Sand (#4)

Sand in a #4 size range is a coarse construction aggregate, typically consisting of particles that pass through a #4 sieve (4.75 mm openings). This grading results in a sand that is noticeably coarser than standard masonry or play sand, offering unique performance characteristics for specific construction needs.

The larger particle size of #4 sand enhances drainage and reduces compaction, making it ideal for applications where water flow is important, such as in bedding for pavers, pipe bedding, or as a base layer for concrete slabs. Its coarser texture also provides stability and support in landscaping projects, helping to prevent shifting and settling. However, due to its size, #4 sand is less suitable for finishing work or applications requiring a smooth surface, such as plastering or mortar mixes.

Common uses include residential and commercial drainage systems, backfilling, and as a leveling material under patios and walkways. Its excellent drainage properties and resistance to compaction make it a practical choice for both DIYers and contractors seeking reliable performance in foundational and drainage-focused projects.
