To calculate the quantity needed for a particular job, measure the length, width, thickness and product density (located below), of the area, plug in your numbers and our aggregate calculator will estimate the amount you will need to order.
Please make sure to add 10% more to your total quantity to take into account waste during product placement.
Instructions: If you do not know the actual density, select the type of geology and product from the lists below and hit the “Estimate Density” button. An estimated density factor should then appear in the above density field.
24 ft round pool – 4″ deep
Start with 1/2 the radius:
12 x 12 = 144
144 x (3.14) x depth divided by 27 x unit weight
Example:
12 x 12 = 144
x 3.14 = 452.16
x .33 = 149.21
÷ 27 = 5.53
x 1.5 = 8.30 tons
