HOW TO BREAK CONCRETE | 3 Different Ways to Demo Concrete 

I like this guy. Excellent video. I have an excellent swing with the sledge hammer but I am 63 now and can only take about 10 swings an hour. Using a wedge is also very handy. My latest project I used a BOSCH bulldog (an excellent light weight hammer drill with chisel tips) to create a slot then put the wedge into the slot for use with a sledge. The sledge would create cracks and after creating a crack the BULLDOG would easily take advantage of the weak spot.

Thanks for the info! Just what I needed for small footing removal

Excellent happy to have found your channel

Each gun is for a different type of job I’ve bin a mason my whole life ....for small jobs and brick the chipping gun is the best ....for slabs such as sidewalks , driveways , and aprons use the bigger jack hammer and the sledge hammer together Hope this helps anyone looking for advice other wise great video thumbs up ....ll

Thank you so much for an awesome experimental narrative and explaination.. P.S You've got some strong arms man !!!

Thank you.

Thanks that helped. Subscribed.

Anyone else find these sounds oddly relaxing

You Rock! Thanks for all the work you did for this video. It really helped me a lot. Great job!

Great video! You did a great job explaining for the beginners for sure! I’ll have to be back with an update lol

I came here exactly for this. I have a bucket of cement, only have a sledgehammer with me.

Very manly love it thank you ❤️

Thank you! All other youtubes were about cement slabs. I have 2 small concrete 'stumps' sticking out of my yard and need to remove. I tried manual and it didn't work for me. Was going to rent a jackhammer but it looks like the 20lb hammer will do the trick. Won't lie that I am a little creeped out about what I am uncovering. When I dig down around them it looks like a cement cap extended about 1-2' around about 6" down.

Think you should watch a video on how to swing a sledge, your gonna hurt your self. Your wrist are taking the weight when your pulling up you need to start further up the handle and let it slide thru your hands let the hammer do the work on the fall stroke.

It appears that the 20# hammer started at one minute not zero.

What about the heavy hammer with the pointy tip?

Two slabs of sidewalk that are buckled but not broken need to be replaced. I have a rotary hammer drill with the SAS bits, you think that'll do? Blunt force with a sledge?

In the Asia, you will see skinnier people hits harder. There's technique as the hammer falling, you slide your hand closer to end of the stick. This will give an effect of a whiplash where the hammer head is faster the further it is from the fulcrum. The benefits of this technique allows you to 1. Use speed to multiply the force 2. Experience less vibration 3. Less exhausting because you are letting the hammer do the job for you 4. Use energy only to lift the hammer

Reminded me of the the legendary Jack Henry vs the machine, but with a happier ending.

Man I was about to rent one of them big jack hammers or whatever. Nope! Went with the 20lbs and got the job done! Thanx bro!

Great video. But as everyone else, May I add my two cents. Please make sure you protect yourself from silica.

Nice work with that sledge hammer!!!

That was cool. Even though some old fashioned manual tools are just as fast i think one of the main differences is the amount of effort they take. Theres no way anybody could keep up a full speed effort like that with a sludge hammer all day. I could run 1/4 mile down the street faster than somebody could get in there car and drive it but they could drive 1/4 miles all day.

I saw David odells channel in the intro

Paul Bunyon beats the motorized devices ! Very Impressive .

My driveway connects my home to next door, they own 2’ in of it. Narrow & runs 2 slabs behind my home. Unused. Chain link set in towards small home. Watched your saw vid, thank you. This? Had me winded when done w sledge! Tough to gauge as I prefer precise, especially the closer to property line, where cut will be. 7’x12’ old slabs, telling me larger breaker. Maybe larger for majority of 2 ol pads & sledge along & in a ways from the cut line? Folks right there are far from kind & will be watching like a Hawk. Running privacy fence up to back line of the home, preserve some peace. Have chain link + gate I’ll pop out with a jack. 4x4 footings to anchor on top of concrete I own, left - on purpose. More protection & respect for the boundary line. Much rather sink 4x4s when concrete is removed. Mind lending your thoughts? Time is precious so, understood if no response. Thanks again for the videos, nicely done - each one.

great video; I like to rent a jack Hammer: Do they charge by an hour or by day ?, where can i get one ?

I'm a "desk lawyer" - retired - here in Ireland - swinging a sledge hammer to demolish part of the roof of a concrete shed - totally wrecked - I just don't have the muscles but I did get the job done - I didn't want to try out a Makita or whatever because I didn't wish to be standing on a structure, part of which I was simultaneously demolishing !! LESSON - unless you're as handy with the sledge as this guy is, try to use a power tool where possible !!!!

Ear protection?

I have two concrete base with a 6lbs sledgehammer that I believe will do the trick. Glad to hear you make mention of momentum because that was a part of my decision making between an 8lbs and 10lbs sledgehammer. With the 6 pounder, I should be more accurate and exert more energy....I hope.

