRP rebar are now the only two “glass state” structural fibers officially recognized for concrete reinforcement. Naturally, occurring basalt has several advantages.

With only a single component required to produce continuous basalt fiber, the quarry process to collect basalt rock requires less of a carbon footprint in comparison to mining a dozen minerals to produce man-made white silica based E-CR fiberglass. ​ Boron, a potentially toxic trace mineral, is present in white fiberglass. However, at the base fiber level, basalt is non-toxic and naturally boron-free. Basalt rock is naturally boron free and clearly basalt is time proven to remain “rock solid”, standing today when all other minerals have long since eroded away.
