    Hi, I am installing a 15 x 20 foot patio behind my house. I was told by a local supplier that I would need 4 tons of 2a limestone. my question is: How think of a base would that give me?
    I am not sure how to do the calculation.
    thanks in advance:rolleyes:

    Your supplier is just a little off. For a 6" base you'll need more like 8 to 8 1/2 tons. 4 tons would give you less than 4" after compaction.

    You should have a base 4"-6" with 1" of screed sand when you lay your pavers(unless your doing concrete, then 6" base with 4" of crete).

    The calculation is: L x W x D / 27 = Yards/Tons

    20'L x 15'W x .5 (6") D / 27 = 5.5555
    20'L x 15'W x .333 (4") D / 27 = 3.70 yards

    So you're either buying 6 yards or 4 yards mathmatically. Of course you'll want a foot or so on each side that is exposed for support. So your 20x15 turns into 22x17 for your base, depth (D) stays the same.

    22'L x 17'W x .5(6")D / 27 = 6.92
    22'L x 17'W x .333(4") / 27 = 4.61

    Have fun. Make sure you get 2A or 2B modified

    Don't forget... One cubic yard of granular usually weighs more than one ton. I usually multiply by 1.4 to achieve proper weight of material to be delivered.
