The Manufacturing Pathway
Extraction
We source high-quality volcanic sand directly from the slopes of Mount Semeru in Lumajang. Our extraction process prioritizes sustainable land management and material purity.
Refinement & Washing
Using advanced hydro-cyclone technology, we remove silt, clay, and organic impurities. This intensive washing process ensures a high-quality finish and optimal bonding properties.
Sieving & Grading
Automated vibratory screens sort the washed sand into specific grain size distributions. We maintain strict adherence to industrial standards for Fine (0-2mm), Medium (2-4mm), and Coarse (4-8mm) grades.
Quality Assurance
Every batch undergoes laboratory testing for mineral composition, moisture content, and consistency. We guarantee that our sand meets the rigorous requirements for high-performance concrete.
Logistics & Delivery
Final products are packaged or loaded in bulk for dispatch. Our dedicated fleet ensures timely and safe delivery to construction sites across the region.
