    Mar 01, 1986 Sand can be expected to contribute about 2 to 6 percent free moisture by weight, and gravel or stone about 1 or 2 percent. Under average conditions that means that 104 pounds of sand would give you the equivalent of 100 pounds of sand in what is called a saturated surface dry (SSD) condition and 4 pounds (1/2 gallon) of free moisture

They bind in a way that better holds the shape and consistency of the soil. 2) Granular Soils – Mostly gravels and sand with little to no clay. This soil has no cohesive strength and as a result can’t be molded together when wet and is very crumbly when dry
