Unwashed Sand

Unwashed sand is a cost-effective, coarse sand material commonly used for general filling and non-structural construction applications. Unlike washed sand, it retains fine particles such as silt and dust, which enhance its compaction properties and make it highly suitable for ground filling works.
 
This material is primarily used as a filling and packing material, where achieving good compaction and stability is essential. It is widely applied in backfilling trenches, filling voids and holes, and leveling uneven ground prior to construction. Its composition allows it to compact tightly, reducing air gaps and providing a firm, stable base.
