concrete
 

I tried the formula for measuring concrete and came out with a different number 3 different times. I need enough to pour a 15 x 30 slab. Any framin' carpenters here?

How thick you goin?

My wife just informed me it's 14 x 42. I'm not puttin' walls on it....it's just to park on. 4" thick, I guess.

roughly 5 1/2 yards for 4 inches thick and 8 1/3 for 6" thick

if its going to have any kind of structure on it you will need footers

Salty it comes out to 7.2 yards. Who ever you buy from, let them figure it, just in case they screw up it's on them.

7.25

order 8

Good idea.

Thanks fellows.

7.26,if you round up.lol

If I wanted to resurface my driveway while doing this.....would the existing concrete have to be busted up and removed?

It is definitely the thing to do, it gives you a chance to use sand to level and have a solid base to pour on.

I know people who tried to pour over existing concrete to save a $, but you end up with the same result sooner or later, busted driveway.

To try and even do it right is very labor intensive, drilling through existing concrete and and driving rebar for extra support, not worth it.

If you do your driveway, and demo the existing concrete, don't let whoever you get to do it fool you. Don't let them try to charge you extra for the "disposal" of the concrete, either they grind it up and reuse it themselves or they sell it to someone who does it. People are buying this crushed reclaimed concrete instead of limestone, it is cheaper and packs better than limestone.

Even if you resurface with asphalt, demo the existing concrete.

Good Luck, hope this helps!

If you go this route, you can rent Bobcat with jackhammer attachment and bucket , and rolloff box and save yourself a lot of money. I don't know about that area, but around here they charge an arm AND a leg to do demo/removal....It's also handy to have a burning rig to cut wire or rebar in existing slab.

:eek:

HOLY CRAP!!!!!!!!!!!!!!!!!!!!!

That existing driveway is starting to look real good just like it is huh??:work:

man i don't know who ya'll been using in your areas but if they charge for all that your insane for using them. my dad is a general contractor his company's name is concrete concepts inc. give him a call. 225-751-9713.been in business for 25 plus years. mainly does commercial but let me know before you call and he can make a exception.

I rent construction equipment. Could get you a Bobcat and breaker for nothing. I will even operate the skisteer. All you have to do is let me take a picture of you covered in LSU gear. We are out of NO. You just have to pay for the deisel.

:*****:

Thanks for the offer but I'll pass.

you ever looked into the miracle crete my helper on his time off helps his fiances family do it, comes out really nice.

A dood is coming tomorrow to give a quote on the entire job.

LxWxD / 27 gives cu yds...right?
 

sorry i'm late with this...but

length x width x depth / 27 should be the cubic yards...

just remember to convert depth to a decimal...

so 14x42x.33 = 194/27 = 7.18...

round that up to 8...

$6700 labor. $5100 of it is to bust and remove the existing slab. :eek:

Why Would you spend all that money on concrete? I'm sure your about to kick the bucket...should be saving That money for a tombstone!

My wife's got plenty of it. Besides, I figured my pals in the Sports Bar would pay for my tombstone.

ill definitely chip in!

If we pay can we put on it here lies the biggest LSU fan ever.*****

Sure....I won't know anything about it.

what is your wife's cell # please? :grinpimp:

"Here Lies Salty...Biggest OU Homer ever"

OK....we're ready. 1850 sq. feet. I got a price of $3.00 psf to bust, remove, form and re-pour the driveway, and, where there is no slab...$1.50 psf to form and pour. This is labor only. I will have to buy the wire, visqueen, concrete and any dirt needed. The dood comes highly recommended and I have seen his work. How much for the concrete? My wife is buggin' me for at least a ballpark figger.

100/ yd

thats a good price, you don't need no stinking wire if you use fiberglass concrete. And if the slab is out in the open you don't need no stinking vizqueen either

i remember we talked on the phone about slab thickness due to the fact you were gonna have semi trucks on this slab . what thickness did you decide to go with?

No semis due to insurance purposes. Plus, I'd have to bury some cables 'cause they can't get under. The dude said 3 1/2" would be cool but with 4000# mix. My boat slab was poured with 3000# mix and hasn't cracked yet.

What's this 100 yard crap?

It means bust out some mooolaaa.....:p

[quote=Bluechip;184649]:shaking: He must mean $100 a yard. Ain't no way it takes 100 yards.

That is the cost of concrete.....$ 100 per cu. yard. So if you need ~ 8 yards it will cost you ~ $ 800.

In Lake Charles it think it is a little cheeper....maybe ~ $ 90 per yard.

If you are digging up the driveway out to the street.....make sure ALL the driveway is dug out to 3.5". I have seen many driveways "skimp" on the thickness next to the road and where a drainage pipe crosses under the driveway.

IMO.....the driveway should be "flaired" where it connects to the road. This makes it easier when turning into the driveway.

[quote=Salty;184651]Yea....that's what I think also..

