Calculating the Volume of Fill Needed
To calculate the amount of fill material needed, you’ll need to determine the volume of the area to be filled. This can be done by measuring the length, width, and depth of the area. The formula for calculating volume is:
Volume = Length x Width x Depth
For example, if you’re filling a hole that is 10 feet long, 5 feet wide, and 2 feet deep, the volume would be:
Volume = 10 x 5 x 2 = 100 cubic feet
Converting Volume to Weight
Once you have the volume of the area to be filled, you’ll need to convert this to weight to determine the amount of fill material needed. The weight of fill material can vary depending on the type and density of the material. A general rule of thumb is to assume a density of:
Soil and compost: 1-1.5 tons per cubic yard
Gravel and aggregate: 1.5-2 tons per cubic yard
Concrete and cement: 2-3 tons per cubic yard
Using the example above, if the volume of the hole is 100 cubic feet, and you’re using soil with a density of 1.25 tons per cubic yard, you would need:
Weight = Volume x Density
Weight = 100 x 1.25
Weight = 125 tons
However, since fill materials are often sold by the cubic yard, you’ll need to convert the weight to volume. A cubic yard is equal to 27 cubic feet, so:
Volume = Weight / Density
Volume = 125 / 1.25
Volume = 100 cubic feet
Volume = 100 / 27
Volume = 3.7 cubic yards
Adding a Buffer for Settlement and Compaction
It’s essential to add a buffer to your calculation to account for settlement and compaction of the fill material over time. This can range from 10-20% of the total volume, depending on the type of material and the intended use of the filled area. Using the example above, if you’re using a 15% buffer, you would need:
Buffer = Volume x 0.15
Buffer = 3.7 x 0.15
Buffer = 0.55 cubic yards
Total Volume = Volume + Buffer
Total Volume = 3.7 + 0.55
Total Volume = 4.25 cubic yards
