About Us

Basalt Engineering LLC, a manufacturing company based in Winchester Virginia, produces a range of downstream products from Continuous Basalt Fiber (CBF) for the construction industry. Our flagship product is Bastech® Basalt Fiber Reinforced Polymer (BFRP) Rebar.

We manufacture bar sizes #2 to #8 in standard and custom lengths. #2 and #3 can manufactured in 300 ft. coils.

Our products have been evaluated by ICC-ES.  See ICC-ES Evaluation Report No. ESR-4648

Basalt Rock

Basalt is igneous rock formed from the rapid cooling of basaltic lava exposed at or very near the surface of the earths crust. The fiber is produced in a single process needing no alterations or elemental additives. The process consists only of melting ingenious rock containing a specific mineral content found in a few specific areas. Basalt Fiber, unlike Glass Fiber, is a one component fiber that does not need any other materials added for production. ,

Basalt Fiber

In the production of BASTECH® rebar two components are used: Continuous Basalt Fiber (CBF) and inert resin. CBF is a product of a single step extraction from molten basaltic rock without the use of any chemicals. Basalt Rock is a single-component resource of natural origin and is an ecologically clean raw material.

Basalt fiber will eventually replace both expensive carbon fiber products and those of ecologically harmful glass fiber

Stronger | Lighter | Non-Corrosive | Environmentally Friendly


The process of manufacturing requires pultrusion of basalt roving mixed with resin through production line. The production lines are built to our specifications and proprietary. The manufactured basalt rebar complies with AC454, ASTM and FDOT requirements.


BASTECH® Basalt rebar represents non-metallic concrete reinforcement rods of various lengths and standard diameters which currently include #2, #3, #4, #5, #6, #7, #8 – bar size 1/4” (6mm) to 1” (25mm) diameter.  Due to unique performance properties, it is an efficient and cost effective alternative to steel reinforcement.  We can also manufacture both custom diameters and lengths for customers with specific uses, for example, in manufacturing precast concrete products.

Main advantages of BASTECH® Basalt Rebar:

  • 2.5 times stronger than steel
  • 5 times lighter than steel
  • Basalt rebar is naturally resistant to alkali, rust and acids.
  • Moisture penetration from concrete does not spall.
  • Needs no special coating like glass fiber rods.
  • Basalt rebar has the same thermal coefficient expansion as concrete.
  • 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 hospital or datacenter buildings.
  • On average 60% less COemission in final concrete structures due to production process, logistics and material optimization.
  • Overall project cost is less than with steel rebar.
  • Up to 50% labor savings on handling and installation versus steel rebar.
