Our Services
Accredited (L047) and Circular
We offer a wide range of accredited laboratory and field tests, including:
- Compaction tests for sand subgrades and foundation layers
- In-situ density measurements (ring-penetration and nuclear methods)
- Grain size distributions of sand, foundation material, and asphalt aggregate
- Asphalt acceptance testing
- PAH and DLC testing for environmental assessment
- Layer thickness measurements and structural composition analyses
Our tests are conducted in accordance with the EN ISO/IEC 17025:201 standard and are included in our scope of accreditation (L047). This ensures that our processes are designed to be reliable, safe, and environmentally responsible.