Damn bro u bullied it with the hammer 😂 definitely have a new subscriber

Breaking up is hard to do!

Now wait a minute. To be a fair comparison, gotta compare times to the SAME DEGREE of demolition, that is, to the same size pieces. The manual method was not close to complete in that regard, and to get there, it prob. would have taken the longest time. I agree about the superiority of the pointy tip, but w/ method #2, two variables were changed---the tip and the size/power of the hammer. Not so instructive. I'm going with pointy tip and powered hammer.

Nah. I got have to get job where I can rest my game leg. All these kind of jobs are out. Maybe night watchman or something. Then again the night air might bother it.

Hi.i see, I feels that Makita tools on this videos, showing the badly, ways of slow ! Because, Makita , tools best on sawing wooden, metals , and ...... But, to molition 's rocks,sorry ....not good!

Machine will always beat man power.

A 20 pound sledge is best. Just don't plan on making as many swings and hits because it is heavy. Yep, you will swing slower. But, what happens is hammers bounce back when they hit something, maybe not much but they do. A 20 pound bounces back the least and so all of its' energy goes into the concrete. It hits harder and deeper. Always have the concrete unsupported or undermined to. have the least amount of work.

Good video, but bury those in the ground and see what happens......

if you put the concrete blocks on a hard surface, the sledge hammer probably could finish the job even faster.

Helpful! I need to break up a circular concrete basketball hoop support, so the 20# looks best which I would not have guessed.

Bad ass! Mad props to his man.. breaks rocks for fun! impressive.

Renos 4 pros & joes, Looks like I will be demo-ing a concrete patio, in the spring What do you think of the cross or curved ends on some of the newer sledge hammers designs, Like the Dewalt 12lb or the Roughneck Gorilla sledge hammer. Do you think it is worth getting ? I am also debating 10lb or 12lb ?

But your learning, the hard way where is your grandfather at hahah

Thank you for the insight Friend. 🧡💛😎

I think sledgehammer is fastest

Not correct technique in using sledge hammer.

John Henry, anyone read that story?

I would have offered you my 70 year old, 4 inch deep, slab to demonstrate the three choices. My loss. Very good video. facedanielsful's comment is the suggestion to handle the sledge hammer as you would a long-handled wood axe.

No grabber handle? Why didn't you have/use the grabber handle attachment with the 35 lb. Makita?

I got a huge chunk from an old fence post. Like a foot thick and three feet long. Its really old. Having trouble busting it up.

I have to cut up a 300 sq ft section of my driveway, which is asphalt. It's in bad shape, spotty pot holes and such. I'm guessing the small jack hammer might do me well enough to break it all up? The big hammer seems to be a put cumbersome.

Gotta learn how to swing that hammer bro, couldve been a lot easier, your working way to hard

Amazing 👍

Great job, you helped with my decision, thank you sir!

Good video, am doing this today. Four foot 12 inch deep slabs. Very slow going. Your concrete is fresh. Mine is twenty years old, much longer to chisel through it! Waiting on a chisel bit for the larger hammer to arrive, the little hammer takes a looong time.

Breaks easy when the concrete is a day old. 🤦‍♂️🤦‍♂️🤣😂

how do you break up concrete starting from the middle of the floor?

Can you add a description of each tool you used in the information of the video.

🤣 oh boy! smh.

Buen video 👍

I need a nap watching this. I'm going the same thing in the basement.

Beautiful job !

It's a shame there's no way to reuse those buckets... :(

My dad and I really enjoyed this video! Thank you. We are removing old fence posts and have to bust up some concrete.

Thanks, subscribed, off to my cemented fence post again😩👌

Not handy with that sledge hammer...

Love your video. I will subscribe

An excellent video 😂

😂😂😂😂😂😂

This guy is a beast, congrats!

ء😈😬😈😈😈☺

Thank you! Great video

awesome vid

Hell of a workout

Thank you man!!!

brilliant video!! cheers!

Nice job!

Great video

Surprising!

Thanks for the video. Helped a lot. Have to demolish two concrete post bases. Subscribed and liked 👍

Nice video! Thank you!

Great video. But it was also very entertaining to watch you struggle with the hammers, pretty good! :-). How about cutting cement in a rectangle 6 inches deep. Which toolset do you recommend? Thanks

Totally unfair comparison, not to mention that you're using the sledgehammer wrong. This is on just a small bucket of concrete. Now let's see you do a 4 foot x 4 foot slab of concrete or some other "real life" situation. You can't do it. You got worn out busting just a small bucket of concrete.

I do not like the video

I have to break a 9 inch width 3ft tall and about 3 feet long. It has rebar in it. Mix was quikrete 5000. What type of jack hammer will I need? 2200 watt or 3500 watt?

jak si mtjb ko bik, al ne znaš sa mašinama

This was beyond pitiful.
