Quality assurance
Checked before it ships, not after
Stone that fails inspection at your end is expensive for both of us. Six checkpoints exist to stop that happening.
The principle
A defect found in Hyderabad costs a slab. The same defect found at your port costs a project.
Natural stone varies — that is the point of it. Quality control in this trade is not about eliminating variation but about controlling it: making sure the variation you receive is the variation you were shown and agreed to.
Every order passes the checkpoints below. Where a specification requires certified figures for compressive strength, water absorption or flexural strength, tell us at enquiry stage and we will arrange testing.
Checkpoints
What gets checked, and when
Block selection
Blocks are assessed at the quarry for colour consistency, crack lines and grain direction before purchase.
Gangsaw cutting
Blocks are sawn to the ordered thickness, with tolerance checked across the full slab width.
Surface finishing
Slabs are polished, honed, flamed, leathered or brushed to the specified finish and gloss level.
Shade grading
Slabs are laid out and grouped by shade so a single order ships as a visually coherent lot.
Dimensional check
Cut-to-size components are measured against the approved drawing before they leave the shop floor.
Packing & loading
Material is crated with edge protection and moisture barriers, then loaded and sealed under supervision.
Testing and documentation
Where your specification or tender requires it, we can arrange third-party testing and supply the results with the shipment.
| Compressive strength | On request — third-party tested |
|---|---|
| Water absorption | On request — third-party tested |
| Flexural strength | On request — third-party tested |
| Abrasion resistance | On request — third-party tested |
| Slip resistance | On request — relevant for flamed and bush-hammered finishes |
| Radiation / NORM | On request — required by some import markets |
Values vary between blocks and lots. Certified figures relate to the tested lot only.
Packing standard
- Seaworthy wooden crates, fumigated where the destination requires it
- Edge and corner protection on every bundle
- Moisture barriers between slabs
- Bundles grouped by shade and marked accordingly
- Cut-to-size packed in installation sequence on request
- Loading supervised and photographed before sealing
