How To: DIY Concrete Weight Plates That Don't Break

Today, we build DIY Concrete Olympic Weight Plates so you no longer have to refresh your browser until your fingers fall off.
We've made a lot different DIY gym equipment projects over the years, but this one turned out as good or better than just about any other we've done. If you need plates for your home gym and either don't want to spend the money or can't find them, these are a good option.
I plan to use mine for pavers in my backyard. Ahem.

The secret is to over pour the concrete then take a concrete grinding blade and grind it down to exactly 45lbs, it will also make the backside smooth then spray it with truck bed liner

you don't need to add a lot of something to appreciatively change its microstructure. While I am not very knowledgeable on concrete, steels will only contain around .5% of carbon by mass and they are very different in terms of strength than iron.

[@davidmoore1880]

@@thomas7365 microstucture, yes. But notice, the fiberglass he is adding is only the version rated to help with initial cracking during drying. To help with cracking during usage, more, longer strand, is needed.

[@rezanadaf1213]

@@thomas7365 What you are talking about is called an interstitial alloy (this rearrangement happens at a molecular level). This is done by smelting, therefore the carbon atoms (much smaller in diameter) are able to fit between the much larger metal atoms. Because the molecular weight of metal atoms (could be any but likely Fe: iron) is much higher than that of carbon per mol, the percentage by mass will be greatly skewed towards the metal, however in terms of the number atoms, this ratio would be much less skewed towards the metal because of the difference in molecular weight, which is measured per mole (as it compares to Avogadros Number when counting atoms individually). Therefore though the mass percentage of the alloy will be skewed towards the metal, the atoms making up the molecule will be a much more neutral ratio, though still skewed towards the metal. This process works differently (adding fiberglass to cement) no LARGE molecular changes are happening here because this is simply a mixture as opposed to a solution (wherein chemical composition tends to change). Think of a rock in water (a mixture) as opposed to salt dissolved in water (a solution).

[@thomas7365]

@@rezanadaf1213 Thank you for the clarification on interstitial compounds. I agree that a change in crystalline structure will likely have much greater change on strength and crack propagation resistance of material, but microstructure of material is also very important, and from what I've researched fiberglass can appreciably change this (not so much of the concrete itself but the underlying fiberglass matrix seems to form a microfiber heterostructure within the concrete).

[@jasonpeng5798]

@@nathannewman6555 a deadlift is a compound exercise working both your legs and your lats. A heavy deadlift is just an overloaded version of that. You can overload your lats by doing front lever holds, and your legs by doing pistol box jumps. It will provide the same gains as doing deadlifts and by the time you're back in the gym your deadlift will have increased

[@nathannewman6555]

@@jasonpeng5798 Fair enough. I'd still argue its not efficient. You are doing 2, practically 3 exercises to replace one. I say three, because with a pistol squat being one legged, you'll have to do both sides. They are also still a bit different based on progression. To progress on a deadlift, you simply have to add weight. In Calisthenics, you have to add reps and at some point, change to an entirely different exercise. Weight training doesn't limit you from changing exercises or reps, that's just another option.

[@haltorne6647]

Additional tips: •water weight in the concrete evaporates out •overcast and use angle grinder to grind down to weight/smoother finish (read last tip for what overcasting would be) •if you get a super rough finish, use some concrete repair mix to smoothen it out •if you're gonna spend money on fiberglass reinforcements, use more than that tiny amount •use sch 40 PVC and coat the outside in rubber (either spray on or tape or a rubber sleeve) •spray on truck bed liner to coat the entire plate. The large plates come with a 17.5" diameter which puts the surface area of the plate right around 8sqft. Truck bed liner is supposed to be 0.7lb/sqft at 1/8" thickness. This extra thickness also bumps that 17.5" diameter closer to true size of an oly plage diameter. This means you're getting about 6lbs of spray on rubber into the plate so only pour about 40-42lbs > grind off about a pound or two > lose some water weight from evaporation > spray truck bed liner evenly until 45lbs

[@Dsquaredforever]

Concrete doesn't lose much weight when drying. The amount in these plates would be negligible anyway. The water molecules react with the mix, hydrating it and losing energy to heat, not evaporation. The oxygen and hydrogen ions don't leave the mix, so the weight of the water stays.

