Composite mesh as a stronger, non-metal, lighter and healthier alternative to metal reinforcement of concrete
When we think of reinforced concrete, the thought of heavy metal mesh comes to mind as the hidden component within it, that gives concrete its tensile strength (the capacity of a material or structure to withstand loads tending to elongate). From a home health and radiation perspective, metal reinforcement of a slab posses a large potential problem which should be avoided when building.
Electric current can sometimes make its way into the soil. This can happen for example, when the neutral connection of a building’s electric system is compromised. The current that needs to leave the building uses it’s connection to ground to get out. If there is no metal water pipes, which would be a path of far less resistance for the returning current to travel by, the current will take the soil as means of getting back to the electrical supply system it came from.
This is a problem because the building loosing the current, no longer has even flow of current in its active/hot supply cable and the neutral cable that is the intended path for current to leave the building. The 2 flows of current produce a magnetic field that spins in opposite directions and when they meet, there is a cancelling-out effect. When the opposing flow is not there, there is no canceling out effect and a strong magnetic field exists.
The current lost to the soil poses the same problem, but in a different location. Whilst it travels though the soil it will always be attracted by the path of least resistance to get beck to its origin. If it meets a home with its usual copper ground stake poking in the soil, behind which a connection to that home’s neutral bar, and therefor a connection back to the power lines in the street… this will be an attractive path for the stray current. The unknowing and innocent home now gains current which upsets the balance between their the incoming and outgoing current and results in large ‘unexplainable’ magnetic fields.

Why is metal reinforcement potentially so bad for health?
A stake in the ground as means of grounding the electrical system of a home might be a nice little attractive path for stray current. A concrete slab with metal reinforcement within it, which is connected to the electric system’s ground, is an even easier to find and much large contact with the soil. This can, in case of stray current in the soil, function like an enormous vacuum cleaner relentlessly pulling stray current towards it. Upsetting the balance in flow of currents by great differences and pulling even larger magnetic fields into the home.
For those new to the subject of health being affected by low-level magnetic fields, here is a quick insight. The government exposure limit to magnetic fields is 1000mG (milligauss) or 100,000nT (nanotesla) in many countries. Here are just a few health affects found at lower levels:
Exposure | Health danger | Link |
---|---|---|
4mG or 400nT | Multiple research finds a link with childhood leukaemia being more prevalent at this level. | Here |
2mG or 200nT | Melatonin is blocked in its natural anti-cancer action. | Here |
1.6mG or 160nT | Doubling of the chances of sperm abnormalities. | Here |
1 to 2mG or 100 to 200nT | The mortality rate of children with leukaemia is found to be 260% higher than the control group not exposure to this level. This would seem to indicate a suppression of the immune system. | Here |
Non-Metal concrete reinforcement is so much better for so many reasons, including health
Alternatives to metal rebar are made from basalt rock fibre reinforced polymer (BFRP) or glass fibre reinforced polymer (GFRP). They are highly resistant to corrosion and therefor don’t let concrete rust or weaken. Perfect for use near water like sea walls and pools but it also means that the layer of concrete between the reinforcement and the soil can be thinner as much of that layer is there just to protect the normally used corroding metal reinforcement. A saving on concrete also means a large financial saving.
Not having metal in your concrete structure brings benefits also for health: The risk that the structure becomes un-resistible for stray current and their resulting magnetic fields that may develop, is a major benefit. Metal reinforcement can also be magnetic and avoiding another source of of static magnetic fields, just like we want to avoid it in mattresses, is another bonus.
