- Metal reinforcement of concrete is not only heavy, hard to work with, prone to corrosion and requiring more concrete, it is also a massive risk for magnetic fields by its ability to attract stray current in the soil.

Another great product to help reduce our EMF exposures in building construction !!
I'm interested in the salesman.. he reminds me of a salesman I knew from New Zealand, he said its the perfect accent for sales... stays the same drunk or sober
Excellent to know. We'll be using it.
The steel reinforcement (rebar) is not attached to the building ground or neutral directly in the USA. The ground of house ( and neutral) is typically attached to a copper ground rod driven 8' into the ground and further bonded to a copper water pipe. That is it.
+1. Agreed. .. Shunt to Ground.
@@michaelschneider- We share a surname, but with a variant spelling.
I don’t think he was implying rebar is intentionally touching ground. Just the cases where it happens unintentionally. Either due to some the rebar sinking before the concrete is set, or via cracks in the concrete over time.
In the building of a swimming pool in the U.S., I believe the rebar is connected to a ground rod with a bonding wire (#8 bare copper) just as all the mechanical equipment for the pool is grounded to the same ground rod.
Hi Patrick. I’m planning to use Basalt mesh to reinforce a garden pot made in thin concrete. Basically it’s going to be a rectangle with a floor and feet. I can see how the mesh reinforces the faces, but at my corners, how can I use Basalt to go around the corners and maintain integrity? I could bend the mesh but unlike steel mesh does not hold its shape. How do I hold it in place? I could change from a sharp 90˚ bend to a radiused curved corner? I would prefer to avoid this. Thanks.
How does this hold up under the stresses of earthquakes? Does it have a crystalline structure prone to cracking?
Gave a like and shared. Question, is basalt rebar to counter magnets from pulling steel from concrete?
Show us the stress strain graph. Let's see the strain characteristics of it
Apparently the Canadians have a standard for its use that engineers use. We were told the Canadians like it as it gives their bridges longer life spans.
Best use that in salt land water
Germans used carbon fiber cloth and mesh in their concrete and they dot great results.
The higher the electrical conductivity, the more impervious to moving/changing magnetic fields. Silver, copper, gold, aluminum and on down the line in that order
The lack of understanding of these people is scary. It's literally having the opposite effect they are hoping for.
No. EMF = ElectroMagnetic Fields. Basalt fiber won't interfere with your cellphone signal.
And to think, that flexible rebar comes from lava, well done, great stuff. In an attempt to clarify, I wasn't clear what was meant in the title by "EMF proof". Since "Basalt fiber won't interfere with your cellphone signal", that simply means it isn't very electrically conductive. Ok, good. That's what I would expect of lava rock, basalt, way lower than the electrical conductivity of iron rebar. Simply talking Lenz's Law here. Iron is the 13th-most-conductive on the list at en.wikipedia.org/wiki/Electrical_resistivity_and_conductivity.
I think it's just a mistake in the title, I hope Patrick will see this and consider changing it. To me, "EMF proof" says ... impregnable to electromagnetic fields while reality is ... EMF pretty much won't even know the basalt is there basically as it passes through. But EMF are affected to some degree by iron rebar, just a little bit. Not because iron is paramagnetic but instead because it is electrically conductive. If your building has silver rebar (highest conductivity), first of all you live in Dubai, ha, and secondly at your desk in that building you have no cellphone reception. Kidding of course, silver would be far too expensive. Go with basalt.
I have a bit of passion on this topic because of a lot of experience and the public tends to be under a mistaken impression of how that all works but there's no reason for it to be so because it's really simple once you grasp it.
what is the name of this mans company
Would have been nice to get the company's name, seeing how they seem to claim to have a 100% basalt rebar and polymer basalt rebar.
Erin W. Hood thanks 🙏

Never knew weight had color.... white....
How has basalt reinforcement held up since this video was made? What does the result look like after a few years? Can the reinforcement cause the concrete to crack in locations with variations of temperature? I saw a graph somewhere showing how similar the thermal expansion is for concrete vs steel which is one of the reasons steel reinforcement is used. How does thermal expansion of basalt compare? Cheers.
It's very dangerous to use it as rebars. It will suddenly fully collapse without a warning. No time to repair the defect. Its a rock after-all, once it's cracked it just snaps into two parts, then the building collapse without a warning.

