How much does loose sandy-gravel-type soil weigh approximately per square foot?

Loose sandy-gravel-type soil typically weighs around 100 pounds per cubic foot when considering its density in lightweight, uncompressed states. This approximate weight is relevant for practical applications in construction and landscaping, where understanding soil weight is critical for load-bearing calculations and planning.

When evaluating the weight of soil, it's important to remember that types of soil vary in composition and packing density, which affects their overall weight. Sandy-gravel soil, being loose and not heavily compacted, falls into the range of about 90 to 110 pounds per cubic foot. The choice of 100 pounds is often used in calculations for estimating the weight of materials for projects such as landscaping, earthworks, and foundation planning, making it a common figure in the industry.
