@@samadheidari8880 the amount of waste is determined by how well you think you got your measurements. You always want to have enough, you don't want to be a little short.
How what a complicated way to figure that. Just do L x W = sq ft. Divide that by 81 to get 4 inches. Then just double it for 8 inches, triple for 12 inches, etc, etc.
I have never seen this method but it does work. But If using a calculator I don't see how it is any easier. Thanks for the info, I can teach it as a second method, this method may be easier to understand for some students.
I do understand the way you explained. I’m into it.
How do you determine the width x depth of a footing for a slab? Trying to figure my project and cannot find that info
It depends on the type of soil and the weight of the building. Ask a local contractor, they should know.
Is 10% waste concrete normal for small or big concrete pouring?

where does the 27 come from?
There are 27 cubic ft in a cubic yd
Works for block walls as well right? Footing L x W x H ÷27 ?
Yes, you can put a block wall on the footing using that equation for the concrete
am I missing something ? I added everything and did not come up with 190
If you add all the numbers for the perimeter 50+30+15+15+20+15+15+30 they equal 190 linear ft
Sorry, I’m so confused. Isn’t length supposed to be the longest side of an object? Wouldn’t 190’ be the perimeter?
@@circlehomeservices8917 the footing goes all the way around perimeter, so length of footing = perimeter.
@@timpalmer-logstolumber1999 ohhhh, that makes sense. I thought these were isolated footings, so I was confused
@@circlehomeservices8917 if you have any other questions I will be happy to answer them.
Thank you for your knowledge. Saving me from flopping on an estimate
Wat abt rebar
@@Salimabdul-n4u the amount of rebar will vary from place to place and building to building.
This man seems a little shy but double sharp. He instills an odd confidence. Reminds me of a Skyrim Greybeard.
Thank you!

@@timpalmer-logstolumber1999 maybe it just seems easier to me because that how I learned it when I was a kid. I don’t math too good😂
Thank you sir
So in my class I learned that the length is calculated by center line
There is usually more than one way of doing things. The main thing is that you have enough concrete and not a little short.
thanks bro, much appreciated, very berry much
So basically we waisted 6 minutes to learn something that can be done in 30 seconds or less by an online concrete calculator. Good stuff.
