Construction sand

Construction sand is one of the most essential raw materials in the global building industry. Sourced from natural riverbeds, quarries, or crushed rock, it plays a vital role in the production of concrete, mortar, asphalt, bricks, and various civil engineering works. Our premium-quality construction sand is carefully processed and graded to meet international construction and export standards, ensuring strength, durability, and workability in every project.

1. What Is Construction Sand?

Construction sand, also known as building sand, refers to granular materials composed mainly of fine quartz particles (SiO₂), with a balanced mix of other minerals such as feldspar, mica, and small rock fragments.

Unlike regular sand, construction sand is washed, screened, and graded to achieve the right particle distribution, free from impurities such as clay, silt, and organic matter. These features make it highly suitable for concrete, plastering, masonry, and roadwork applications.

3. Types of Construction Sand We Supply

1. River Sand

   • Naturally occurring fine sand from riverbeds.

   • Clean, smooth, and ideal for plastering and bricklaying.

   • Excellent workability and water retention for mortar applications.

2. Crushed Sand (Manufactured Sand – M-Sand)

   • Produced from crushed granite, limestone, or basalt.

   • Sharp-edged particles provide better bonding in concrete.

   • Consistent quality, free from clay and silt contamination.

3. Coarse Sand

   • Larger grain size (2.0–4.75 mm).

   • Used in reinforced concrete and road construction for improved strength.

4. Fine Sand

   • Smaller grain size (0.075–0.425 mm).

   • Ideal for plastering, tiling, and finishing work.

5. Reclamation and Filling Sand

   • Economical type used for land leveling, road sub-base, and foundation backfilling.

4. Major Applications

a. Concrete Production
Construction sand is a core ingredient in concrete, providing bulk, strength, and resistance to cracking. A well-graded sand mix enhances concrete workability and ensures long-term durability in structures such as bridges, buildings, and pavements.

b. Masonry and Plastering
Its fine texture and clean composition make it perfect for bricklaying, plastering walls, and tile bedding. It ensures smooth application and uniform finish.

c. Road and Infrastructure Projects
Coarse construction sand provides excellent compaction and load-bearing capacity, making it ideal for road base layers, asphalt mixes, and drainage systems.

d. Land Reclamation and Foundation Work
Used for filling low-lying areas, backfilling trenches, or stabilizing building foundations due to its stability and easy compaction properties.

e. Glass and Industrial Applications
High-silica construction sand can also serve as feedstock for glass manufacturing, foundry casting, and filtration systems.
