if you have Microsoft Excel, you can make your own.

1 ton of concrete sand will cover 200 SF at 1-inch depth.

For aggregate, lets say 5" depth - I use this:


So if you have a 20x20 patio with a 5" base it'll look like this:

20x20x5 = 2000 divided by 12 (converts the inches) divided by 27 (converts to cu yds) = 6.17 x 1.2 (converts to tons) x 1.5 (to factor for compaction) = 11.11 tons

A formula my estimating system uses. been doin it this way from day one. works for us

"It's You vs. You"

"People Throw Rocks At Things That Shine"

My Equipment Brag List:

-1 CAT hat
-16 pairs of Hanes socks (the Heavy Duty model), many with holes.
-12 pairs of underwear, ranging from Joe Boxers to Jockey, many are in need of replacement. (no more photo requests please)
-hundreds of t-shirts. Some w/ grease stains, some torn & tattered.
-7 pairs of jeans, ranging from Levis to Polo to GAP. 1/2 of them have holes in 'em.
-1 belt
-1 pair of old worn out Nike shoes.

Construction Master calculators are pretty helpful as well.

they can convert feet to inches and yards, square and cubic. areas of circles etc etc. all the math functions built in. as well as the Pythagorean theorem for squaring up.

check home depot or amazon.

this is my formula it has always worked almost perfect for me.

Length x width x inches of base / 240 if you want tons multiplied by 1.5 this accounts for compaction

the 1.5 for compaction was the issue. Thanks.