So, how much concrete to lay 1800 sq. yards 3.5 " thick? What mix...3000, 3500 or 4000#?

make sure you tell them you want fiber mesh in the concrete. if you tell them fiberglass they will know you don't know what you are talking about, then they will send the trucks to you light. meaning if you order 5 yards they will only send you 4 or 4.5 cause they will not think you know what you are talking about. when you call for that extra yard you will find out that there is a 3 yard minimum. thats how they get ya. so don't let them know that you don't know nothing about it.

1800 sq ft x 3.5"/12 = 525 cu ft.

525 cu ft / 27 cu ft per yd = 19.44 yards of concrete.

Ordering 20 yards of concrete and you could end up just a little short.....depending on your measurements.

What mix.....I would go with at least 3500#. But ask them what is the price difference, 4000# may only cost a little more. I would only use 3000# concrete where it will have very light load. Such as a patio or slab to put a small storage building on.

I was at work when my drive was poured and I ended up having 2 spots where after a rain, there is little [1' x 2'] water ~ 1/8" deep. It is not much, but it does create a slick spot. IMO....it would be much better to have a crown in the center or sloping to one side on the concrete to be sure it drains well.

Concrete takes a long time before it is "strong". The concrete, under ideal conditions, should "cure" slowly. Most of the curing [or drying] process takes place in the first few days and has about 70 % (if I remember correctly) of it's strength after ~7 days. After about a month, it has ~ 90 % of it's strength. 20 years later it is still getting stronger. These number could be off some.....can anyone correct me?

To slowly cure.....espically when it is 95 deg outside and the sun shinning on the concrete....it would be good to keep the concete surface wet for the first 24 to 48 hours. This is not required...just good to do and may help delay any cracking in the driveway. I said....Delay....because some cacking is inevitable. I have seen driveways covered with visqueen (sp?) to hole in the moisture to slow down the curing process.

Salty, I've got to ask. How did you go from a 14' X 42' = 588 sq ft drive way project to 1800 sq ft project? Your wife must be like my wife (except for the money part). Are you going to concrete your front lawn so you don't have to mow? I put a block on the home improvement channel yesterday. She will freak when she finds out. I'll put it back.

...plus tax plus deliverey............ the only way you are gettin it cheaper is if you got a finisher that pours industrial or other huge jobs where he gets better deals because of the volume he does , then still he probally wont pass the savings on to you that goes in his pocket!

Well, she thought that the 18-wheeler would be able to back right up to the fence and we could just dolly the stuff into the storage.....10' away. Coke came and looked and said that there's no way they can back a truck from the street...too tight quarters. I suggested just a walkway to the storage but I lost the arguement. :eek: We're pouring the driveway 8' wider + busting up and re-pouring the original driveway.

What does an 18 wheeler loaded down with coke weigh???????? An 18 wheeler that hauls freight can weigh up to 80,000 lbs. If you figure how much weight per tire.....the 18 wheeler has ~ 4 times the weight per tire of a car. Each tire in the 18 wheeler is much larger [surface area] so that does spread out the weight some. But the truck is still very heavy.

Just wondering.......whey can't the driver put the cokes on a dolly and bring them to the storage building on a sidwalk. They do that all the time when they deliver to stores.

You may have to rethink pouring the driveway with something more that 3.5" thick concrete. Just guessing [this is out of my experience] maybe 6" thick.

I would not allow that 18 wheeler to get on the "new" concrete for at least a month after it is poured.

After making my post late last night......I got to thinking the same thing. The size of the job got 3 times larger.

Those are going to be some expensive cokes.

There isn't enough room for the 18-wheeler to make the turn onto my driveway. It will cost my wife almost $7000 per year for liability for the Coke guys to enter our property. They will just block the street and unload the Cokes onto a dolly or cart. Guess who will be wheelin' the Cokes? :smokin:

Your WIFE ????????

Does this mean the project has been scaled down to unloading on the street?

Have you considered just renting a storage building somewhere in town????

I am guessing these cokes are not just to drink at your house. The cokes are part of the candy and frozen stuff you have in the air conditioned storage room.

Yes, there are no climate-controlled storage facilities close by. I already sold my boat and turned a large portion of my boat storage into climate-controlled storage. $3000 later....I ain't fixin' to go somewhere else. I just have to decide the best route to get the products from the street to inside my back yard....and the easiest.

Maybe your lawn mower or 4 wheeler and a small trailer.

If it is a straight shot from the road to where you store the cokes......maybe mount an electric wench to pull a small trailer?

How is your back for unloading the cokes? You got any neighbor boys that could help stack the cokes?

It is a straight shot up the driveway (65'), but, when you hit the grass is the problem. That's why I thought of off-setting the driveway when it reached the carpor(ch) and extending it all the way to the double gates on my privacy fence. The storage is in the back of, what once was, my boat shed. Once I reach it...it's a piece of cake. This fancy dolly/cart my wife bought does not roll well in gravel or grass but you can roll it with two fingers on a concrete surface. My back is willing and able right now but I'm considering surgery(don't know yet) and I'll be out of commission for 6 months as far as doing this kinda stuff. It's not only Cokes. There's ice cream, chips, candy...the whole 9 yards.

BTW...1 case of Coke (20 oz. bottles) weighs 36 lbs. The cart will hold about 16 of 'em.
