Quality Control & Technical Documentation
Industrial capacity to deliver quality and quantity for demanding projects — with controlled processes, technical documentation and full transparency.
Control and Traceability
Processes and evidence that reduce your project risk.
Batch consistency
Selection by quarry faces and benches to reduce tonal and pattern variation.
Dimensional tolerances
Thickness control and calibration with item-by-item checks where applicable.
Reliable lead times
Phased planning (extraction, cutting and block characterisation) with confirmed dispatch dates.
Representative samples
Samples taken from the same mass/vein as the order, with cross-reference.
Final inspection
Check-list visual e dimensional antes da expedição; fotografias de produto sob pedido.
Full traceability
Detailed product information from quarrying through to dispatch.
Certifications and Declarations
Proven compliance: CE marking/DoP, management systems and supporting documents available on request.
CE marking (DoP)
Declarations of Performance for natural-stone products under harmonised standards.
Tests and reference standards
We are a certified company and comply with a broader set of EN and international standards than those listed here; this list is indicative, not exhaustive.
| Property | Standard (EN) | Notes |
|---|---|---|
| Water absorption | EN 13755 | Indicative for exterior/pools and freeze–thaw. |
| Apparent density | EN 1936 | Mass characterisation. |
| Compressive strength | EN 1926 | Structural elements and loads. |
| Flexural strength | EN 12372 | Paving, steps, facades. |
| Freeze–thaw | EN 12371 | Relevant for exterior. |
| Abrasion (Böhme) | EN 14157 | Traffic and wear. |
| Slip resistance | EN 14231 | Value/class per finish. |
How we ensure consistency
Selection by faces/veins; bench records for visual homogeneity.
Controlled processes to project tolerances.
Sorting by tone/pattern and face condition for the intended use.
Visual/dimensional checks; photographic record on request.
Transport planned with a focus on safety and material integrity.
DoP/reports attached to shipment; traceability back to quarry/sawing.
