Imagine: You’re finally home after a long day at work. After unlocking your front door, you instinctively turn on the lights and fall to your plush, comfy couch with a big sigh. You worked hard today. But now you’re home, and you’re warm and watching TV to relax. And chances are, you haven’t thought, for even a second, about what it took to provide your home with the light, heat, or electricity that you now enjoy with your family. But for approximately 83,000 coal miners in the United States, who risk their lives every day to provide us with the energy that allows us to maintain our comfortable, digital lifestyles, the source of that energy is as precious as life itself. Coal miners face death and injury every single day, and many never return to their own warm homes and comfy, plush couches.
“A miner’s life is like a sailor, aboard a ship to cross the waves;
Every day his life’s in danger, still he ventures, being brave;
Unlike you or me, a miner goes to work every day
Knowing that he is placing his life in grave danger.”
(Verse from an old mining song)
For more than 100 years, coal miners have been the backbone of West Virginia’s economy. And considering that West Virginia is the heart of America’s coal mining industry, it’s safe to say that coal miners have played a huge role in the overall economic success of our beloved country as well. In fact, without the selfless dedication of our miners, American society wouldn’t have flourished as it has, nor would it continue to function as it does. In consideration of the sacrifices that American miners have made for the overall good of the public, National Miner’s Day seeks to “honor each and every miner; past, present, and future.”
December, 1907 is known in the coal fields as “Bloody December.” On December 1st of that year, a gas explosion killed 34 miners in Fayette City, PA. Only five days later, on December 6th, the worst industrial accident in American history killed 361 in the tragic West Virginia Monongah mine disaster. 10 days later, an explosion in Yolande, Alabama killed another 57 miners, and on December 19th, 1907, another 239 lost their lives in a mine explosion in Jacobs Creek, Pennsylvania. National Miner’s Day occurs annually on December 6th, the anniversary of the Monongah disaster, as a remembrance of all lives lost in that fateful month.

Coal field fatality rates used to resemble the casualty lists from when America was at war. Thankfully, mining death rates have dropped significantly since Bloody December, due to new laws, safety inspections, and better safety equipment. Unfortunately, even with these safeguards in place, mining accidents still occur, as was a harsh reminder in 2006 when two separate West Virginia mine accidents killed 14 within a month. While National Miner’s Day honors our nation’s miners one day every year, these disasters serve as a daily reminder that no matter what we’re going through, it could be worse.
At HJ3 Composite Technologies, we work to make mines safer by structurally strengthening weakened components. We recognize the sacrifices that miners make every day, and in turn, try to provide a safer environment for them to earn a living. It’s just a small “thank you”. From all of us at HJ3, Happy National Miner’s Day!
Carbon fiber has been named the “building material of choice” by several industry experts, and is traditionally produced in large, continuous pieces, requiring big machines and facilities to support them. Smaller carbon fiber pieces have been created by 3D printing, but 3D printing, at this point, is highly impractical for large objects like bridges, rockets, and airplane wings. But what if it were possible to 3D print components of a large structure, and then combine them together to create a complete object? MIT’s Neil Gershenfeld and Kenneth Chueng asked this question, sparking the development of a new carbon fiber building system that could, quite possibly, revolutionize the way we build everything.
When combined together, carbon fiber “cubocts” can create infinite design possibilities. Photo credit: Extreme Tech
MIT’s revolutionary new design combines three fields of research: fiber composites, cellular materials (those made with porous cells), and additive manufacturing (such as 3D printing, in which objects are built by depositing, rather than removing, material). From the smallest objects to the largest structures, here on Earth and potentially in Space, MIT’s new carbon fiber “cubocts” can be combined to create airplanes, rocket fuselages, bridges, levees, and anything else you can think of. The interlocking carbon fiber blocks, reminiscent of the K’Nex or Legos of our childhood, are 10 times stiffer than comparable lightweight materials, creating very strong building materials with a very low density.
