Why use basalt rebar vs steel rebar for reinforcing concrete?

Perhaps the greatest threat to the long-term durability of reinforced concrete is corrosion of the steel (primarily composed of iron, or Fe) which expands due to the greater volume of the corrosion byproducts and then cracks the concrete and debonds from the concrete matrix. Billions of dollars in damage occurs each year due to this simple reaction, and our apparent inability to stop it. So what causes this reaction?



Spalling as it is called, pops large chunks of concrete apart. Especially near salt water, corrosion of steel and Portland cement is obvious and visible everywhere. Basalt fibers and reinforcements are the solution!

Better concretes and additives. Volcanic rock fiber reinforcement basalt rebarsbasalt meshes and basalt chopped fibers. These are materials which will never corrode and help prevent cracking of the cement from the start. Once water gets in it is the beginning of the end.


Extensive (and expensive) repairs can be prevented by building with the correct materials from the start. In this case, using basalt rebar instead of steel rebar, the concrete wall would have a much longer lifespan, saving money, materials, time and labor. Plus, avoiding a potentially dangerous situation in a heavily trafficked public location.

Using Carbon Fiber for Structural Foundation Repair

There have been many changes and advancements in home construction materials over the years.The materials we use to repair our homes have changed, too.  Spray foam fills voids around windows instead of bits of Fiberglas insulation.  Fast-drying, lightweight spackle makes filling holes in walls a quick and easy job.  Water-based paints have all but replaced oils, especially for do-it-yourselfers.You can buy DIY carbon fiber wall repair kit – FiberPatch online here 

Changes have come to professional home repairs too, including the use of carbon fiber strips for structural foundation repairs.


Using Carbon Fiber for Structural Foundation Repair

The old way of repairing a wall that had bulged, bowed or rotated inward due to lateral pressure from expanding soil around a home’s foundation was to use steel I-beams set vertically against the inside of the wall and anchored top and bottom to prevent further movement.  This method is still used occasionally but has been largely supplanted by other methods, mostly by applying carbon fiber strips.

Carbon fiber is a high-strength strand that is woven into a fabric that is virtually unbreakable and does not stretch.  When used for structural foundation repair, it is epoxied to the damaged wall at intervals determined by the type and severity of the damage.  When a steel angle is added to the top of the wall, between floor joists, the wall is completely stabilized and no further movement occurs.


The Pros of Carbon Fiber for Foundation Repair

Quick Installation – The installation process for carbon fiber is very simple:  the area of the wall where the strip will go is ground flat and a bed of high-strength epoxy is applied.  The carbon fiber strip is embedded into this under pressure and the steel angle is bolted to the top.  Depending on the size of the wall, carbon fiber repairs can be done in a day.

Incredible Strength – Carbon fiber is a super strong material that is even being used in the construction of commercial aircraft.  It cannot break and the fibers do not stretch so when properly applied the wall repairs are permanent.

Low Visibility — When the carbon fiber strip has been applied to the wall, it shows up as only a small bump on the wall, a fraction of an inch thick.  It can be painted over, which makes it nearly disappear, and a normal stud wall can be constructed over it if the basement is to be finished.


No Maintenance – When the carbon fiber repair is finished, it requires no further attention from the homeowner – or anyone.

Low Cost – Carbon fiber repairs can be done for approximately half the cost of steel beams.

Carbon Fiber: Only One Drawback

Limits on Application – The only drawback to carbon fiber repair is that it can be used only on walls that have deflected, or moved inward, two inches or less.  When it comes to wall movement, two inches is quite a lot, so most homeowners will have noticed the problem before that point.  Given all the advantages of carbon fiber repairs, there are good reasons for homeowners to pay close attention to any signs of foundation wall damage.

In cases of extreme wall movement, steel is used but the process has been updated to create repairs that require no maintenance and may be less obtrusive than in the past.

Although the carbon fiber process is not overly complex, it requires the services of a professional who understands the nature of the damage and can specify the proper number and location of carbon fiber strips, as well as installers who do the work properly.