Just LOVED that video. !!!! Got a suggestion I think you and your viewers making these might like I recently bought 2 concrete blocks to do squats with a dip belt and a pair of dumbells while standing on. I didn’t want the blocks to crumble and make a mess in the garage so I went to Home Depot and bought a can of Flexseal - that rubberized stuff in a spray can you see on TV all the time to seal concrete etc to stop leaks. Sprayed both blocks in white to prevent black smudge makers and the stuff worked PERFECTLY!!!!!! Sealed the concrete - no dust or crumbles and if put on in a 2d or 3rd coat would probably be great protect for your concrete weight plates. I got my first weight setback in 1967. 110 lbs of interlocking plastic weights - advertised as not to damage floors. What they really were plastic molds which had a pour hole for concrete which were than sealed Finally got rid of them in 2012 so I definitely got my money’s worth out of them.

When using concrete plates, you're already adapting to a new way of doing things... so it's probably best to adapt the workout with them as well. My point; if you're a bar-dropper... maybe start adding an eccentric movement to the end as opposed to the drop - which will trash them over time, especially with no rebar.

I just finished my first 45. I measured the dry concrete before mixing so I'll see how accurate that made the weight. I used the hot glue seal instead of silicone though and the hole came a bit loose and is just off center as a result. Will try more glue next time. I also bought the refill kit from Caveman as they are significantly cheaper, but not metal so I'll compare how they hold up in comparison after I have at least a set of each.

Why not put the molds on the scale, zero the scale and then pour to the right or closest weight to be more accurate?

[@aboutthearthur]

You also have to consider the water weight that evaporates/bakes away. I think alternately, the best strategy is to pour too much by a couple pounds intentionally, then sand down that rough backside of the final dried plate to get to exactly whatever your target weight is.

[@donay3773]

49lb in wet concert is the sweet spot then after drying it would be 45lb 46lb

[@danielrumbo343]

@Eric Gatlin nice send the video sanding concrete. Lol. The balance on the weight is also a factor I think

[@KenJones1961]

Tare out your 5-gallon bucket, add your metal pipe and concrete to 45lbs. Put your pipe in the mold, mix your concrete, and pour. It should dry out darn to close to 45lbs. Tare, for those who don't know, is zero to empty weight in simple terms. Place your bucket on the scales and hit zero. Then whatever weight you put in, the math is done for you.

[@perspectiveflip]

This would also ensure that the plates are the same weight afterwards

[@kiwislice6935]

Biggest problem I've had with caveman molds is popping out the plate (even when lubicant is applied). This seems to solve that problem! Just flip it upside down and let gravity do the work. Its more expensive but a huge time saver! Great video!

[@bradskarin2117]

As others have mentioned you should tare the scale first. Also, I made some concrete plates a few months ago and made sure to make them slightly heavier than what I wanted. Then once it is cured, go back with an angle grinder with a concrete disk on it and you can shave weight until to get it exactly what you want. Obviously there will be slight weight variations as you use them, but this gets you really close to exact desired weight.

[@josephmoore7403]

Did this 3 years ago to great result. Couple tips: 1) use a layer of rebar in the middle of the plate. 2) don't buy a kit, buy a pair of cooler tubs and 2" pvc for centers. 3) after weight set up, pond cure them for a few days. 4) buy a mixing drill bit, cheap and worth it

I used rebar instead of the concrete fiber to hold it all together. I have yet to have them break over a month of heavy lifting with them.

[@ultimaetsolder]

How did you cut the rebar?

