Loose sandy gravel-type soil weighs approximately how many pounds per square foot?

Loose sandy gravel-type soil typically has a unit weight that reflects its composition and density. The approximate weight of this type of soil is around 100 pounds per cubic foot. This figure is often used because loose sandy gravel has a relatively low density compared to clays or compacted soils, which can significantly change in weight depending on moisture content and compaction.

Understanding the characteristics of loose sandy gravel is crucial in various applications, such as construction and agriculture. The weight impacts how much load the soil can bear and informs decisions about foundation design and drainage systems. Therefore, 100 pounds per cubic foot is a key value that professionals consider when working with this material.
