Sand/Gravel (3/8″ Minus, 50/51)

Sand/Gravel 50/51 in a 3/8” Minus Size Range

Sand/Gravel 50/51 in a 3/8" minus size range is a versatile construction aggregate composed of a blend of sand and small gravel particles, all passing through a 3/8-inch screen. The "minus" designation means the material includes everything from fine particles up to 3/8" in size, resulting in a well-graded mix that compacts efficiently.




This specific size and gradation make it ideal for applications where stability and compaction are important, such as under concrete slabs, pavers, and as a base for walkways or patios. The fine particles fill voids between larger pieces, creating a dense, stable surface that resists shifting. It is also commonly used for pipe bedding, backfill, and as a leveling layer in landscaping projects. While its excellent compaction properties are a major advantage, the presence of fines means it is less suitable for drainage applications compared to washed or larger, more open-graded aggregates.