[@mattkaplan1316]

ultimaetsolder use a angle grinder if you can if not a hacksaw are very cheap and work well

[@PangitBear]

ultimaetsolder I didn’t cut anything, I used a 3/8x12 rebar that sat around the PVC to hold it in place

[@Mark-sn6kh]

Or chicken wire, hog wire, or just concrete reinforcement wire/mesh.

[@kingturtle1000]

Don't forget to seal the concrete. Also some rebar or just something in addition to the fiber glass may help in longevity.

[@JamesPhillipsOfficial]

Steel mesh works well, i saw on buffdude dads channel, he made the barbell as well with 2 inch collar

[@DorkyThorpy]

I was thinking steel mesh. Or fencing mesh, or chicken wire,

[@stevecozart183]

Been training with concrete since June... Solid training alternative if you dont have access to plates (at least for now).

[@TECHNICIANIAM]

Yo hell yeah. Thats sick man. Definitely saving the vid to make my own

[@ConnorNolanTech]

I've seen people selling concrete plates on craigslist made with these molds.

[@ohms2754]

How much were they?

[@PangitBear]

Omar Alcantara crazy expensive for what you could make yourself

[@ConnorNolanTech]

@@ohms2754 yeah, they were being sold for like $1.80 per pound, which is crazy when you know that concrete is under $5 per 80 pound bag.

[@stixandstone]

Connor Nolan I cant do anything about gougers and resellers. I have called a few out that I have seen in my area.

[@ConnorNolanTech]

@@stixandstone I definitely don't hold other people's actions against y'all guys. Craigslist is always just going to be full of people trying to squeeze every dollar possible out of people.

[@PeteQuad]

i need some junky plates for sled pulling, this might work well.

[@stixandstone]

A lot of strongmen competitors have done this for sleds, yokes, frames, or anything that needs to stay outside or stay heavy.

[@corpo33]

Just got a set of these moulds today for my birthday cool video bro.

[@lianaburless1835]

I would never be able to do it right. Mine would be lopsided lol. Your right it is hard to find weights. I jist keep checking to see what I can find one day to the next and get lucky sometimes

[@ahoff64]

Texan: *sees State of Texas on product, immediately clicks thumbnail, regardless of content* Everybody else: "Oh hey cool another useful DIY video."

[@stixandstone]

Neither person is wrong 😂

[@markharlow]

Great video. Save people some money!

[@therussianbikeman4716]

Have you seen how expensive the moulds are ....

[@amfitness5598]

You are not saving that much. The main thing you gain is the ability to make as many as you want. You also have to factor in the cost of materials etc besides the kit.

[@threatassessment216]

Your moustache is fantastic you’re a wonderful man thank you !

[@ejsgarage]

Good job! Thanks for the tutorial 👍😀

[@dpa552__]

Maybe put the mold on the scale, tare it and then add the cement.

[@slimmark5526]

Some of the weight is water that evaporates out

[@williambilinski]

Inexpensive, temporary alternative 👍

[@doloman77]

I would make a few for maxing out on a leg press machine in my garage gym , don't need to keep buying just so I could max out a leg press , great content bro .

[@j-fluencer]

That was awesome!

[@eduardoferdinandi3931]

Tip: pour extra and shave the back to exactly 45

[@stixandstone]

Concrete calibrated plates!

[@Rich_Lahman]

Do another review. Drop them till they crack. How many times does it take to crack the plates from shoulder height?

[@vance9090]

Richard Lahman would you drop iron plates from shoulder height?

[@Rich_Lahman]

Vance Young sure! For science, maybe we should see how they would perform. Does a cast steel plates do better than a machines plate. I don’t think I’ve seen a video that have done it. Common sense would say no, I wouldn’t drop steel plates, but let’s see the video for science. Drop them on rubber pads would be fine to observe.

