Soil Laboratory

The Damasco Penna soil laboratory performs geotechnical testing with a high level of technical rigor, providing reliable support for projects in the infrastructure, mining, logistics, real estate, and civil construction sectors. Our services range from basic characterization tests to more complex special tests, with a focus on data precision and adherence to best practices in experimental geotechnics.

All procedures follow nationally and internationally recognized methodologies, based on ABNT and ASTM standards, as well as the requirements of ISO/IEC 17025, which guide our internal quality system, even though formal certification has not yet been issued.

We also operate mobile laboratories for quality control of earthworks, enabling on-site technical monitoring of activities such as compaction, moisture control, and material verification. This ensures agility in the release of construction stages and full traceability of results.

Our equipment undergoes regular calibration and follows a strict preventive maintenance schedule, ensuring the reliability and repeatability of results. Our technical team receives continuous training and is committed to excellence and the traceability of every test performed.

Characterization Tests

• Natural moisture content

• Natural bulk density

• Atterberg limits

• Particle size distribution (sieve and hydrometer analysis)

• Combined particle size analysis

• Specific gravity of soil particles

• Proctor compaction (standard and modified)

• California Bearing Ratio (CBR)

• Hilf tests

• Other conventional classification and compaction tests

Special Tests

• Isotropic and anisotropic triaxial tests (up to 5000 kPa)

• Direct and simple shear tests (DSS)

• Consolidation tests (oedometer)

• Specific tests according to technical requirements

Damasco Penna is committed to the reliability of data and excellence in laboratory processes, ensuring consistent technical support for decision-making in geotechnical works and studies throughout Brazil.