@@GoodGirl-wi5yo We want proof
@@GoodGirl-wi5yo"Its a rock after-all"
Nonsense. The aggregate in concrete is rock after all.
Hoping for more video and company name of the product basalt products
I wrote directly to a company in the U.S. that claims to sell this kind of rebar. I never heard anything back. I am not convinced a person can actually buy this kind of rebar. Maybe if you are a giant corporation, you can find it. As an individual looking to price it out, I found it is just not in the market and available. I hope your experience will differ.

How come we need any reinforcement in concrete when Romans built many concrete buildings without reinforcement which has lasted over 2000 years?
Becase not all concrete structures are under compression only. Under tension, concrete is not very strong.
Because the romans used a very light concrete mix, and yes they designed it all using arches to only use the concrete in compression. Fascinating! I guess we use unnecessary reinforcement when we could just change the shape and do as the romans did.
It’s not just the shape, it’s also the ability to build in a confined land area and with less material. And also (probably the biggest reason) is weather - the Romans didn’t have extremes of temperature or excessive rain. And there’s also access to volcanos too which not all parts of the world has. And it’s not as easy to apply because it’s much thicker than traditional concrete spraying equipment allows.
Which is a shame. The sooner we ditch steel reinforcement the better.
Patrick what is the name of the company
"Rockbar"
1:00 ever heard of electric wires? Yeah, they supply you with electricity, and they're in your wall, and they have >100x EMF than any metal rebar could ever have.
Non-metal rebars are not for "EMF proofing" but 3:00
Company's name and contacts please

Iron bars in concrete: When structure fails the whole structure will not collapse killing all the people inside that building. and we have time to repair the defect. As iron elongates or bends before full failure.
Basalt bars in concrete: You'll never know until it cracks and suddenly fully collapse. Never use basalt as bars. And never be in a building which has used basalt bars.
I have seen my share of rebar cement structures collapsing on TH-cam India
This comment was made by a person who has vast experience with one method.
You hear these types of comments made by "experts" throughout history whenever a new idea/ technology comes along.
What is true is that basalt rebar has ideal applications where steel utterly fails (i.e., in salt water environments for single-sory homes and businesses, as well as docks).
Beware when anyone uses superlatives such as "never" and "always." They lack vision and (more importantly) wisdom.
Cheers!
Could use a less inebriated-sounding spokesman.
Well, he does talk about alcohol resistance, so he needs the expertise ;)

Ah, engineering for the tinfoil hat folks.
I assure you, the rebar in my foundation, slab and below-grade walls are NOT grounded to the earth. The electrical system is, but not the metal in the concrete. When the opening salvo is crap. I don’t need the full sales pitch.
No need to knock what you don't know everything about and no need to be rude Mark. Metal in slabs was indeed not always grounded, in some countries that has only come in in the last few years. Some countries may not have made it a requirement.
@@geovitalacademy ah, but I do know, see. And I’d rather get slow-cooked, just a little each year, by EMF, over buying “the farm” in a slab failure all at once.
In your comment below you said basalt rebar causes slab failure. It could be the case you are just a fucking moron on a power trip because of how little you know.
Basalt Rebar doesn't rust. The steel Rebar in your foundation will rust. When it does it will expand and crack your concrete. Basalt becomes PART of the Concrete.
@@theebalz Basalt is rock. Concrete is mimicking rock. Not the right mix of performance under tension with performance under compression. We have decades and decades of experience with steel rebar performance in structures, and properly built, the performance is clearly stable, long-serving, and ethically engineerable. Basalt can never attain the tensile strength of steel, while steel can be kept stable in concrete for very extended periods.
Once you've built a foundation or three, you really see it in application. But hey, keep dreamin'.