MIT’s “cubocts” are flat, X-shaped pieces of carbon fiber that can combine to build huge structures. Photo Credit: Phys.org
The bricks are constructed with carbon fiber that has been impregnated with epoxy resin and then formed into the shape of a flat “X”. Each “X” has a hole in the middle, which the leg of another “X” fits into, resulting in an extremely stiff structure of vertex-connected octahedrons, known by the researchers as “cubocts.” The cubocts can be added, removed, or re-oriented to build different structures with different strengths. For example, one structure could be built for resistance to twisting, while another could be geared more towards impact resistance. When tested for strength, the carbon fiber bricks were able to withstand an impressive 12.3 megapascals of pressure, with a very low density of only 7.2 milligrams per cubic centimeter. But the cubocts’ extreme strength isn’t even their greatest advantage.
The legs of each “X” are fitted into the centers of other X’s to create any desired shape. Photo Credit: Extreme Tech
Where MIT’s new technology really advances past other building materials is in the cubocts’ flexibility. While the individual X’s are very stiff and physically inflexible, they can be readily assembled, disassembled, re-oriented, and replaced if needed, resulting in a building application with limitless possibilities. Weaving different blocks together also allows for the creation of structures that are strong in multiple directions. Ideally, robots will mass-produce the carbon fiber blocks, and then combine them together to build any structure in mind. And eventually, the goal is to build carbon fiber materials that can reassemble themselves on the fly, depending on the given situation and which forces they need to endure.

While carbon fiber is considered to be a supreme building material, it can be expensive to manufacture and difficult to repair if damage occurs. MIT’s cubocts achieve the same lightweight strength that carbon fiber is famous for, without requiring the huge machines and facilities, likely reducing manufacturing costs significantly. And since individual components can be easily replaced if damaged, the cubocts provide even more cost savings and design flexibility. Pound for pound, the new technology requires much less material than traditional concrete and steel to carry a given load, reducing construction and assembly costs. Vehicles built with the new cuboct technology would have significantly reduced weight, resulting in lowered fuel use and operating costs.
The applications are infinite. The only question now is: will it work?
Since its introduction to the aerospace industry in the 1950’s, carbon fiber has become a “material of choice” across a wide variety of industries, including automotive, construction, sporting goods, and medical equipment, among many others. Its high versatility and incredible strength provides a solid value in many industrial applications.

A typical Earth Covered Magazine bunker. Photo Credit: US Army Corps of Engineers
Earth Covered Magazine (ECM) structures are built to safely store ammunition and explosives, and are frequently used by the Department of Defense and the US military. While they are not designed to resist the damaging effects from an accidental explosion, a structurally sound ECM can effectively limit these effects in an explosion caused by small amounts of ammunition and explosives. In this case, cracks initiated in the floor of an earth covered magazine bunker as a result of foundation movement and poor sub-grade conditions. Over time, the cracks spread to the bunker’s walls and ceiling, which led to leaks and concrete spalling. The bunker had lost its structural integrity, and considering the highly explosive contents within, required immediate strengthening.
The bunker’s extensive cracking threatened its structural integrity.
HJ3’s CarbonSeal™ carbon fiber was chosen as the strengthening system of choice for the magazine bunker repair. Prior to installing the carbon fiber, perpendicular saw cuts were made across all cracks in the floor and walls. HJ3’s patented carbon laminate strips were inserted into each saw cut, and the cracks were injected with epoxy to set the laminate in place. The rest of the bunker’s interior was cleaned with an abrasive blast to remove all delaminated concrete and dust. A cementitious grout helped to restore the bunker’s uniform surface, and finally, the CarbonSeal™ carbon fiber was saturated and installed along the cracked walls and ceiling.
The CarbonSeal carbon fiber is applied to the prepared walls.
