How Much Aggregate Do I Need

You would usually lay a 10mm aggregate at a depth of 30-40mm, but on a driveway this would need to be at least 50mm. A 20mm aggregate would need to be at least 40-50mm deep, and at least 50-60mm on driveways. A larger aggregate will settle and bond together better than smaller ones.

How do you calculate aggregate material?

  1. Multiply the length of the area by the width of the area = Square Feet.
  2. Multiply Square Feet by the Depth* = Cubic Feet.
  3. Divide Cubic Feet by 27 = Cubic Yards.
  4. Multiply Cubic Yards by 1.5 = Tons Needed.

How do you calculate aggregate required?

  1. Cement = 1 Part.
  2. Sand = 1.5 Part.
  3. Aggregate = 3 Part.
  4. Total dry volume of ingredients required = 1.57 cu.m.
