In-House Quarry Resources
YUSHI STONE operates three exclusively owned granite quarries with an annual extraction capacity of 120,000 m³, enabling complete quality oversight from geological survey to finished block. Our in-house geological team conducts monthly core sampling and petrographic analysis, ensuring consistent mineral composition and density across all extraction zones—a practice that reduced material rejection rates to under 1.2% in 2024, compared to the industry average of 4–6% for third‑party sourced granite. By eliminating intermediary suppliers, we shorten typical lead times from 6–8 weeks to 3–4 weeks, based on actual order data from 2025. For a large‑scale commercial development in Sydney, direct quarry supply saved the client AUD 87,000 in logistics and expediting fees, documented in their procurement records. We provide full quarry‑to‑site traceability with each shipment, including block coordinates, extraction date, compressive strength test results (ASTM C170)
