Washed sand and aggregate

Two purpose-made fractions, fully compliant with MNS 2803:2004 and ASTM C33/C33M.

0–5 mm
Washed micro / fine sand

A loose fine-fraction aggregate for machine-applied mortar, skim coats, castings and floor screeds. Very low silt and clay content stabilises workability and raises the compressive strength of concrete.

Washed gravel / small aggregate

An active aggregate for structural concrete, foundations and civil works. Clean and well graded, it can be used directly with no further processing.

Technology

How is the sand cleaned?

Hydrocyclone технологи
01
Hydrocyclone technology

Centrifugal force separates fine clay and silt particles from sand and aggregate at high speed, removing contamination that ordinary washing cannot. 95% of the wash water is recycled, making this one of the most environmentally friendly washing technologies in the region.

Centrifugal forceSeparation principle — removes clay and silt
95%Recycled water — closed-loop system

Sandtec fine filtration technology

A 75-micron ultra-fine filter captures the micro-particles that pass through standard filters — invisible to the eye, yet damaging to concrete quality. The result is a very dry, clean product, ready to load with no additional drying.

Applications

Where is it used?

Concrete production
  • Mortar
  • Precast concrete production
Why washed sand?
  • Reliable, durable concrete — consistent quality at every level
  • Dust- and silt-free aggregate increases compressive strength and density
  • Needs less water — the mix is easier to control
  • Ensures the quality of ready-mix concrete production
Construction
  • For general mortar
  • For floor, wall and surface finishing mortar
  • Filling
  • Decoration
Why washed sand?
  • Slurry / smooth, clean surface finish — better bonding on walls and floors
  • Lightweight and easy to work with on site
  • Reduces defects in surfaces and engineered joints
  • Ensures the long-term durability of building structures