The magazine bunker repair was successfully completed in just one day. By repairing the cracked bunker instead of replacing it and building a new one, the client saved a significant amount of money while simultaneously preventing the waste of several valuable resources by avoiding the manufacture of replacement concrete and steel. The repair prevented more than 4 tons of steel and concrete from potentially going to landfills, almost 250,000 gallons of water and 33,000 kWh of energy from being wasted, and more than 8 tons of carbon dioxide emissions from polluting the atmosphere.

Ceiling cracks aren’t uncommon, especially in older homes with plaster or concrete slab ceilings. Cracked ceilings can be a result of several different factors, including shifting with age, excess moisture from heavy storms, improper roof drainage, and too much weight from the floor above (see my previous blog, Ceiling Cracks: Causes and Remedies for more information). In many cases, cracked ceilings aren’t a reason to worry, but in other cases, they can be an indication of structural instability and will require repair as soon as possible to prevent further damage.
The cracked ceiling, prior to HJ3’s StrongHold installation.
The cracks in this ceiling required structural reinforcement, not just crack filler.
In this case, a home in the southwest US had developed a cracked ceiling as a result of too much weight from the floor above.
StrongHold’s carbon fiber is the strongest around, and perfect for confining ceiling cracks.
Like this one, many homes in the southwest United States are constructed with concrete slab or plaster ceilings, which are very heavy and susceptible to cracking and sagging over time. The concrete ceiling required crack confinement and structural strengthening to prevent any further problems. After researching her options, the homeowner decided to repair her ceiling with StrongHold™’s carbon fiber kits. StrongHold™’s experienced engineering team determined that applying the carbon fiber strips both laterally and longitudinally, in a checkerboard sort of pattern, would confine her cracks while simultaneously adding superior strength to the ceiling to prevent future cracking.
The paint and plaster are ground off prior to installing StrongHold’s carbon fiber.
Before the carbon fiber system could be installed, all paint and plaster was removed from the application areas with a mechanical grinder. A vacuum followed behind the grinder to rid the ceiling of any resulting dust and debris. After priming the ceiling, StrongHold™’s carbon fiber was thoroughly saturated on both sides and installed. Following a short (approximately 1 hour) cure time, the ceiling was ready to be painted to minimize the appearance of repair.
StrongHold’s carbon fiber straps are applied to the cracked ceiling.
A checkerboard pattern provides superior strength.
The homeowner’s cracked ceiling was thoroughly reinforced in just a few hours. By repairing her ceiling with StrongHold™ carbon fiber instead of a steel alternative, the homeowner saved a significant amount of money without adding any additional weight to the already-heavy ceiling. Since the carbon fiber straps are only 1/16th of an inch thick, the repair also didn’t reduce her room’s height, as a steel alternative would have. No excavating, drilling, or bolting was required whatsoever, and the homeowner has a stronger home than she ever did before!

You Love Your House.
It’s your biggest investment, your comfort zone, your shelter. You’ve decorated it how you want it to look, and you’ve probably shelled out a whole lot of money to make it yours. But now your basement, garage, and other concrete floors are cracked. Should you worry? What’s causing this blatant disrespect to your beloved home? And what can you do about it?
While concrete floors can be both functional and beautiful, they’re unfortunately prone to unsightly cracks and pitting. If not taken care of soon enough, some cracks can lead to severe structural problems, including total collapse. But not all cracks are created equally; some might be minor and pose no threat to your home or your safety. Before you crack open your ancient phone book to call your local foundation expert, it’s important to know what could be causing your cracked floor in the first place.
Why is Your Floor Cracking?
- Foundation shift. Your home will continue to settle on its foundation for years, or even decades, after it’s been built, and this is totally normal. But a foundation shift is different from home settlement, and is often caused by soil movement. The amount of soil movement beneath your home will determine the severity of your cracked floor.
- Soil movement. Many homes in the United States are built on clay or other expansive soils. In wet seasons, rainwater will saturate the soil beneath and around your home, causing it to expand and push against your foundation. In dry seasons, that soil now contracts away from your foundation. Your cracked floor is an end result of this expansion and contraction.
