View Full Version : Drive Way
Tearing out a 1,211 sq ft concrete drive way, making the drive larger and installing 1,463 sq ft of 21AA Limestone. If I want to put down 5-6 inches of limestone, how do I figure out how much to order?
I failed High school math.
Is the equation the same for 21 AA Crushed concrete, and gravel?
One more thing, the home owner got a price for concrete, just install concrete, not removal of existing drive way, and the contractor gave him a price of 9.50 per sq ft. Does that seem a little high or low to you guys.
I gave him a paver price of $10 per sq ft for his drive. I thought concrete was much cheaper then pavers, or am i wrong?

basically what i do is take your sq footage multiply by how many inches and then divide by 324......you'll get how many yards of whatever it is your using.
so 1,443 ft sq i round up to make sure i have enough....
1500x5inches= 7500 then divide by 324 = 23 yards
crush run is about 1.5 ton per yard it will vary depending on rain
also we charge $17 a sqft pavers are better than concrete you have to make sure your customer knows this. check out http://www.icpi.org/ for help with that!

never charge pavers by the sq foot!

your absolutely right! but thats what i average. def depends on conditions
Thanks for all the help
Its not that I gave him a flat sq ft rate, thats what it came out to abouts when I divided my price by the sq ft.
how many yards would you add for compaction?

Here, I cheat and use this local concrete company's website all the time when figuring cubic yards: http://handymanconcrete.com/html/cont_calculator.html
I can do the math but most times just choose not to.
