Petrographic Services

Why we do it

Petrography isn't just about naming minerals, it's about explaining material behaviour. We use the optical properties of rock-forming minerals as failure diagnostics, not just identification tools. This tells us what a material is actually made of, not just what it was sold or marketed as, and can explain why two materials with similar test results sometimes perform very differently. Petrography identifies problems before they show up in service, reducing technical, commercial, and reputational risk.

We get called when:

• Physical test results are inconsistent or contradictory
• A material meets specification on paper but fails in service
• Unexpected cracking, degradation, or durability issues appear
• Two sources that look the same perform very differently
• A failure mechanism needs to be explained, not just measured
• There is a dispute about material quality or compliance
• A new material behaves differently to historical supply
• A mystery rock shows up in the pit

Where it's applied

• Construction materials/concrete - explains durability issues, aggregate incompatibility, unexpected cracking or strength loss.
• Geotechnical engineering - identifies weak, weathered, or altered lithologies affecting strength, durability, or excavation behaviour.
• Mining & quarrying - characterises ore gangue, deleterious minerals, structural controls, hardness/abrasivity proxies, and variability within a resource.
• Workplace Health & Safety - identifies free silica, fibrous minerals, dust-forming constituents, and textural controls on respirable risks.
• Materials testing laboratories - explains anomalous or conflicting test results when physical data alone doesn't make sense.
• Research / academic institutions - supports rock characterisation and analysis for researchers.
• Forensics & disputes - provides defensible, visual evidence explaining failure mechanisms and material non-compliance.