What’s causing your cracked floors? There could be a number of culprits.
Tree roots. Even if there aren’t any trees or bushes planted directly next to your home, their roots are often so strong and deep that they can push up against the underside of your foundation, causing your floors to crack.
- Soil saturation. As previously mentioned, soil movement can play a big role in causing your cracked floor. Soil saturation is the main reason for soil’s dynamic properties. Excess water from clogged gutters or plumbing leaks can saturate your soil, forcing it to move and crack your floors. Likewise, heavy rains and lawns that slope towards your home can overly saturate your soil, increasing your risk of a cracked floor.
- Substandard concrete mix or otherwise poor craftsmanship. When your concrete floor was first poured, it was a combination of cement and water. If the proper proportions of cement and water weren’t followed, you may have received a substandard concrete mix. According to the Concrete Network, water is added to cement to make it easier to install, but it also greatly reduces the concrete’s strength. As the water evaporates, the concrete itself actually shrinks. Wetter concrete mix will result in greater shrinkage, which creates forces within the concrete that literally pull the slab apart.
- Expansion and contraction. Concrete tends to expand on hot, humid days, and contract on colder days, which will often cause your floors to crack.
Whatever’s causing your cracked floor, the important thing to keep in mind is that floor cracks are often a symptom of a larger underlying problem. Simply put, cracks and pits in your concrete floor are also cracks and pits in your foundation.
What can you do about your cracked floor?
Repairing floor cracks can improve your home’s value, so even if they’re minor, it’s a good idea to repair them. But how do you know the difference between a minor crack and a structural one? Generally speaking, cracks that are wider than a credit card and running through the depth of your concrete are probably structural. They could be a sign of a much more serious problem, such as foundation failure. If you’re worried that your cracks are structural, I advise you to contact a structural engineer or foundation expert to diagnose your situation.
Structural crack repair is possible and easy, thanks to StrongHold’s carbon fiber systems!
But what do you do about hairline cracks that aren’t structural? Unfortunately, there’s no solid answer. But the Concrete Network provides some factors that you’ll want to look for in making your decision about how to repair your cracked floor, and how soon you need to do it:
- Is the crack static, or is it gradually growing? If the crack is widening, it may continue to do so if not repaired. While the crack might not be structural now, failure to repair it could cause it to become a structural crack.
- Does the crack present a tripping hazard?
- Is the crack wide enough to allow moisture seepage?
- Does the crack trap dirt, creating a maintenance or sanitation issue?
- Is the crack an eyesore, located in a high-visibility area?

Cracking at the joint of this parking garage required structural strengthening.
Parking garages are subjected to regular vibrations from vehicles and people passing through. Over time, these vibrations cause tiny cracks in the garage’s concrete supports. Freeze-thaw cycles, as well as moisture and oxygen penetrating the concrete, corrodes the structures and reinforcing steel within.
In this case, a parking garage at a federal building required crack confinement and structural strengthening at the beam-to-joint interface. Freeze-thaw cycles had caused the internal steel reinforcing bar of the supporting column to expand. As it did so, the tiny cracks caused by vibrations also expanded, allowing moisture and oxygen to further corrode the column’s concrete and inner rebar. Shear stress had caused the column to yield at the joint. Structural column restoration was required.
Prior to installing HJ3’s Civil™ carbon fiber system, all loose concrete was removed with chipping hammers. The surface was abraded and cleaned, then primed. Cracks and voids were filled with HJ3’s high modulus paste, and saturated carbon fiber was applied.
The column and joint have been fully strengthened with the HJ3 Civil system.
The HJ3 Civil™ structural strengthening system fully completed the column restoration in only 3 hours. The client saved 80% compared to alternative steel repair methods, and the flexible carbon fiber fabric made for easy application behind obstacles.

