How much gravel would I need to backfill a cavity 25' long, 3' deep, 2' wide?
tp,
Are you a product of Illinois Public Education?
LOL!
I'm figuring 5.56 cu yds,
converted to 7.5 tons of gravel... now that is assuming 100 pounds per sq ft of gravel.
Who you burying?
Just ask the engineer, good stuff Judge :00hourA cubic foot of dry, loose gravel with 1/4" to 2" stones weighs approximately 105 pounds per cubic foot. So, a cubic yard is that times 27, or 2835 lbs. (There are 27 cubic feet in a cubic yard). The measurements you provided for the cavity that you want to fill calculate to 5.56 cubic yards as Ripken pointed out so you would need approximately 7.89 tons of gravel. The national average price for fill gravel is around $6.75 per ton.
Vinnie, always trying to one up someone on gravel questions! :mj07:5.94 you forgot to add 7% for settling :SIB
