Sand & Gravel
The color is a mixed white and gray with a few tans.
Available sizes are 1 1/4", 3/4", 1/2" and 3/8"
Remember if you have a steep hill - the larger and sharper-angled the stone is, the better it will stay put.
And generally, the smaller the stone, the more "dressy" or uniform the look.
Trap rock, which is slate colored and occasionally called bluestone, is available in all the above sizes.
Trap rock screenings/stone dust, often used in brick and flagstone patio work, is also available. It's comprised of the dust and chips from the crushing of the rock.
Processed Stone is a mix of screenings and 3/4 or 1 1/4 stone (gravel). It packs down well and is used in driveway and highway construction as a base, and sometimes as driveway surface. It stays well. It is labor-intensive to properly spread.
The two types of washed "builder's" sand are:
Concrete Sand - coarser sand, like most beach sand. Used in concrete, sometimes
used under patio blocks, etc., and often used for installing proprietary leaching units.
Mason Sand - finer washed sand, like sand-bar sand, used (with masonry cement) to
make mortar for laying up brick or concrete block. Works well under pool liners.
Screened Fill, Screened Topsoil, Asphalt Millings (like processed stone but blacker, cheaper)
HOW MUCH DO I NEED?
For Cubic Yards: Multiply the length (say, 100') times the width (say 12', =1200)
If you covered the area a foot thick that's how many cubic feet you'd need.
So divide the area by 6 if you want the material 2 inches thick [6x2=12 inches]
or 4 if you want the material 3 inches thick [4x3=12 inches or 3 if you want 4 inches... etc.
For our example I'll choose 2" thick:
1200 divided by 6 = 200 cubic feet.
Since there's 27 cubic feet in a cubic yard, divide the cubic feet by 27.
For our example: 200 divided by 27 = 7.4 cubic yards needed.
I recommend rounding that up to 8 yards. Remember, the volume in the truck
is not graded off and packed down, it's kind of fluffed up.
If you need to convert to tons you're pretty safe with multiplying the cubic yards by 1.3.
So in our example: 7.4 yds x 1.3 = 9.6 tons.
Again, round that up to at least 10 tons.
I hope you've found this information helpful!
