Sourced from northern Arizona our Black Lava Sand is screened at 3/16” minus and can contain as much as 50% fines. Lava is a porous light weight rock consisting primarily of Plagioclase, Olivine, and Augite. It is primarily used in gardening as a light weight aggregate amendment to loosen and aerate the soil. Its porous structure will help break up heavy clay soil to allow drainage while providing moisture retention.
Black Lava Sand is available to our customers in smaller quantities by mail through our online store at Amazon.
