Sand (#4 Minus, Unwashed, Pre-Wet)

Sand, Unwashed, Pre-Wet, #4 Minus

#4 minus unwashed, pre-wet sand is a versatile construction aggregate consisting of fine particles that pass through a #4 sieve (approximately 4.75 mm and smaller). The "unwashed" attribute means the sand retains natural fines and clay, while "pre-wet" indicates it has been moistened prior to delivery, reducing airborne dust during handling and installation.




This specific combination is ideal for applications where moisture control and compaction are important, such as pipe bedding, backfill, and trench work. The fine, unwashed texture helps the sand compact well, making it suitable for sub-base layers under pavers or slabs. However, the presence of fines and clay can make it less suitable for drainage applications compared to washed sand. The pre-wet condition minimizes dust, improving safety and cleanliness on job sites. Overall, #4 minus unwashed, pre-wet sand is a practical choice for both residential and commercial projects requiring stable, compactable fill material.
