Sand (Class 3A)
Applications & Uses
Sand - Class 3A Size Range
Class 3A sand is a versatile construction aggregate characterized by its specific gradation, typically featuring a coarser particle size than standard fine sands. This material is produced by screening and washing natural sand deposits to achieve a consistent Class 3A specification, ensuring reliable performance in a variety of construction settings.
The coarser texture of Class 3A sand enhances drainage and stability, making it ideal for use as a base material beneath concrete slabs, pavers, and asphalt. It is commonly used in both residential and commercial projects for bedding pipes, backfilling trenches, and as a leveling layer for patios and walkways. The larger particle size reduces compaction compared to finer sands, which improves water flow and minimizes the risk of pooling or frost heave. However, this also means it may not be suitable for applications requiring a smooth, tightly compacted finish. Overall, Class 3A sand is valued for its balance of drainage and support in foundational and landscaping projects.