As a homeowner, you have a list 10 miles long of all the things that could potentially go wrong with your home. You probably also have a super long list of repair options for all of those potential problems. But, if you’re like me, your budget isn’t nearly as long as either of these lists, so you find yourself wondering how to pay for your repairs. You may have also realized that there are several Do-It-Yourself options that allow you to take matters into your own hands, allowing you to save money right off the top. But are all of those DIY options as reliable as hiring an expert? How do you know if your own DIY skills are adequate enough to perform the task at hand? What if you start a project, only to realize that you’re in over your head, forcing you to call a contractor anyway? Luckily, in the chaos of all of these scary questions, one solid answer emerges. And while it’s not applicable for every issue you’ll face with your home, DIY carbon fiber kits give you the power to structurally reinforce your own home in a matter of hours.
Unsure about your own abilities? You’re Stronger Than You Think! Installing StrongHold™’s carbon fiber systems is probably one of the easiest home improvement projects you can take on. As one StrongHold™ customer put it, “it’s easier than applying wallpaper.” People from all walks of Earth, with no experience in home remodeling or any other kind of repair project, have been structurally reinforcing their bowing and cracked walls and floors in less than one day. To date, StrongHold™ has been used in more than 10,000 homes without a single callback.
So what does it take to install a DIY carbon fiber kit? 7 Simple Steps:
1. Grind off all paint and delaminated concrete.
(You can rent a grinder from most hardware stores if you don’t have one)
2. Vacuum or brush away all dust.
3. Wipe the wall with acetone.
4. Prime the wall with StrongHold™ epoxy.
5. Saturate both sides of the carbon fiber fabric.
6. Press the carbon fiber fabric against the wall.
7. Apply another layer of epoxy.
That’s it! After installing your StrongHold™ kit, you can paint right over it to minimize the appearance of repair. If you decide to paint your wall, do so while the epoxy is still thumbprint tacky (about an hour after installation). If the system has already cured and you want to paint it, lightly sand the surface to abrade it before painting.

When a homeowner purchased this foreclosed property with a severely cracked wall, he knew he needed something stronger than mere crack filler or mortar to repair it. The ¼”-wide crack went all the way through the block wall, and was likely caused by soil displacement. The homeowner needed structural strengthening, and his research led him to StrongHold™. After reviewing the included installation video, he realized that the pre-measured and pre-cut carbon fiber kit would be very easy to install himself. Armed with confidence and The Strongest Name in Carbon Fiber™, this homeowner got to work.
Sunlight shines through the wall’s 1/4″-wide crack.
Before applying the StrongHold™ crack repair carbon fiber fabric, the drywall was removed from the problem area. The homeowner used a mechanical grinder to remove all paint and delaminated concrete, and he vacuumed the resulting dust away to provide a clean wall for the carbon fiber to bond to.
All drywall was removed prior to installing the carbon fiber.
After priming the wall, the homeowner applied StrongHold™’s carbon fiber fabric, which had been thoroughly saturated on both sides with the included StrongHold™ saturating resin. In this case, the crack occurred beneath a window, which had been previously removed; the homeowner wrapped both the interior and exterior of the wall. (Removing windows is not a required StrongHold™ installation step, nor is wrapping both sides of the wall. In most cases, applying carbon fiber to just the interior or exterior provides more than enough bond adhesion and strength to permanently confine your cracks.)
The homeowner wraps his wall with StrongHold’s carbon fiber fabric.
The repaired wall is ready to be re-finished.
While the StrongHold™ system was still somewhat tacky, the homeowner was able to drywall over it and paint the wall to create his desired look. By repairing his wall with StrongHold™, he saved $3,000 and a week of downtime as compared to a repair done with steel. In just a few hours, the carbon fiber repair provided him with a worry-free and maintenance-free strength that will last for decades! With StrongHold™’s carbon fiber, the homeowner gained the structural strengthening he needed, at a much better price. “I would definitely recommend HJ3’s StrongHold™ system,” he says. “It was a simple solution to kind of a tough problem.”