[@JosiasBernal]

Your work is amazing bro ❤️

[@brandonvanmeter]

That's a money saving idea in the long run

[@SkullCrushersClub]

Coat them in Line-X to make them invincible

[@kbi4givin]

1/2 the size of me... that dude has to be HUGE!!!

[@javiersanchez349]

That look's great! I just didn´t understand what was the determining factor that prevented the concrete from breaking. Can someone explain me pls?

[@erikborg5497]

Thanks for sharing, plate shortage has been awful!

[@PracticalBibleStudies]

I did this when I was a teenager. Instead of lbs I just put "a lot."

[@JoshuaWilliamsMA83]

Made my own using a 16" Sonotube and 2" PVC pipe. 2.5" thick comes out to 40 lbs exactly.

[@vipnetworker]

That’s a great idea. How are they working out?

[@JoshuaWilliamsMA83]

@@vipnetworker they're working great! I need to make a few more so I have enough weight for squats and deads. I only made 4 plates initially.

[@JoshuaWilliamsMA83]

@@vipnetworker they actually sell bags of fiber reinforced concrete at my local hardware store. I also used chicken fence wire for reinforcement.

[@sarahconner9433]

16 sonotube is way expensive though...I like your ideally

[@JoshuaWilliamsMA83]

Really? Where I'm at, a 16" cardboard sonotube is less than $8 and bags of fiber reinforced concrete are less than $6.

[@kwwillson]

This is pretty cool man. Thanks for posting it.

I just learnt something from my dad (Coop). Thanks dad!

[@krishnai2640]

Strength of concrete decreases as you increase water content

[@ltlwatcher]

Someone should start a business making concrete plates

[@polynesianmovtgp7439]

Soon we will see a company start doing it guarantee

[@johnniebattle6656]

This guy is freaking hilarious!! Two thumbs up!

[@Corlentor]

Awesome result. I bet if you spray them with an underseal rubber coating after they've set it would increase the longevity and drop resistance. Could be worth a try.

[@anderson2989]

Nice advice

[@MajesticSkywhale]

This guy needs to make a dumbbell mold!

[@_Car_Ideas]

You can just buy Olympic dumbbell handles, they’re usually around $100 for a pair (make sure you buy a different set of clamps though, because they all usually come with cheap clamps), and then make your weights.

[@MajesticSkywhale]

@@_Car_Ideas i have an adjustable dumbbell set. I want to build a set of regular dumbbells, with flat bottoms so i can rest them on my knees instead of getting jabbed in the quad by a metal pole

[@amfitness5598]

You Have to Live It you need to invest in IronMaster quick-lock adjustable dumbbells. Problem is they are not available right now but if you find a pair on the secondary market for around the same cost as new I’d buy it. Worth every dollar. I’ve had mine for 2 years they get used a lot. The square look was weird at first but they feel more like traditional dumbbells at a commercial gym than any garage dumbbells I’ve ever used including power blocks . Plus they come in several expansion sets.

[@JamesPhillipsOfficial]

@@MajesticSkywhale you have to realize there are no good diy adjustable designs excepts the long pole version or the Ironmasters which cost £1200 for the 75kg per hand or £350 for 36kg per hand. If you cannot buy, Once you get actually strong then that space on the pole would be filled anyway and you can rest them on the floor. You could have a circus dumbell that is "fillable" but they are quite big. You can use lead-rolls as well for dumbell

[@MajesticSkywhale]

@@JamesPhillipsOfficial I do realize that lmao, that's why I want to make concrete ones. I have a circus dumbbell too.

[@ChristhianGT]

We need a week update on those.

[@stixandstone]

Well, I’m five months into working with my first set of concrete plates using these very molds and they are still going strong. Only a bit of chipping on my small 10lbs because I wasn’t paying attention and it smacked my jammer arm post.

[@ChristhianGT]

Stix And Stone awesome

[@djaric]

ive been using concrete tube forms and pvc pipe to make weights. The tube also protects the concrete somewhat.

[@Vladimir9857]

Great video bro, thanks.
