Technical Info

• Basalt rebar can be placed to meet code requirements by using the calculations and installation guidelines for fiberglass reinforcement of concrete as defined in ACI 440.6-08. • No rusting allows basalt rebar to be placed with only 3/4” coverage of the rod and the surface of the concrete as per ACI440-6. This reduction in coverage requirements allows for more flexible designs potentially resulting in using less heavy and expensive concrete.

• Basalt rebar is the perfect reinforcement for today’s popular pervious concrete (low fines, 25% porous, water passing concrete). Pervious concrete reduces water retention or run off problems. Basalt rebar allows reinforcement with no fear of rust spalling (splitting). Since there is no rusting issue, basalt rebar may be placed within only 0.75” of surfaces where its tensile strength and high cycle tenacity can add stiffness without weight. Generally speaking, to add panel or beam stiffness it is recommended that more rods in small size be installed in critical structural designs as opposed to going with larger diameter reinforcement. The inherent design flexibility in adopting basalt rebar as non-rusting concrete reinforcement provides potential for many creative options.

• Basalt rebar is much lighter than steel rebar. One man can easily lift a 650’ coil or #2, #3 & #4. As a result, many jobs will no longer require hoists or forklifts to handle reinforcement. Workers comment they feel much less fatigue installing basalt as compared to steel. A 40’ piece of #5 steel rebar weighs over 41 pounds. Basalt rebar weighs about 12 pounds. Lighter weight to handle, basalt rebar is at least 2.2 times stronger than steel in tension.