The benefits of Basalt rock and Glass fibre rebar
Benefits of non-metal reinforcement of concrete |
---|
4 to 6 times lighter than metal equivalent |
Having the same diameter as metal mesh composite mesh can withstand tensile loads 3.5 times higher |
High corrosion and chemical resistance in severe environments |
Less concrete needed to ‘protect’ rebar because it doesn’t corrode |
Not critical that rebar is not in contact with the soil |
Regains its original shape after deformation |
Durability forecast more than 75 years |
Increased period without repair, reduced costs for maintenance |
Reduced labour cost as one person can carry the needed rebar onto site |
No potential interaction with stray current and resulting magnetic fields |
Not magnetic |
Legal requirements for using composite mesh instead of metal reinforcement
When a concrete slab is put in place for a home an engineer has to sign of on the design and construction of it. The engineer certifies that the structure complies with a code because the code protects him. There are codes available for the use of composite mesh as reinforcement in the USA, Canada and Europe.
When a suitable code does not exist in the country the home is build in, the engineer is often able to select another code which is suitable to use, even if it is from another country. Australia doesn’t have a code for this material yet for example (its being worked on) and so if you find yourself in a similar situation, it will pay to select your engineer based on their willingness to refer to overseas codes if non are available in your country.
Buy Basalt Rock or Glass Fibre concrete reinforcement
I am one of the, if not the busiest consultant globally, in the field of radiation-free building. My consulting services are available internationally and whilst on-site personal visits are certainly possible, much of my consulting is done over great distances with families all over the world. If needed, we may also be able to utilise the services of one of my consultants globally. I’d be delighted with your building project. The earlier the better, ideally even before you purchase the land you’ll be building on.
If you are interested how to buy this BFRP or GFRP mesh, just leave a comment below and I’ll email you the details.
In the meanwhile, you may also wish to attend my free webinar on radiation-free building. Check out our calendar to see when it is on next.
Hi I’m looking for either 5mmx5mm window openings basalt fibre mesh. Alternatively 10mm x 10mm can work if need be. Rolls I would like to have are 60″ wide. Alternatively 48″ , 39″ widths may work.
Looking for a version of the basalt that is superior to ot equal to 10oz AR glass fibre mesh.
Dear, Patrick
I’m looking for basalt rebar mesh that is composed of window(openning)size 100mm*100mm rebar thickness 2-3mm.width1000-1500mm, ang any length. Total quantity is about 1500m2.
If possible, please let me know the total cost to get to my door.
Thank you
Hello Patrick,
I want to contact you about future projects.
Best regads,
Mr.Petrov
Hello Patrick,
I am after a roll or two of basalt mesh (and if possible, also a small amount of basalt reo rod for a 6x6m slab trial). I am looking at a lightly earth-covered arch that is mostly in compression. Do you have any contacts for such small amounts of basalt mesh (and perhaps rebar) – I am in southern Tasmania, Australia. Was imagining 25x25mm mesh, in 1x50m rolls?
I also saw you had linked a talk on EMF radiation down here in 10 days – will have to check it out…!
Thanks greatly!
Sean.
Thanks Sean, I’ll email you the details.
HELLO, I AM LOOKING AT THE BASALT REINFORCING MESH FOR THIN CONCRETE PANEL WALL. I AM LOOKING AT 25 MM GRID. CAN YOU GIVE ME DETAILS AND COST STRUCTURE.
RUSSELL SMITH
Thanks for the inquiry Russell. I’ve emailed you the right contact to approach.
We are building a home out of shipping containers. The containers are already in place. Small parts of the connecting area need concrete floors. Please let us know the cost, dimensions and availability of BFPR and GFPR. I am also interested in the same info about paint. Any other consideration when building a home out of shipping containers from an EMF point of view ?
Thank you Martin. I’ll email you directly with the information.
Regarding shipping containers and EMFs: The metal already shields against radio frequency radiation (RF) so that is a bonus. I take it you’ll have some windows though, so placement of a high quality shielding fabric as curtaining is needed and you’re done with your RF shielding. Our NOVA is designed for the right reasons and the metal inside is protected against the effects of washing over time. (you don’t want your shielding to go down the drain).
Electricity inside the contained needs consideration as the whole contained can couple on the electric fields your wiring will likely produce. I can consult on that if so desired.
